Latest Galaxy clusters Stories
Thanks to the presence of a natural “zoom lens” in space, University of Chicago scientists working with NASA’s Hubble Space Telescope have obtained a uniquely close-up look at the brightest gravitationally magnified galaxy yet discovered.
Thanks to the presence of a natural "zoom lens" in space, NASA's Hubble Space Telescope got a uniquely close-up look at the brightest "magnified" galaxy yet discovered.
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.
Astronomy & Astrophysics is publishing a new statistical study of the so-called 'ultra-compact dwarf galaxies' (UCDs), which are still mysterious objects.
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.
The NASA/ESA Hubble Space Telescope has been used to make an image of galaxy cluster MACS J1206.2-0847.
Astronomers are puzzled by the announcement that the masses of the largest objects in the Universe appear to depend on which method is used to weigh them.
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 IC 342/Maffei Group (also known as the IC 342 Group or the Maffei 1 Group) is the closest group of galaxies to the Local Group. The member galaxies are both concentrated around the two brightest galaxies of IC 342 and Maffei 1. The group can therefore be described as a binary group. Along with many others the group is located in the Virgo Supercluster.
The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...
The Centaurus A/M83, divided into subgroup Cen A and M83, is a complex group of galaxies located within Hydra, Centaurus, and Virgo constellations. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered around Centaurus A, a nearby radio galaxy. The M83 Subgroup, at a distance of 14.9 Mly (4.56 Mpc), is centered around the Messier 83 (M83), a face-on spiral galaxy. Due to the physical closeness of both subgroups they are sometimes identified as two groups sometimes as one....
The Bullet Cluster is made up of two colliding clusters galaxies. According to a 2006 study, the Bullet Cluster also shows the best evidence for the existence of Dark Matter. From observations of galaxy cluster collisions it has been found that many show displacement between their center of visible matter and their gravitational potential. Each component, stars, gas, and dark matter, within a cluster pair behaves differently during a collision allowing for each to be studied separately....
