Located 28 million light-years from Earth, Messier 104 — also called the Sombrero galaxy or M104 — is notable for its nearly edge-on orientation as seen from our planet. Spitzer observations were the first to reveal the smooth, bright ring of dust (seen in red) circling the galaxy. Spitzer's full view also shows the disk is warped, often the result of a gravitational encounter with another galaxy, and clumpy areas spotted in the far edges of the ring indicate young star-forming regions. Hubble Space Telescope data showing starlight appears blue.
