The spiral galaxy NGC 4622 lies approximately 111 million light-years away from Earth in the constellation Centaurus. NGC 4622 is an example of a galaxy with leading spiral arms . [ 2 ] Each spiral arm winds away from the center of the galaxy and ends at an outermost tip that "points" in a certain direction (away from the arm).
NGC 4656/57 is a highly warped edge-on [3] barred spiral galaxy located in the local universe 30 million light years away from Earth in the constellation Canes Venatici. [4] This galaxy is sometimes called the Hockey Stick Galaxy or the Crowbar Galaxy. Its unusual shape is thought to be due to an interaction between NGC 4656, NGC 4631, and NGC ...

A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars surrounded by a rotating disc of younger Population I stars. A spiral galaxy maintains its spiral arms due to density wave theory.
A preliminary description of the three areas of this diagram was made in 2003 by Eric F. Bell et al. from the COMBO-17 survey [1] that clarified the bimodal distribution of red and blue galaxies as seen in the analysis of Sloan Digital Sky Survey data [2] and even in de Vaucouleurs's 1961 analyses of galaxy morphology.
Though they do not appear in Andromeda, both dwarf galaxies are gravitationally bound to the far larger Andromeda Galaxy. [42] IC 10 is an irregular galaxy that is the closest known starburst galaxy and the only one in the Local Group of galaxies. [43] Cassiopeia also contains part of the closest galaxy group to our Local Group, the IC 342 ...
