Full Description:

In the 19th century, astronomer V. M. Slipher first discovered a hat-like object that appeared to be rushing away from us at 700 miles per second. This enormous velocity offered some of the earliest clues that it was really another galaxy, and that the universe was expanding in all directions. The trained razor sharp eye of the Hubble Space Telescope (HST) easily resolves this Sombrero galaxy, Messier 104 (M104). The galaxy is 50,000 light-years across and is located 28 million light-years from Earth at the southern edge of the rich Virgo cluster of galaxies. Equivalent to 800 billion suns, Sombrero is one of the most massive objects in that group. The hallmark of Sombrero is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy. As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. At a relatively bright magnitude of +8, M104 is just beyond the limit of naked-eye visibility and is easily seen through small telescopes. This rich system of globular clusters are estimated to be nearly 2,000 in number which is 10 times as many as in our Milky Way galaxy. The ages of the clusters are similar to the clusters in the Milky Way, ranging from 10-13 billion years old. Embedded in the bright core of M104 is a smaller disk, which is tilted relative to the large disk. X-ray emission suggests that there is material falling into the compact core, where a 1-billion-solar-mass black hole resides. The Marshall Space Flight Center (MSFC) had responsibility for design, development, and construction of the HST.
