... 2014 November 5 . NGC 4762: A Galaxy on the Edge . Image Credit: ESA/Hubble NASA . ... The image from the Hubble Space Telescope is a spectacular visual reminder of just how thin disk galaxies can be. NGC 4762, a galaxy in the nearby Virgo Cluster of Galaxies , is so thin that it is actually difficult to determine what type of disk galaxy it is. ... Near NGC 4762 's center is a slight bulge of stars, while many background galaxies are visible far in the distance. ... About APOD | ...

... NGC 4452: An Extremely Thin Galaxy . ... In one of the more precise alignments known in the universe, what is pictured above is actually a disk galaxy being seen almost perfectly edge on. The image from the Hubble Space Telescope is a spectacular visual reminder of just how thin disk galaxies can be. NGC 4452, a galaxy in the nearby Virgo Cluster of Galaxies , is so thin that it is actually difficult to determine what type of disk galaxy it is. ... NGC 4565: Galaxy on Edge . ...

Stellar density and bar strength should affect the temperatures of the cool (T ~ 20-30 K) dust component in the inner regions of galaxies, which implies that the ratio of temperatures in the circumnuclear regions to the disk should depend on Hubble type. ... The strong radiation field in the high stellar density of a galactic bulge tends to heat the cool dust component to higher temperatures, at least in early-type spirals with relatively large bulges, especially when paired with a strong bar. ...
