Galaxy cluster MCS J0416.1–2403
2014-07-26 03:30:45

ESA/Hubble Information Center Stunning new observations from Frontier Fields Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing program, the map shows the amount and distribution of mass within MCS J0416.1–2403, a massive galaxy cluster found to be 160 trillion times the mass of the Sun. The detail in this mass map was made possible thanks...

Bullet Group
2014-06-14 03:00:23

ESA Galaxies are not as isolated as they at first glance may seem; on a cosmic scale they congregate in clumps along with dark matter and hot gas. The colorful blob in this new composite image, based on data from several telescopes including ESA's XMM-Newton, is the group of galaxies known as the Bullet Group. Its components appear to be clearly separated, with the hot gas partitioned from the rest of the mass within the group. This is the smallest object ever found to show such an effect,...

redOrbit Staff & Wire Reports - Your Universe Online Many of the oldest and most massive galaxies reside together in enormous structures known as clusters, and now a team of astronomers has confirmed the existence of an unusually distant galaxy cluster – a group of 19 galaxies located at precisely the same distance of 9.9 billion light years. In research appearing in The Astrophysical Journal, Andrew Newman of the Carnegie Institution for Science and his colleagues explain how...

Monster Of A Galaxy Cluster - El Gordo Lives Up To Its Nickname
2014-04-04 07:03:29

April Flowers for redOrbit.com - Your Universe Online | Source Material Provided by NASA El Gordo is Spanish for "the fat one," and the nickname of the largest galaxy known galaxy cluster in the distant universe, ACT-CLJ0102-4915. A new study from NASA's Hubble Space Telescope reveals that the galaxy cluster, which is 9.7 billion light-years from Earth, definitely lives up to its nickname. According to a NASA report, a team of astronomers measured how much the cluster's gravity warps...

WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname -- El Gordo (Spanish for "the fat one"). http://photos.prnewswire.com/prnvar/20081007/38461LOGO By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to...

Astronomers Use Cluster Of Galaxies As A Giant Telescope

[ Watch the Video: A Telescope Bigger Than A Galaxy ] April Flowers for redOrbit.com - Your Universe Online On a starry night, around 400 years ago, Galileo turned his primitive spyglass toward the sky. In just a few nights, he learned more about the stars than all of the scientists and philosophers before him, combined. Since those historic nights, astronomers have operated under a single imperative: make bigger telescopes. The power of optics has grown a million-fold as the 21st...

Blood And Guts Spilled By Spiral Galaxy

[ Watch The Video: Zooming in on ESO 137-001 ] ESA/Hubble This new Hubble image shows ESO 137-001, a galaxy located in the southern constellation of Triangulum Australe (The Southern Triangle) — a delicate and beautiful spiral galaxy, but with a secret. This image not only captures the galaxy and its backdrop in stunning detail, but also something more dramatic — intense blue streaks streaming outwards from the galaxy, seen shining brightly in ultraviolet light. These...

Frontier Fields Project Locates One Of The Most Distant Galaxies Ever

[ Watch the Video: Abell2744 Y1 Is The Most Distant Galaxy Discovered ] redOrbit Staff & Wire Reports – Your Universe Online By analyzing data collected by the Hubble and Spitzer Space Telescopes, an international team of astronomers have discovered what could be one of the most distant galaxies ever discovered, existing at a time when the universe was no more than approximately 650 million years old. The galaxy, which is known as Abell2744 Y1, is roughly 30 times smaller than...

ultramassive black hole
2014-01-24 04:20:25

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...

Kinetic Sunyaev-Zel'dovich Effect Observed In Individual Object For The First Time
2014-01-17 11:14:32

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) report in a recent study that they have observed a change in an individual object’s cosmic microwave background radiation resulting from its interaction with massive moving objects for the first time ever. According to the recently-published paper in The Astrophysical Journal, this phenomenon, which is known as the...

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 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....
