Giant Gas Cloud Magnetic Shield Milky Way
2013-11-01 10:13:00

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have discovered a magnetic field deep within the Smith Cloud’s interior that may protect the giant galactic streamer of hydrogen gas during its projected collision with the Milky Way galaxy. The discovery, which was made using the Karl G. Jansky Very Large Array (VLA) and Robert C. Byrd Green Bank Telescope (GBT), could help explain how so-called high velocity clouds (HVCs) remain mostly intact during their mergers with...

Virtual Observatory Study Explains How Black Holes Get So Massive
2013-10-17 12:57:02

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using a "Virtual Observatory" set out to study "fat" black holes that grow up to more than one million solar masses. Some massive black holes are observed as active galactic nuclei (AGN), which attract surrounding gas and release huge amounts of energy. The team collected the data on more than 10,000 AGN whose black hole mass had already been measured by spectroscopic observation. Scientists have wondered exactly how a...

Petal-like Shells And Strange Star Clusters
2013-10-10 11:08:51

[ Watch The Video: Zooming in on PGC 6240 ] [ Watch The Video: Panning across PGC 6240 ] NASA/ESA Hubble Space Telescope PGC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright center. Some of these shells are packed close to the center of the galaxy, while others are flung further out into space. Several wisps of material have been thrown so far that they appear to be almost detached from the galaxy altogether....

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...
