Reds are relatively cool (about 60,000 Kelvin, or 107,540 F); blues and greens are hotter (greater than 1 million Kelvin, or 1,799,540 F). Credit: NASA/Goddard/SDO AIA Team
The new observatory gives us a view of the sun in dynamic formats and is referred to, by NASA, as one of the most advanced spacecrafts ever launched.
