Researchers from the University of Nevada, Reno and the University of Victoria have found a new use for the Global Positioning System — the direct detection and measuring of dark matter.
A new study has found that massive black holes which emit radio-frequency-emitting particles at near-light speed may possibly be able to block the formation of new stars in older galaxies.
Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood.
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
Using a new mapping technique that takes into account the motions of nearby galaxies, researchers have discovered that the Milky Way resides on the outer edge of a massive, previously undetected supercluster of galaxies that they have dubbed Laniakea.
Using a battery of observatories that included the ALMA and the Hubble Space Telescope, astronomers have obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age.
A massive new elliptical galaxy unexpectedly discovered using NASA’s Hubble Space Telescope is the most distant lensing galaxy ever discovered, officials from the US space agency confirmed in a statement Thursday.
WASHINGTON, July 31, 2014 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass.
For the first time, astronomers have been able to precisely measure the mass of the Milky Way, and have discovered that our solar system's home is actually smaller than previously believed.
Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before.
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...
