If you look closely at this image of NGC 2770, a spiral galaxy 102 million light years away, you can see the structure of the galaxy's hot, moderate and cool stars. The composite image includes ultraviolet and green light, to show the clumps of hot newly formed stars in the galaxy's spiral arms, and deep red colors, highlighting the smoother distribution of cool older stars. This is the first image released by the Large Binocular Telescope, which claims to be the world's most powerful telescope.

The Large Binocular Telescope, in Arizona, combines the light from two 28-foot primary mirrors to create the resolution of a single 75-foot telescope. [Large Binocular Telescope]
