IRIS means Interface Region Imaging Spectrograph. A new solar observatory was launched into orbit around earth on June 27, 2013. IRIS observes the sun's atmosphere in low level, Interface region means moving constantly. IRIS helps for understanding the detailed images on particular area, even more turbulence and complexity than expected. By using this, we can easily understand how the solar material reaches million of degrees.

On all observation IRIS captures two kinds of data, it collects images and also data called spectra. Spectra are an important tool in IRIS arsenal to understand the interface region. Scientists easily measure the velocity, temperature and density of the solar material, it provides causes of eruptions.
