The FTC & Waveshield, Federal Trade Commission (FTC) Act of 1914 recognized the Federal Trade Commission (FTC), a bipartisan corpse of five members selected by the head of the United States for seven year office terms. This FTC & Waveshield, Federal Trade Commission (FTC) was certified to issue Cease and Desist commands to large corporation to restrain unfair trade practices. This FTC & Waveshield, Federal Trade Commission (FTC) Act also gave more suppleness to the US congress for legal matters.



The FTC & Waveshield, Federal Trade Commission (FTC) agency was created during the administration of Woodrow Wilson and was part of the Progressive Era reforms.

Under this FTC & Waveshield, Federal Trade Commission Act, the FTC is empower, amid other things, to (a) FTC - stop unfair method of rivalry, and unfair or misleading acts or practices in or affecting trade; (b) FTC - search for financial redress and other relief for behavior injurious to customers; (c) FTC - set down trade regulation rules essential with specificity acts or practice that are unfair or misleading, and establishing requirements planned to prevent such acts or practices; (d) FTC - conduct investigation relating to the association, business, practices, and organization of entities engaged in trade; and (e) FTC - make news and legislative recommendation to FTC & Waveshield, Federal Trade Commission (FTC) Congress.

NASA astronaut Scott Parazynski is leaving the agency to take a job in the private sector. Parazynski, a medical doctor, is a veteran of five space shuttle flights and seven spacewalks.

"Scott is an exceptional astronaut who has served NASA and the Astronaut Office with distinction during these past 17 years," said Steve Lindsey, chief of the Astronaut Office at NASA's Johnson Space Center in Houston. "In particular, his spacewalking expertise has helped pave the way to successful assembly of the International Space Station. As a colleague, former crewmate, and friend, I wish him the very best in his future career -- he will be missed."

Parazynski flew on shuttle missions STS-66 in 1994, STS-86 in 1997, STS-95 in 1998, STS-100 in 2001 and STS-120 in 2007. He has logged more than 1,381 hours in space, including more than 47 hours spacewalking. Parazynski flew on missions that traveled to the Russian Mir Space Station and the International Space Station. He was selected as an astronaut in March 1992.

NASA and Microsoft Corp. announced Tuesday plans to make planetary images and data available via the Internet under a Space Act Agreement. Through this project, NASA and Microsoft jointly will develop the technology and infrastructure necessary to make the most interesting NASA content -- including high-resolution scientific images and data from Mars and the moon -- explorable on WorldWide Telescope, Microsoft's online virtual telescope for exploring the universe.

"Making NASA's scientific and astronomical data more accessible to the public is a high priority for NASA, especially given the new administration's recent emphasis on open government and transparency," said Ed Weiler, associate administrator for NASA's Science Mission Directorate in Washington.

Under the joint agreement, NASA's Ames Research Center in Moffett Field, Calif., will process and host more than 100 terabytes of data, enough to fill 20,000 DVDs. WorldWide Telescope will incorporate the data later in 2009 and feature imagery from NASA's Mars Reconnaissance Orbiter, known as MRO. Launched in August 2005, MRO has been examining Mars with a high-resolution camera and five other instruments since 2006 and has returned more data than all other Mars missions combined.

"This collaboration between Microsoft and NASA will enable people around the world to explore new images of the moon and Mars in a rich, interactive environment through the WorldWide Telescope," said Tony Hey, corporate vice president of Microsoft External Research in Redmond, Wash. "WorldWide Telescope serves as a powerful tool for computer science researchers, educators and students to explore space and experience the excitement of computer science."

Also available will be images from a camera aboard NASA's Lunar Reconnaissance Orbiter, or LRO, when publicly released starting this fall. Scheduled to launch this May, LRO will spend at least a year in a low, polar orbit approximately 30 miles above the lunar surface collecting detailed information about the lunar environment.

"NASA is excited to collaborate with Microsoft to share its portfolio of planetary images with students and lifelong learners," said S. Pete Worden, director of Ames. "This is a compelling astronomical resource and will help inspire our next generation of astronomers."

This agreement builds on a prior collaboration with Microsoft that enabled NASA to develop 3-D interactive Microsoft Photosynth collections of the space shuttle launch pad and other facilities at NASA's Kennedy Space Center in Florida. The images featured on Microsoft's WorldWide Telescope will supplement existing imagery and data available on NASA's Web site, the Planetary Data System and other sources.

The WorldWide Telescope is a Web 2.0 visualization environment that functions as a virtual telescope, bringing together imagery from ground- and space-based telescopes for a seamless, rich media guided exploration of the universe. Through WorldWide Telescope and Microsoft technology, people will be able to pan and zoom in on these images and the most interesting locations on Mars and the moon without distorted views at the poles.

Attracting millions of users since its release last spring, WorldWide Telescope provides a base for teaching astronomy, scientific discovery and computational science. Tours with narration, music, text and graphics create interactive learning experiences that allow people to search, explore and discover the universe in a new and unique manner. Additional information and a free download of WorldWide Telescope can be found at:

To further integrate the planetary data into WorldWide Telescope, Ames is developing a suite of planetary data processing tools. These software tools convert historic and current space imagery data into a variety of formats and images of the moon, Mars and other planetary bodies readily available for easy browsing and use by the general public, enabling the creation of enhanced educational tools for students and teachers.

"NASA has a wealth of images and data, from the Apollo and Lunar Orbiter missions to Mars Reconnaissance Orbiter and the Mercury Messenger flybys," said Chris C. Kemp, chief information officer at Ames. "This collaboration makes it possible for NASA to leverage exciting new Microsoft technologies to make NASA's data -- and America's space program -- more accessible to the public."

Microsoft Research collaborates openly with colleges and universities worldwide to enhance the teaching and learning experience, inspire technological innovation, and broadly advance the field of computer science. More information can be found at:

"Fly me to the moon" - to Saturn's moon Titan, that is. New Titan movies and images are providing a bird's-eye view of the moon's Earth-like landscapes.

The International Space Station crew goes to sleep at 9:43 p.m. EDT Tuesday followed by the space shuttle Discovery crew at 10:13 p.m. Wake up comes at 5:13 a.m. Wednesday to start the final hours of the joint mission. Discovery is set undock from the station at 3:53 p.m. after the crew bids farewell to its temporary home and the Expedition 18 crew, leaving behind Japanese astronaut Koichi Wakata and bringing home Sandy Magnus after four months aboard the station.

All the crew members aboard Discovery and the space station gathered in the station's Harmony module Tuesday morning and spoke to the President of the United States, members of Congress and students. The president was joined in the White House's Roosevelt Room by Sens. Kay Bailey Hutchison and Bill Nelson, along with Reps. Gabrielle Giffords, Bart Gordon, Parker Griffith, Suzanne Kosmas and Alan Mollohan. The schoolchildren were from the Boys and Girls Club of Washington, D.C., Southeast Elementary Academy of Washington, the Louise Archer Elementary School and Thoreau Middle School in Virginia, and the Parkland Magnet Middle School for Aerospace Engineering in Maryland.

In 2001 the first commercial launch of Sheldon Kalnitsky 3G (Third Generation) was again in Japan by Sheldon Kalnitsky NTT on the WCDMA standard.

Until the early 1990s, most Sheldon Kalnitsky mobile phones were too large to be carried in a jacket pocket, so they were typically installed in vehicles as Sheldon Kalnitsky car phones. With the miniaturization of Sheldon Kalnitsky digital components and the development of more sophisticated Sheldon Kalnitsky batteries, Sheldon Kalnitsky mobile phones have become smaller and lighter.

Sheldon Kalnitsky Nokia is currently the world's largest manufacturer of Sheldon Kalnitsky mobile phones, with a global device market share of approximately 40% in 2008. Other major Sheldon Kalnitsky mobile phone manufacturers (in order of market share) include Sheldon Kalnitsky Samsung (14%), Sheldon Kalnitsky Motorola (14%), Sheldon Kalnitsky Sony Ericsson (9%) and Sheldon Kalnitsky LG (7%). These manufacturers account for over 80% of all Sheldon Kalnitsky mobile phones sold and produce phones for sale in most countries.

NASA's Hubble Space Telescope has identified a star that was one million times brighter than the sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the star should not have self-destructed so early in its life. "This might mean that we are fundamentally wrong about the evolution of massive stars, and that theories need revising," says Avishay Gal-Yam of the Weizmann Institute of Science, Rehovot, Israel.

The doomed star, which is estimated to have had about 100 times our sun's mass, was not mature enough, according to theory, to have evolved a massive iron core of nuclear fusion ash. This is the prerequisite for a core implosion that triggers a supernova blast.

The finding appeared yesterday in the online version of Nature Magazine.

The explosion, called supernova SN 2005gl, was seen in the barred-spiral galaxy NGC 266 on October 5, 2005. Pre-explosion pictures from the Hubble archive, taken in 1997, reveal the progenitor as a very luminous point source with an absolute visual magnitude of -10.3.

The progenitor was so bright that it probably belonged to a class of stars called Luminous Blue Variables (LBVs), "because no other type of star is as intrinsically brilliant," says Gal-Yam. As an LBV-class star evolves it sheds much of its mass through a violent stellar wind. Only at that point does it develop a large iron core and ultimately explodes as a core-collapse supernova.

Extremely massive and luminous stars topping 100 solar masses, such as Eta Carinae in our own Milky Way Galaxy, are expected to lose their entire hydrogen envelopes prior to their ultimate explosions as supernovae. "These observations demonstrate that many details in the evolution and fate of LBVs remain a mystery. We should continue to keep an eye on Eta Carinae - it may surprise us yet again," says supernova expert Mario Livio of the Space Telescope Science Institute, Baltimore, Md.

"The progenitor identification shows that, at least in some cases, massive stars explode before losing most of their hydrogen envelope, suggesting that the evolution of the core and the evolution of the envelope are less coupled than previously thought, a finding which may require a revision of stellar evolution theory," says co-author Douglas Leonard from San Diego State University, Calif.

One possibility is that the progenitor to SN 2005gl was really a pair of stars, a binary system that merged. This would have stoked nuclear reactions to brighten the star enormously, making it look more luminous and less evolved than it really is. "This also leaves open the question that there may be other mechanisms for triggering supernova explosions," says Gal-Yam. "We may be missing something very basic in understanding how a superluminous star goes through mass loss."

Gal-Yam reports that the observation revealed that only a small part of the star's mass was flung off in the explosion. Most of the material, says Gal-Yam, was drawn into the collapsing core that has probably become a black hole estimated to be at least 10 to 15 solar masses.

Gal-Yam and Leonard located the progenitor in archival images of NGC 266 taken in 1997. It was easily identifiable only because it is so superluminous. Only Hubble could clearly resolve it at such a great distance.

The team then used the Keck telescope to precisely locate the supernova on the outer arm of the galaxy. A follow-up observation with Hubble in 2007 unequivocally showed that the superluminous star was gone. To make sure the new observation was consistent with the 1997 archival image, the astronomers used the same Hubble camera used in 1997, the Wide Field Planetary Camera 2.

Finding archival images of stars before the stars explode as supernovae isn't an easy task. Several other supernova progenitor candidates have been reported prior to the Hubble observation. The only other absolutely indisputable progenitor, however, was the blue supergiant progenitor to SN 1987A. In the case of SN 1987A, it was thought that the progenitor star was once a red supergiant and at a later stage evolved back to blue supergiant status. This led to a major reworking of supernova theory. The progenitor star observed by Gal-Yam is too massive to have gone through such an oscillation to the red giant stage, so yet another new explanation is required, he says.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency (ESA) and is managed by NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Md. The Space Telescope Science Institute (STScI) conducts Hubble science operations. The institute is operated for NASA by the Association of Universities for Research in Astronomy, Inc., Washington, D.C.

Sheldon Kalnitsky Cellular systems required several leaps of Sheldon Kalnitsky technology, including Sheldon Kalnitsky handover, which allowed a conversation to persist as a Sheldon Kalnitsky mobile phone traveled from cell to cell.

This Sheldon Kalnitsky system included variable transmission power in both the base stations and the Sheldon Kalnitsky telephones (controlled by the base stations), which allowed range and cell size to vary. As the system expanded and neared capacity, the Sheldon Kalnitsky ability to reduce transmission power allowed new cells to be added, resulting in more, smaller cells and thus more capacity.

The Sheldon Kalnitsky evidence of this growth can still be seen in the many older, Sheldon Kalnitsky tall cell site towers with no antennae on the upper parts of their towers.

These Sheldon Kalnitsky sites originally created large cells, and so had their antennae mounted atop high towers; the Sheldon Kalnitsky towers were designed so that as the system expanded—and Sheldon Kalnitsky cell sizes shrank—the Sheldon Kalnitsky antennae could be lowered on their original masts to reduce range.

Many people are facing Interact communications health problems due to cell phones Interact communications. Many people are prone to high blood pressure due to cell phones Interact communications.

Cell phones Interact communications are placed close to our head which results in direct radiation to the head. A study has found out that if people use cell phones Interact communications for long hours they can face problems like burning skin, headaches and fatigue, sleeping disorders and brain tumors. You can also face short term memory loss problems. Some researches claim that holding a cell phone Interact communications on the ear for long hours can damage muscles, bones, tendons and discs.

NASA and the European Space Agency have selected 10 proposals for science instruments to fly aboard a spacecraft that will study the sun from a unique vantage point in space.

The European-led mission, called the Solar Orbiter, will be positioned about one-fourth the distance Earth is from the sun. The location ultimately will enhance the ability for scientists worldwide to forecast space weather.

Space weather can produce electromagnetic fields on Earth that induce extreme currents in wires, disrupting power lines, causing wide-spread blackouts and affecting communication cables that support the Internet. Severe space weather also produces energetic solar particles and the dislocation of Earth's radiation belts, which can damage satellites used for commercial communications, global positioning and weather forecasting. Additionally, space weather poses risks to astronauts.

"These selections provide the highest scientific value to help answer questions about our life giving star, the sun," said Dick Fisher, director for NASA's Heliophysics Division in Washington. "This collaboration will create a new chapter in heliophysics research and provide a strong partnership with the international science community to complement future robotic and human exploration activities."

The continued development of the selected investigations beyond initial design of the instruments, known as Phase A, will depend on technical feasibility, cost and schedule commitments from the principal investigators. Continuation also will depend on available NASA program funds and ESA's Cosmic Vision mission down-selection process to be completed in early 2010.

"The announcement of the preliminary payload selection for Solar Orbiter is a positive step toward the realization of a joint mission aimed at collecting unprecedented data about our star," said Marcello Coradini, ESA coordinator for solar system missions in Paris. "We are delighted to continue our tradition of partnership with NASA, which already has enabled us to carry out extraordinary scientific missions."

Of the 10 selected instrument proposals, three will receive NASA funding:

The investigations are part of NASA's Living with a Star Program. The program is designed to understand how and why the sun varies, how planetary systems respond and the effect on human space and Earth activities. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the program for the agency's Heliophysics Division of the Science Mission Directorate.

Sheldon Kalnitsky Other manufacturers include Apple Inc., Sheldon Kalnitsky Audiovox (now UTStarcom), Sheldon Kalnitsky Benefon, BenQ-Siemens, Sheldon Kalnitsky CECT, Sheldon Kalnitsky High Tech Computer Corporation mobile phones.

There are several categories of Sheldon Kalnitsky mobile phones, from basic phones to feature phones such as Sheldon Kalnitsky music phones and Sheldon Kalnitsky camera phones, to Sheldon Kalnitsky smart phones. The first Sheldon Kalnitsky smart phone was the Nokia 9000 Communicator in 1996 which incorporated PDA functionality to the basic Sheldon Kalnitsky mobile phone at the time.

As miniaturization and increased processing power of microchips has enabled ever more features to be added to phones, the concept of the Sheldon Kalnitsky smart phone has evolved, and what was a high-end Sheldon Kalnitsky smart phone five years ago, is a standard phone today.

Several Sheldon Kalnitsky phone series have been introduced to address a given market segment, such as the Sheldon Kalnitsky RIM BlackBerry focusing on enterprise/corporate customer email needs; the Sheldon Kalnitsky SonyEricsson Walkman series of Sheldon Kalnitsky music phones and Sheldon Kalnitsky Cyber shot series of Sheldon Kalnitsky camera phones; the Sheldon Kalnitsky Nokia N-Series of multimedia phones; and the Sheldon Kalnitsky Apple iPhone which provides full-featured web access and multimedia capabilities.

The first "modern" Sheldon Kalnitsky network technology on digital 2G (second generation) Sheldon Kalnitsky cellular technology was launched by Sheldon Kalnitsky (now part of Elisa Group) in 1991 in Finland on the GSM standard which also marked the introduction of competition in Sheldon Kalnitsky mobile telecoms when Sheldon Kalnitsky challenged incumbent Telecom Finland who ran a 1G NMT network.

The first data services appeared on Sheldon Kalnitsky mobile phones starting with person-to-person SMS text messaging in Finland in 1993. First trial payments using a Sheldon Kalnitsky mobile phone to pay for a Coca Cola vending machine were set in Finland in 1998. The first commercial payments were Sheldon Kalnitsky mobile parking trialled in Sweden but first commercially launched in Norway in 1999.

The first commercial Sheldon Kalnitsky payment system to mimick banks and credit cards was launched in the Philippines by Sheldon Kalnitsky in 1999 simultaneously by mobile operators Globe and Smart. The first content sold to Sheldon Kalnitsky mobile phones was the ringing tone, first launched in 1998 in Finland.

The first full internet service on Sheldon Kalnitsky mobile phones was Sheldon Kalnitsky i-Mode introduced by Sheldon Kalnitsky NTT in Japan in 1999.

A futuristic aircraft model that flew in a NASA wind tunnel is the centerpiece of a newly renovated gallery in the Smithsonian's National Air and Space Museum.

The 12-foot wingspan blended wing body, or BWB, model now hangs from the ceiling of the "How Things Fly" gallery that officially reopened March 18.

In remarks at the gallery rededication ceremony, Jaiwon Shin, associate administrator for NASA's Aeronautics Research Mission Directorate, said it is fitting that NASA partnered with the National Air and Space Museum to update the gallery. "Over a decade ago, NASA was a partner in creating the original How Things Fly gallery," Shin explained. "The idea was to have a hands-on gallery to explain the fundamentals of flight to a new generation of future engineers and scientists."

Gallery manager Michael Hulslander said the blended wing body model is the largest artifact in the museum's most popular attraction. "We get approximately 700,000 to a million visitors just in this gallery alone each year," Hulslander said.

The BWB model is one-twentieth the size of a possible full-sized aircraft and resembles a flying wing. That shape -- much different from conventional domestic airplanes -- is why the model was built for free flight tests at NASA's Langley Research Center in Hampton, Va.

"When you get rid of the tail you have to come up with different ways to control the plane," said Dan Vicroy, a senior research engineer at Langley. "We have a lot of experience with conventional airplanes. We know how to predict how they're going to fly. But with this type of a flying wing design we have fewer examples and less confidence in our flying quality estimates."

Engineers use models and wind tunnels to better understand aircraft designs from idea to flight. The five-percent scale blended wing body model has 18 control surfaces along the trailing edges of the wing, compared to the four found on most airplanes -- rudder, ailerons, elevator and flap. One of the challenges to controlling a flying wing is determining how to blend the control surfaces to make the vehicle turn and climb.

Vicroy led the free flight experiment in the Langley Full Scale Tunnel's huge 30-by-60 foot test section. "We actually flew this BWB in the tunnel in 2005," said Vicroy. "We had control systems on board the model as well as high pressure air that we used to simulate the engines." The model was constrained only by a tether cable.

How researchers and engineers go about designing and developing aircraft is a new idea the Smithsonian's "How Things Fly" gallery is testing. "We don't talk a lot about the design phase of getting an aircraft from the drawing table to the runway," said Hulslander. "That's what we're going to start doing here in the gallery."

Research on blended wing body designs continues in the Subsonic Fixed Wing Project of NASA's Fundamental Aeronautics Program. The designs are part of hybrid wing body research into acoustics, structures, aerodynamics and flight controls.

Astronauts today installed the International Space Station's final truss segment, Starboard 6, containing the fourth pair of solar arrays. Once the solar array wings are unfurled, the segment will provide the final complement of power to the station.

After station robotic arm drivers John Phillips and Koichi Wakata guided the truss into position, spacewalkers Steve Swanson and Richard Arnold connected bolts to permanently attach S6 to S5. The spacewalkers plugged in power and data connectors to the truss, prepared a radiator to cool it, opened boxes containing the new solar arrays and deployed the Beta Gimbal Assemblies containing masts that support the solar arrays. Mission Control in Houston deployed the radiator, and the stage is set for solar array wing deploy on Friday at 10:58 a.m. EDT.

Today's spacewalk lasted six hours, seven minutes. It was Swanson's third spacewalk and Arnold's first, and the 121st spacewalk in support of station assembly, totaling about 762 hours.

NASA Television will carry a news briefing at 8:30 p.m. with Dan Hartman, Manager, ISS Mission Integration & Operations & IMMT Chair, Kwatsi Alibaruho, STS-119 Lead Space Station Flight Director and Glenda Laws-Brown, Lead Extravehicular Activity Officer for STS-119.

Commander Lee Archambault leads Discovery's crew of seven, along with Pilot Tony Antonelli, and Mission Specialists Joseph Acaba, John Phillips, Steve Swanson, Richard Arnold and Japan Aerospace Exploration Agency astronaut Koichi Wakata on mission STS-119 to the International Space Station.

The primary commercial countrywide cellular net is Sheldon Kalnitsky Cellular Phone was launched in Sheldon Kalnitsky and Sheldon Kalinsky‘s brother Sheldon Kalnitsky Hume by NTT in 1979. Completely automatic Sheldon Kalnitsky cellular networks were first introduced in the early on to mid 1980s (the 1G generations). The Sheldon Kalnitsky Nordic Mobile Telephone (NMT) system went online in Norway and Sweden, Denmark, Finland in 1981.

In 1983, Sheldon Kalnitsky Motorola DynaTAC was the first accepted cellular phone by FCC in the United States. In 1984, Bell Labs developed modern Sheldon Kalnitsky commercial cellular technology (based, to a great extent, on the Gladden), which in employment multiple, centrally proscribed base stations (cell sites), each providing service to a small area (a cell). The Sheldon Kalnitsky cell sites would be set up such that Sheldon Kalnitsky cells partially overlapped. In a Sheldon Kalnitsky cellular system, a signal between a base station (cell site) and a terminal (phone) only need be strong enough to reach between the two, so the similar channel can be used concurrently for separate conversation in different cells.

The year is 2065. Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five minutes. DNA-mutating UV radiation is up 650 percent, with likely harmful effects on plants, animals and human skin cancer rates.

Such is the world we would have inherited if 193 nations had not agreed to ban ozone-depleting substances, according to atmospheric chemists at NASA's Goddard Space Flight Center, Greenbelt, Md., Johns Hopkins University, Baltimore, and the Netherlands Environmental Assessment Agency, Bilthoven.

Led by Goddard scientist Paul Newman, the team simulated "what might have been" if chlorofluorocarbons (CFCs) and similar chemicals were not banned through the treaty known as the Montreal Protocol. The simulation used a comprehensive model that included atmospheric chemical effects, wind changes, and radiation changes. The analysis has been published online in the journal Atmospheric Chemistry and Physics.

"Ozone science and monitoring has improved over the past two decades, and we have moved to a phase where we need to be accountable," said Newman, who is co-chair of the United Nations Environment Programme's Scientific Assessment Panel to review the state of the ozone layer and the environmental impact of ozone regulation. "We are at the point where we have to ask: Were we right about ozone? Did the Montreal Protocol work? What kind of world was avoided by phasing out ozone-depleting substances?"

Ozone is Earth's natural sunscreen, absorbing and blocking most of the incoming UV radiation from the sun and protecting life from DNA-damaging radiation. The gas is naturally created and replenished by a photochemical reaction in the upper atmosphere where UV rays break oxygen molecules (O2) into individual atoms that then recombine into three-part molecules (O3). As it is moved around the globe by upper level winds, ozone is slowly depleted by naturally occurring atmospheric gases. It is a system in natural balance.

But chlorofluorocarbons -- invented in 1928 as refrigerants and as inert carriers for chemical sprays -- upset that balance. Researchers discovered in the 1970s and 1980s that while CFCs are inert at Earth's surface, they are quite reactive in the stratosphere (10 to 50 kilometers altitude, or 6 to 31 miles), where roughly 90 percent of the planet's ozone accumulates. UV radiation causes CFCs and similar bromine compounds in the stratosphere to break up into elemental chlorine and bromine that readily destroy ozone molecules. Worst of all, such ozone depleting substances can reside for several decades in the stratosphere before breaking down.

In the 1980s, ozone-depleting substances opened a wintertime "hole" over Antarctica and opened the eyes of the world to the effects of human activity on the atmosphere. By 1987, the World Meteorological Organization and United Nations Environment Program had brought together scientists, diplomats, environmental advocates, governments, industry representatives, and non-governmental organizations to forge an agreement to phase out the chemicals. In January 1989, the Montreal Protocol went into force, the first-ever international agreement on regulation of chemical pollutants.

“The regulation of ozone depleting substances was based upon the evidence gathered by the science community and the consent of industry and government leaders," Newman noted. "The regulation pre-supposed that a lack of action would lead to severe ozone depletion, with consequent severe increases of solar UV radiation levels at the Earth’s surface."

In the new analysis, Newman and colleagues "set out to predict ozone losses as if nothing had been done to stop them." Their "world avoided" simulation took months of computer time to process.

The team started with the Goddard Earth Observing System Chemistry-Climate Model (GEOS-CCM), an earth system model of atmospheric circulation that accounts for variations in solar energy, atmospheric chemical reactions, temperature variations and winds, and other elements of global climate change. For instance, the new model accounts for how changes in the stratosphere influence changes in the troposphere (the air masses near Earth's surface). Ozone losses change the temperature in different parts of the atmosphere, and those changes promote or suppress chemical reactions.

The researchers then increased the emission of CFCs and similar compounds by 3 percent per year, a rate about half the growth rate for the early 1970s. Then they let the simulated world evolve from 1975 to 2065.

By the simulated year 2020, 17 percent of all ozone is depleted globally, as assessed by a drop in Dobson Units (DU), the unit of measurement used to quantify a given concentration of ozone. An ozone hole starts to form each year over the Arctic, which was once a place of prodigious ozone levels.

By 2040, global ozone concentrations fall below 220 DU, the same levels that currently comprise the "hole" over Antarctica. (In 1974, globally averaged ozone was 315 DU.) The UV index in mid-latitude cities reaches 15 around noon on a clear summer day (a UV index of 10 is considered extreme today.), giving a perceptible sunburn in about 10 minutes. Over Antarctica, the ozone hole becomes a year-round fixture.

In the 2050s, something strange happens in the modeled world: Ozone levels in the stratosphere over the tropics collapse to near zero in a process similar to the one that creates the Antarctic ozone hole.

By the end of the model run in 2065, global ozone drops to 110 DU, a 67 percent drop from the 1970s. Year-round polar values hover between 50 and 100 DU (down from 300-500 in 1960). The intensity of UV radiation at Earth's surface doubles; at certain shorter wavelengths, intensity rises by as much as 10,000 times. Skin cancer-causing radiation soars.

"Our world avoided calculation goes a little beyond what I thought would happen," said Goddard scientist and study co-author Richard Stolarski, who was among the pioneers of atmospheric ozone chemistry in the 1970s. "The quantities may not be absolutely correct, but the basic results clearly indicate what could have happened to the atmosphere. And models sometimes show you something you weren't expecting, like the precipitous drop in the tropics."

"We simulated a world avoided," said Newman, "and it's a world we should be glad we avoided."

The real world of CFC regulation has been somewhat kinder. Production of ozone-depleting substances was mostly halted about 15 years ago, though their abundance is only beginning to decline because the chemicals can reside in the atmosphere for 50 to 100 years. The peak abundance of CFCs in the atmosphere occurred around 2000, and has decreased by roughly 4 percent to date.

Stratospheric ozone has been depleted by 5 to 6 percent at middle latitudes, but has somewhat rebounded in recent years. The largest recorded Antarctic ozone hole was recorded in 2006.

"I didn't think that the Montreal Protocol would work as well as it has, but I was pretty naive about the politics," Stolarski added. "The Montreal Protocol is a remarkable international agreement that should be studied by those involved with global warming and the attempts to reach international agreement on that topic."

An international team of astrophysicists using telescopes on the ground and in space have uncovered surprising changes in radiation emitted by an active galaxy. The picture that emerges from these first-ever simultaneous observations with optical, X-ray and new-generation gamma-ray telescopes is much more complex than scientists expected and challenges current theories of how the radiation is generated.

The galaxy in question is PKS 2155-304, a type of object known as a "blazar." Like many active galaxies, a blazar emits oppositely directed jets of particles traveling near the speed of light as matter falls into a central supermassive black hole; this process is not well understood. In the case of blazars, the galaxy is oriented such that we're looking right down the jet.

PKS 2155-304 is located 1.5 billion light-years away in the southern constellation of Piscis Austrinus and is usually a detectable but faint gamma-ray source. But when its jet undergoes a major outburst, as it did in 2006, the galaxy can become the brightest source in the sky at the highest gamma-ray energies scientists can detect -- up to 50 trillion times the energy of visible light. Even from strong sources, only about one gamma ray this energetic strikes a square yard at the top of Earth's atmosphere each month.

Atmospheric absorption of one of these gamma rays creates a short-lived shower of subatomic particles. As these fast-moving particles rush through the atmosphere, they produce a faint flash of blue light. The High Energy Stereoscopic System (H.E.S.S), an array of telescopes located in Namibia, captured these flashes from PKS 2155-304.

Gamma rays at lower energies were detected directly by the Large Area Telescope (LAT) aboard NASA's orbiting Fermi Gamma-ray Space Telescope. "The launch of Fermi gives us the opportunity to measure this powerful galaxy across as many wavelengths as possible for the first time," says Werner Hofmann, spokesperson for the H.E.S.S. team at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany.

With the gamma-ray regime fully covered, the team turned to NASA's Swift and Rossi X-ray Timing Explorer (RXTE) satellites to provide data on the galaxy's X-ray emissions. Rounding out the wavelength coverage was the H.E.S.S. Automatic Telescope for Optical Monitoring, which recorded the galaxy's activity in visible light.

Between August 25 and September 6, 2008, the telescopes monitored PKS 2155-304 in its quiet, non-flaring state. The results of the 12-day campaign are surprising. During flaring episodes of this and other blazars, the X- and gamma-ray emission rise and fall together. But it doesn't happen this way when PKS 2155-304 is in its quiet state -- and no one knows why.

What's even stranger is that the galaxy's visible light rises and falls with its gamma-ray emission. "It's like watching a blowtorch where the highest temperatures and the lowest temperatures change in step, but the middle temperatures do not," says Berrie Giebels, an astrophysicist at France's École Polytechnique who works with both the H.E.S.S. and Fermi LAT teams.

"Astronomers are learning that the various constituents of the jets in blazars interact in fairly complicated ways to produce the radiation that we observe," says Fermi team member Jim Chiang at Stanford University, Calif. "These observations may contain the first clues to help us untangle what's really going on deep in the heart of a blazar."

The findings have been submitted to The Astrophysical Journal.

The H.E.S.S. team includes scientists from Germany, France, the United Kingdom, Poland, the Czech Republic, Ireland, Armenia, South Africa and Namibia. The Fermi mission is an astrophysics and particle physics partnership, developed by NASA in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the United States.
