[ Watch the Video: How Have Barred Spiral Galaxies Evolved Over Time? ] John P. Millis, PhD for redOrbit.com - Your Universe Online There are a number of interesting puzzles in astronomy that have faced significant challenge because the analysis simply requires massive amounts of data and complicated algorithms that demands serious computing power. Luckily, in at least some of these cases, the same algorithms that are a difficult for a computer to execute are relatively easy for our...

Himiko Galaxy's 'Space Blob' Halo Dates Back To The Cosmic Dawn
2014-01-17 08:10:48

redOrbit Staff & Wire Reports - Your Universe Online Questions surrounding the glowing gaseous halo extending from a massive early galaxy that have puzzled astronomers since its discovery in 2009 have finally been answered by research appearing in a recent edition of The Astrophysical Journal. Himiko, a very large and extremely distant galaxy with a gaseous halo extending over 55,000 light years, was first discovered four years ago using the Subaru Telescope located at Hawaii’s...

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

April Flowers for redOrbit.com - Your Universe Online A new image released from the ESA and NASA jointly-operated Hubble Space Telescope features the spiral galaxy Messier 83, also known as the Southern Pinwheel Galaxy. Messier 83, which is one of the largest and closest barred spiral galaxies to us, has hosted a large number of supernova explosions, and is thought to have a double nucleus at its core. The image was released this week at the 223rd meeting of the American Astrophysical...

Quasars Illuminate Swirling Clouds Around Galaxies
2014-01-09 08:49:42

University of Illinois at Urbana-Champaign A new study of light from quasars has provided astronomers with illuminating insights into the swirling clouds of gas that form stars and galaxies, proving that the clouds can shift and change much more quickly than previously thought. Led by University of Illinois at Urbana-Champaign astronomy professor Robert J. Brunner and former graduate student Troy Hacker (now with the U.S. Air Force), the astronomers published their findings in the...

One-Percent Accurate Measurement Of Universe Completed By BOSS

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...
