Latest Large-scale structure of the cosmos Stories
A Naval Research Laboratory scientist is part of a team that has recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light years from Earth.
A UC Davis graduate student who is leading a study of the collision of galaxy clusters 5 billion light years away discussed the team’s findings today, Jan. 10, in a press briefing at the annual meeting of the American Astronomical Society in Austin, Texas.
An extremely hot, massive young galaxy cluster — the largest ever seen in the distant Universe — has been studied by an international team using ESO’s Very Large Telescope along with NASA's Chandra X-ray Observatory and the Atacama Cosmology Telescope.
Astronomers from the University of British Columbia and University of Edinburgh have mapped dark matter on the largest scale ever observed.
Like wine in a glass, vast clouds of hot gas are sloshing back and forth in Abell 2052, a galaxy cluster located about 480 million light years from Earth.
An international group of astronomers has discovered extraordinarily long one-sided gaseous tails in two groups of galaxies that are amongst the longest structures ever observed in such environments.
Two researchers from Observatoire Astronomique de Strasbourg have revealed for the first time the existence of a new signature of the birth of the first stars in our galaxy, the Milky Way.
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 Ã— 1015 Mâ˜‰ 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 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 Â± 0.17) Ã— 1012Mâ˜‰. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
