... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... January 8, 2007 . ... SENTINEL CORRESPONDENT . Astronomers at UC Santa Cruz have discovered a surprisingly massive halo of bright, old stars around our galactic neighbor Andromeda, pushing the outer limits of the galaxy to 1.5 million light years, and teaching them how spiral galaxies behave. ... Younger stars may be remnants of a galaxy devoured, but older stars could have formed with the birth of the galaxy. ... http://www.santacruzsentinel.com/archive/2007/January/08/local/stories/03local.htm . ...

The galaxy in this picture is literally tearing itself apart to shine as brightly as it does! ... Although this galaxy is a thousand times brighter than our own Milky Way galaxy it s impossible to take a detailed photograph, even with the most powerful telescope because it lies over 12 billion light years away. ...
