Editorial Review: NASA's Hubble Space Telescope has trained its razor-sharp eye on one of the universe's most stately and photogenic galaxies, the Sombrero galaxy, Messier 104 (M104). The galaxy's hallmark 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 south of its equatorial plane. This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat.
At a relatively bright magnitude of +8, M104 is just beyond the limit of naked-eye visibility and is easily seen through small telescopes. The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns. The galaxy is 50,000 light-years across and is located 28 million light-years from Earth.
Hubble easily resolves M104's rich system of globular clusters, estimated to be nearly 2,000 in number 10 times as many as orbit our Milky Way galaxy. The ages of the clusters are similar to the clusters in the Milky Way, ranging from 10-15 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.
In the 19th century, some astronomers speculated that M104 was simply an edge-on disk of luminous gas surrounding a young star, which is prototypical of the genesis of our solar system. But in 1912, astronomer V. M. Slipher discovered that the hat-like object appeared to be rushing away from us at 700 miles per second.

Editorial Review: Abell 2104 - Cluster of galaxies 2 billion light years from Earth. Chandra's observation of A2104 revealed six bright X-ray sources due to active supermassive black holes located in red galaxies. This surprised astronomers, because powerful X-ray emission from black holes requires large supplies of interstellar gas to feed the black holes, and red galaxies -- composed of older stars - are thought to have a sparse supply of gas. One possibility is that a galaxy can retain a supply of gas and dust deep in its core near the supermassive black hole, even in the harsh environment of a galaxy cluster.

Editorial Review: The Apollo 11 Saturn V space vehicle lifted off with Astronauts Neil A. Armstrong, Michael Collins and Edwin E. Aldrin Jr., at 9:32 a.m. EDT July 16, 1969, from Kennedy Space Center's Launch Complex 39A. During the planned eight-day mission, Armstrong and Aldrin will descend in a lunar module to the Moon's surface while Collins orbits overhead in the command module.
The two astronauts are to spend 22 hours on the Moon, including two and one-half hours outside the lunar module. They will gather samples of lunar material and willl deploy scientific experiments which will transmit data about the lunar environment. They will rejoin Collins in the command module for the return trip to Earth.
