The sun at solstice

This photo, taken in 2004 by the space-based Solar and Heliospheric Observatory (SOHO), shows the sun in its summer solstice position on Earth. It is a false-color composite of three images taken by SOHO. The different colors show the different temperatures on the star, with red being the hottest, blue slightly behind and green as (relatively) the coolest. Experts estimate that fewer than five percent of stars in the Milky Way are as bright or as massive as the sun. But there are stars that are 100 times as big as our sun and 100,000 times as bright.
