WASHINGTON, Feb. 18, 2014 /PRNewswire-USNewswire/ -- Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) According to their analysis, the central part of the neighboring galaxy, called the Large Magellanic Cloud (LMC), completes a rotation every 250 million years. It takes our sun the same...

Early Galaxies Formed By Collisions
2014-01-29 14:23:23

Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the Astrophysical Journal say that massive galaxies in the early universe were formed through collisions. Scientists studied galaxies that existed when the universe was just between 1 and 2 billion years old. The smallest of these galaxies contain a few million stars, while the largest can contain several hundred billion stars. The first stars in the universe showed up about 200 million years after the Big...

[ Watch the Video: Galaxy Mergers And Supermassive Black Holes ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the Astrophysical Journal say they have found two merging galaxies have active supermassive black holes. The team conducted infrared observations of the merging galaxies by using the Subaru Telescope. They found that at least one of the supermassive black holes almost always becomes active and luminous by accreting a large amount of...

Astronomer Discovers Hydrogen River Flowing Into Nearby Galaxy

April Flowers for redOrbit.com - Your Universe Online What might be a never-before-seen river of hydrogen flowing through space has been discovered by West Virginia University astronomer, D.J. Pisano, using the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT). A study, published in the Astronomical Journal, reveals that this river is a faint, very tenuous filament of gas, which is streaming into the nearby galaxy, NGC 6946. Understanding this may help...

redOrbit Staff & Wire Reports - Your Universe Online Using NASA’s Chandra X-ray Observatory and a host of other telescopes, astronomers have managed to locate one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming. This black hole, which is located in a galaxy cluster known as RX J1532.9+3021 (or RX J1532 for short), has created gigantic...

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 NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 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 separate.

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...
