Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old.

Early Star Forming Galaxies
2013-04-17 05:09:48

Astronomers report in The Astrophysical Journal that they have determined the positions of over 100 of the most fertile star-forming galaxies in the early Universe.

Blue Supergiant Star Born In The Wild Discovered

A duo of astronomers has discovered a Blue Supergiant star located far beyond our Milky Way Galaxy in the constellation Virgo

Scientists Discover The Earliest Known Starburst Galaxies In The Universe
2013-04-05 15:32:28

An international team of researchers announced it has found some of the universe’s earliest starburst galaxies, essentially young energetic clusters of cosmic gas and dust that form stars at an alarming rate.

Probes Of Dark Matter On Galaxy Scales 2013

Scientists are coming together this summer to try and collaborate on solving the mystery of dark matter.

How Spiral Galaxies Get Their Arms
2013-04-03 12:32:19

Astronomers writing in The Astrophysical Journal have answered a few more important questions about how so-called spiral galaxies get their arms.

X-Ray Emissions In Young Metal-Poor Stars Similar To Metal-Rich Stars
2013-04-03 08:10:18

Astronomers have found that a region of space known as the Wing has fewer “metals” (elements with more than two protons in the nucleus) compared to most other areas within our own Milky Way galaxy. There are also relatively lower amounts of gas, dust and stars in the Wing compared to the Milky Way.

Distant Black Hole Wakes Up For A Snack
2013-04-02 13:51:29

Astronomers using the European Space Agency's (ESA) Integral space observatory have watched as a black hole woke up to feed on a low-mass object that strayed just a little too close.

Dazzling New Hubble Pics Of Beloved Spiral Galaxy Messier 77
2013-03-28 09:13:54

A stunning new image of the spiral galaxy Messier 77 captured by the Hubble Space Telescope was released today. The image of one of the most famous and well-studied galaxies highlights the pockets of star formation along its arms.

Hunting High-mass Stars With Herschel Space Observatory

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...
