The FIRE project at Caltech has revealed insight into the mismatch between models and reality of galactic masses.

ESA Confirms Inside Out Model Milky Way
2014-01-20 11:40:56

New research from the Gaia-ESO project confirmed previous theories on the inside-out development of the Milky Way, which holds that the inner regions of the galaxy’s disc were the first to form.

ESA Releases Hubble Image Of Messier 83, A Galaxy With Two Hearts
2014-01-10 06:45:29

The Hubble Space Telescope has revealed a new image of the galaxy Messier 83, which has hosted a large number of supernova explosions and is believed to have a double nucleus at its core.

Hubble Detects Faintest-Ever Early Universe Galaxies
2014-01-08 04:44:58

Using the Hubble Space Telescope, a team of researchers has discovered the smallest, faintest and most numerous galaxies ever discovered in the remote universe, according to research presented Tuesday at the annual meeting of the American Astronomical Society in Washington DC.

Study Of Massive Stars Shows Milky Way's Missing Arms
2013-12-17 08:54:09

A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms.

Milky Way Seen More Clearly Than Ever Thanks To New 3D Map Of The Stars
2013-11-29 04:10:22

The Milky Way galaxy recently got a little easier to understand. A group of astronomers created a new 3D map of the stars that reside in the center of the Milky Way which shows, more clearly than ever, the bulge located at the core of our galaxy.

Ancient Brown Dwarfs

New research has found the two oldest brown dwarfs in the galaxy, and they have a somewhat unexpected property: they move extremely fast.

Three Primordial Galaxies Found Merging Near ‘Cosmic Dawn’
2013-11-21 13:36:25

A team using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope and NASA’s Hubble Space Telescope discovered three infant galaxies merging inside a giant bubble of hot ionized gas.

Cosmic Deception: One Galaxy Is Actually Two

The edge-on spiral galaxy UGC 10288 appeared to be a single object in previous observations. However, new detailed radio data revealed that the large perpendicular extension of UGC 10288's halo is really a distant background galaxy with radio jets.

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 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...

The Local Group, compromising more than 30 galaxies (including dwarf galaxies and the Milky Way), is a group of galaxies with a gravitational center located somewhere between the Milky Way and the Andromeda Galaxy. With a binary (dumbbell) shape and a total mass of (1.29 ± 0.14) × 1012M the Local group covers a 10 million light-year diameter. The local group is part of the Virgo Supercluster. The two largest galaxies in the group are the Milky Way and the Andromeda both Spiral...

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...
