The Sombrero Galaxy is seen by the Hale
What happens in the center of this spiral galaxy? Call Sombrero Galaxy for its resemblance to the Mexican sombrero, M104 has a very striking dust lane and bright halo consisting of stars and clusters globular.
The diffuse glow of the extended core of the galaxy is due to the brilliance of billions of old stars.
A careful examination of the galactic bulges shown in shown in making the 200-inch Hale telescope shown above reveals many points of light that actually correspond to globular clusters . The spectacular dust rings of M104 host many younger and brighter stars, and show intricate details astronomers have not yet deciphered.
The real center of the Sombrero glows across the entire electromagnetic spectrum and think that a large black hole lies in its depths.
The light from the Sombrero Galaxy, it takes 50 million years to reach us, is visible with a small telescope pointed toward the constellation of the Virgin (Virgo in Latin).
The Sombrero Galaxy M104 is one of the largest galaxies in the Virgo cluster, located about 28 million light years from Earth. The main view is a composite of photographs taken by the X-ray space observatory Chandra and Hubble and Spitzer space telescopes, whose individual shots appearing in the boxes on the right. The Chandra image (blue) shows hot gas in the galaxy and other sources that belong to or are Hat cosmic background quasars. The Chandra observations show that the diffuse X-ray emission extends to a distance of over 60 thousand light years from the center of that galaxy. In comparison, the galaxy itself covers a range of 50 thousand light-years long. Scientists think that the X-ray extended emission could well be the result of wind emitted primarily by supernovae that have exploded inside the bulb and the galactic disk. The Hubble optical image (green) shows the bulb of starlight partially blocked by a rim of dust, on the grounds that this spiral galaxy is seen edge-on. The very edge of dust glows in the infrared image from Spitzer, which also reveals the central bulge of stars in the galaxy
