Dark Matter Evidence From Galaxy Cluster Abell 1689
2013-09-13 03:56:51

Astronomers studying a new image of the massive galaxy cluster Abell 1689 have revealed the largest known population of globular clusters to date, NASA reported on Thursday.

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.

Mapping Location Of Galactic Clouds

Astronomers using the Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born.

New Theory Explains Expansion Of Universe
2013-09-10 08:47:37

Scientists have proposed a groundbreaking new theory to explain the discrepancies between different methods for measuring the expansion of the universe.

Bizarre Alignment Observed In Butterfly-Shaped Nebulae
2013-09-04 08:57:07

Planetary nebulae occur in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. These nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape.

Modified Gravity Theory Predicts Galaxy Dynamics
2013-08-29 10:22:45

Observational of distant galaxies suggests one of two possibilities: either these galaxies contain significantly more mass than what is seen, or our physical understanding of gravity is flawed.

ALMA Workers Strike

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

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 two Magellanic Clouds (or Nubeculae Magellani), composed of the Large Megellanic Cloud and the Small Magellanic Cloud, are irregular dwarf galaxies visible in the southern hemisphere. They are members of our Local Group and orbit the Milky Way galaxy. Persian astronomer Al Sufi, in 964, was the first to have written anything about the Magellanic Clouds proving they have been known since early time amongst the Middle East peoples. Sufi, in his Book of Fixed Stars, calls the clouds...

The M96 Group (also known as the Leo I Group), one of many in the Virgo Supercluster, is located within the Leo constellation and contains between 8 and 24 galaxies, including three Messier objects. The Leo Triplet, which is physically near M96 Group, and M96 may actually be separate parts of a much larger group.

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...
