NuSTAR Bringing the High Energy Universe into Focus

The galaxy Messier 82 (M82) is seen here in two different lights. A visible-light view from NASA's Hubble Space Telescope is at left, and an X-ray view from NASA's Chandra X-ray Observatory is at right. The comparison highlights how different the universe can look when viewed in other wavelengths of light. M82 is located 12 million light-years away in the Ursa Major constellation.
