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...

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...

Milky Way Star Formation Survey Yields Surprising Results
2013-01-10 09:33:34

[ Watch the Video: HII Region Discovery Survey ] redOrbit Staff & Wire Reports - Your Universe Online A new survey of the Milky Way has uncovered hundreds of previously-unknown regions of massive star formation, including some of the most distant located to date in the galaxy, researchers revealed on Wednesday. Using the National Science Foundation's (NSF) Green Bank Telescope (GBT) in West Virginia and the Arecibo Observatory Telescope in Puerto Rico, as well as data from the...

First “Bone” In The Milky Way Discovered At CfA
2013-01-09 11:26:21

redOrbit Staff & Wire Reports - Your Universe Online Astronomers affiliated with the Harvard-Smithsonian Center for Astrophysics (CfA) have discovered a new structure in the Milky Way — a lengthy tendril comprised of dust and gas. The tendril — or “bone” as they refer to it — is long and slender, drawing comparisons to the fibula, or calf bone. In a statement, lead author Alyssa Goodman stated that this marks the first time that scientists have been...

Starbursts Caught Near The Milky Way's Galactic Center
2013-01-09 10:47:01

redOrbit Staff & Wire Reports - Your Universe Online Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way, NASA officials reported on Tuesday. According to the US space agency, our galaxy´s nucleus is home to a black hole with four million times the mass of the sun. It is orbited by a large disk of dust and gas, and holds...

New Methods Realized For Imaging The Center Of The Milky Way
2013-01-08 14:22:37

Rayshell Clapper for redOrbit.com - Your Universe Online Astronomers may now have a way to image the center of the Milky Way galaxy, which has posed problems to scientists trying to image all of its exotic features. Soon they may be able to learn more about the features of the center of the Milky Way and learn more about where they are located in the galaxy by use of radio waves. Prior to the discovery of radio waves, astronomers primarily used optical waves like the X-ray and infrared...

Black Hole Caught Belching In Neighboring Galaxy
2013-01-08 08:36:30

April Flowers for redOrbit.com - Your Universe Online A team of scientists conducting a long-term study of molecules in galaxies gained a tantalizing look at what is likely a powerful belch by a gorging black hole at the center of a changing galaxy. "The discovery was entirely serendipitous. Our observations were spread over a few years, and when we looked at them, we found that one galaxy had changed over that time from being placid and quiescent, to undergoing a hugely energetic...

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...
