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. ...

... Figure 3 shows several tails resulting from trap 2-637. ... The solid line shows a simple exponential decay, as described in our idealized model. It appears that the behavior of the bright traps has been relatively constant with time, and the simple exponential decay provides a fairly good fit to the data. ... What about the dark tails seen just above some of the traps? ... For example, the dark tail decay rate for trap 2-337 is only about 3% while the bright tail decay rate is 19%. ...

. Comet ISON continues to brighten. In this image, it appears in the southeastern part of the constellation Leo the Lion. Look carefully around the field and you ll spot several faint galaxies, including one at the very tip of the comet s tail.
