Fermi Telescope Turns to Dark Matter Search
2013-01-21 10:58:25

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online For much of the last century, scientists have been searching for a mysterious substance thought to make up about 85 percent of the total mass of the Universe. Without it, galactic rotation curves, galaxy interactions and the very structure of the Universe are inconsistent with our knowledge of physics. Yet, this so-called dark matter remains elusive. One reason researchers have had such a difficult time finding and...

Galactic Superwinds Power Up Gas Clouds In M82
2013-01-19 08:00:41

redOrbit Staff & Wire Reports - Your Universe Online Shockwaves originating from the central starburst region of galaxy Messier 82 (M82) are most likely the source of bright clouds within a “cap” of gas clouds located some 40,000 light years away, astronomers have discovered. Kyoto University´s Dr. Kazuya Matsubayshi and an international team of colleagues observed the nearby starburst galaxy, which is located approximately 12 million light-years away in the...

New Book is a Trove of Incisive Insights on the Evolution of the Universe QUEBEC (PRWEB) January 15, 2013 The Big Bang theory is the prevailing paradigm in cosmology. In his new book, “Bright Hole Cosmos: and Multibang Dynamics”, author Andre Trepanier explores this cosmological model as he leads the way to a fascinating journey in the understanding of the evolution of the universe. Trepanier´s goal for writing his groundbreaking treatise is to challenge some of the main...

Dense Cloud Defies Rules Of Star Formation
2013-01-13 09:53:05

redOrbit Staff & Wire Reports — Your Universe Online An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars, astronomers at the California Institute of Technology (Caltech) have discovered, and that behavior has them puzzled as it appears to defy the rules of star formation. The cloud, which the researchers have named G0.253+0.016, is located in the vicinity of a supermassive black hole three millions times as massive as...

New Dwarf Galaxy Found With Possible Protogalaxy
2013-01-12 08:38:48

redOrbit Staff & Wire Reports — Your Universe Online Through detailed study of the constellation Ursa Major, astronomers have reportedly found two new clouds of hydrogen gas, one which is a faint dwarf galaxy, and the other which could be a proto dwarf galaxy that has not yet had a chance to form any stars. The research team, led by Case Western Reserve University astronomy professor Chris Mihos, have dubbed the gas clouds — which are formally named G1425+5235 and...

Evidence Of Gas Flow As Galactic Fuel Found
2013-01-12 08:28:26

redOrbit Staff & Wire Reports — Your Universe Online Thanks to observations obtained using the Hubble Space Telescope, researchers have discovered direct, empirical evidence of the existence of gas flows that are consumed by galaxies as fuel. A team led by Nicolas Lehner, research associate professor at the University of Notre Dame, studied data collected by the telescope´s two ultraviolet spectrographs, the Cosmic Origins Spectrograph and the Space Telescope Imaging...

Astronomers Discover Structure 4 Billion Light Years Across - Largest Known In Universe
2013-01-11 13:29:21

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have reportedly discovered the largest known structure in the universe — a formation so massive it would take a vehicle that was moving at light speed roughly four billion light years to cross it, the Royal Astronomical Society (RAS) announced on Thursday. The structure is a large quasar group (LQG), or a formation that contains the nuclei of galaxies from the earliest days of the universe´s existence. These...

Spiral Galaxy Is The Largest Ever Measured
2013-01-11 11:38:51

redOrbit Staff & Wire Reports - Your Universe Online While searching for data looking for star-forming regions around a galaxy located more than 200 million light years away, researchers have accidentally discovered that it is, in fact, the largest known spiral galaxy in the entire universe. As reported Friday by BBC News reporter Jason Palmer, a research assistant from NASA´s Goddard Space Flight Center and colleagues from the Catholic University of America (CUA), the...

WASHINGTON, Jan. 10, 2013 /PRNewswire-USNewswire/ -- The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest-known spiral, based on archival data from NASA's Galaxy Evolution Explorer (GALEX) mission. GALEX has since been loaned to the California Institute of Technology in Pasadena, Calif. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO)...

Milky Way Star Formation Survey Yields Surprising Results

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...
