John P. Millis, Ph.D. for redOrbit.com - Your Universe Online While images of the Milky Way or Andromeda galaxies may dominate our mind’s image of what a galaxy looks like, the fact is that the largest objects in the Universe come in all shapes and sizes. In fact, most galaxies in the cosmos are known as dwarf galaxies. These systems are, as the name might suggest, smaller versions of the elliptical, spiral, and irregular galaxies that usually spring to mind. In many cases, these...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As astronomers have sought to understand the formation and evolution of galaxies, a handful of simple truths have emerged. Despite many questions remaining, we know that galaxies form in clusters, and create interlinked chains and structures that create a spider web across the cosmos. [ Watch the Video: Hubblecast 76: Merging Galaxies And Droplets Of Starbirth ] Because they often move through the Universe in such close...

Distant Galaxy Shows Evidence Of A 'Red And Dead' Future

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When galaxies first form they are dominated by gas that, over time, lays the foundation for stars. As more stars form the gas becomes locked up in stellar objects and their core remnants, such as white dwarfs, neutron stars, and black holes. Eventually, the gas will become depleted, leaving behind a cold dead galaxy. This process, however, can look different for varying galaxy types, and astronomers have been looking to...

[ Watch The Video: A Simulated Dwarf Galaxy 800 Million Years After The Big Bang ] The University of Sheffield New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way. The supermassive black holes in the cores of some galaxies drive massive outflows of molecular hydrogen gas. As a result, most of the cold gas is expelled from the galaxies. Since...

April Flowers for redOrbit.com - Your Universe Online Astronomers are hoping to gain a new understanding of how galaxies grow from watching a distant “twin” of the Milky Way as it is swallowing another galaxy. Dr. Caroline Foster of the Australian Astronomical Observatory (AAO) led the team that has been studying NCG 4651, called the Umbrella galaxy for the “parasol” of stars that are all that remain of the galaxy being consumed. Umbrella can be found approximately 62 million...

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 × 1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...

The NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them separate.

The M101 Group, one of many in the Virgo Supercluster, is located in Ursa Major and named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). The group is composed mostly of members that are companions of the Pinwheel Galaxy. The M51 Group and the NGC 5866 Group are M101's closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them...

The M81 Group, containing the well known galaxies Messier 81 and Messier 82, is a group of galaxies within the constellation Ursa Major. Along with Messier 81 and 82 are several other galaxies with apparent brightness. The center, located at an approximate distance of 3.6 Mpc, is one of the nearest groups to the Local Group. The total estimated mass of the group is (1.03 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
