redOrbit Staff & Wire Reports - Your Universe Online 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. Lensing galaxies essentially act as a cosmic magnifying glass, and are large enough that their gravity can bend and distort light in such a way that they can make it easier to detect more distant objects in space....

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. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. http://photos.prnewswire.com/prnvar/20081007/38461LOGO These "lensing" galaxies are so massive that their gravity bends, magnifies, and distorts light from...

redOrbit Staff & Wire Reports - Your Universe Online 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. As reported this month in the journal Monthly Notices of the Royal Astronomical Society, researchers from the University of Edinburgh, the University of British Colombia, Carnegie Mellon University and NRC Herzberg Institute of Astrophysics...

Galaxy cluster MCS J0416.1–2403

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...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online While images of the Milky Way or Andromeda galaxies may dominate our mind’s image of what a galaxy looks like, the fact is that the largest objects in the Universe come in all shapes and sizes. In fact, most galaxies in the cosmos are known as dwarf galaxies. These systems are, as the name might suggest, smaller versions of the elliptical, spiral, and irregular galaxies that usually spring to mind. In many cases, these...

dark matter mystery
2014-06-26 14:13:25

Brett Smith for redOrbit.com - Your Universe Online According to astrophysicists, dark matter is the key to understanding the universe as it comprises 85 percent of all mass found in it and is suspected to have caused the growth of galaxies. In a new study to be presented at the Royal Astronomical Society's National Astronomy Meeting, scientists from that country’s Durham University have found a possible explanation for why some dark matter didn’t form galaxies in the early Universe...

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,...

Neighboring Satellite Dwarf Galaxies Do Not Fit The Standard Model
2014-06-11 07:37:40

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of scientists have found that dwarf satellite galaxies that orbit the Milky Way and neighboring Andromeda galaxy defy the standard model of galaxy formation. As well, recent attempts to fit them into the model have been flawed, raising questions about the accuracy of the standard model of cosmology, which has been the long accepted concept for the origin and evolution of the universe. In a paper to be...

Supernovae Used To Gauge The Power Of Cosmic Lenses
2014-05-02 06:38:10

redOrbit Staff & Wire Reports - Your Universe Online Two teams of astronomers have used the Hubble Space Telescope to observe distant exploding stars, and their research could help determine the power of naturally-occurring “cosmic lenses” than can be used to magnify objects in the far-off universe, NASA officials announced on Thursday. The scientists, who are working independently, have studied three supernovae using the phenomenon of gravitational lensing, which causes 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 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 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
