Spitzer Finds New Stars At Edge Of Milky Way
2013-06-06 09:48:09

New images from NASA’s Spitzer Space Telescope reveal blooming stars at the fringe of the Milky Way galaxy, far from its crowded core.

Astronomers Observe Galaxy In Act Of Dying
2013-06-03 13:16:28

Astronomers announced at the 222nd American Astronomical Society meeting in Indianapolis that they have observed the first clear example of a galaxy in the act of dying.

Galaxy Mega Merger Spotted By Herschel And Keck
2013-05-23 04:53:50

Around 11 billion years ago, two hungry young galaxies collided and they are now forming a massive galaxy approximately 10 times the size of the Milky Way. The new mega-galaxy, HXMM01, was discovered as part of a UC-Irvine led project conducted with the W.M. Keck Observatory, the Herschel space observatory, and other research facilities around the world.

Clouds Of Hydrogen Gas Found In Our Galactic Backyard

Using the NSF's Green Bank Telescope, astronomers have discovered large clouds of hydrogen lurking in our galactic neighborhood.

Hubble Provides Evidence That Galaxies Do Not Confine Starbursts
2013-04-25 08:22:14

When galaxies form new stars, they can create frantic episodes of activity known as starbursts. Scientists using the Hubble Space Telescope say these events can affect galactic gas at distances of up to 20 times greater than the visible size of the galaxy.

Galaxy Forms New Stars With Extreme Efficiency

Efficiency experts and green technology proponents can now look to the heavens for inspiration, as astronomers have identified a galaxy that forms stars at almost 100 percent efficiency.

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.

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...
