Astronomy Picture of the Day

                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: This floating ring is the size of a galaxy. In fact, it is a
galaxy -- or at least part of one: the photogenic Sombrero Galaxy [9] , one of
the largest galaxies in the nearby Virgo Cluster of Galaxies [10] . The dark
band of dust [11]  that obscures the mid-section of the Sombrero Galaxy [12]
in optical light actually glows brightly in infrared light. The featured image
[13] , digitally sharpened, shows the infrared [14] glow, recently recorded by
the orbiting Spitzer Space Telescope [15] , superposed in false-color on an
existing [16]  image taken by NASA's Hubble Space Telescope [17] in optical
light. The Sombrero [18] Galaxy, also known as M104 [19] , spans about 50,000
light years [20]  across and lies 28 million light years away. M104 [21] can
be seen with a small telescope in the direction of the constellation Virgo
[22] .
