Densest Galaxy Discovered

A team of NASA scientists have found an 'ultra-compact dwarf galaxy' that may be the densest galaxy ever discovered.

Sleeping Supermassive Black Holes Can Have Periods Of Intense Flare-Ups

Around 2 million years ago, the supermassive black hole at the center of our galaxy erupted in a blaze of glory big enough to leave a residual glow that can still be seen today.

In the Coma cluster of galaxies, enormous arms of hot gas that span at least a half a million light years have been discovered. Scientists say these findings could provide insight into how the Coma cluster has grown to become one of the largest structures in the Universe held together by gravity.

Milky Way In 3D

Researchers at the Max Planck Institute have now created the most detailed 3D model of the inner structure of the Milky Way ever.

Astronomers Find Peanut Sitting In Middle Of Milky Way
2013-09-12 10:32:13

Two teams used data from European Southern Observatory (ESO) telescopes to create a three-dimensional map of the central parts of the Milky Way. While crafting the map they found that the inner regions of the galaxy take on a peanut-like appearance from certain angles.

Clumpy Structure Makes Disk Galaxies Look Alike Over Time
2013-09-12 06:49:36

Researchers at Iowa State University and IBM have identified why virtually all disk galaxies grow out of their irregular, clumped appearance, and why their older stars acquire the same smooth look as they fade from a bright center to a faint edge.

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...
