Hot stars burn brightly in this image from NASA's Galaxy Evolution Explorer, showing the UV side of a familiar face. At 2.5 million light-years away, the Andromeda galaxy is our Milky Way's largest galactic neighbor. The galaxy spans 260,000 light-years across. The bands of blue-white making up the galaxy's striking rings are neighborhoods that harbor hot, young, massive stars. Dark blue-grey lanes of cooler dust show up starkly against these bright rings, tracing the regions where star formation is currently taking place in dense cloudy cocoons. Eventually, these dusty lanes will be blown away by strong stellar winds, as the forming stars ignite nuclear fusion in their cores. Meanwhile, the central orange-white ball reveals a congregation of cooler, old stars that formed long ago. When observed in visible light, the galaxy’s rings look more like spiral arms. The UV image shows that these arms more closely resemble the ring-like structure previously observed in infrared wavelengths with NASA’s Spitzer Space Telescope; astronomers interpreted these rings as evidence that the galaxy was involved in a direct collision with its neighbor, Messier 32, more than 200 million years ago.
