Arecibo gas bridge
2014-08-08 06:43:44

Royal Astronomical Society Astronomers and students have found a bridge of atomic hydrogen gas 2.6 million light years long between galaxies 500 million light years away. They detected the gas using the William E. Gordon Telescope at the Arecibo Observatory, a radio astronomy facility of the US National Science Foundation sited in Puerto Rico. The team published their results Thursday in a paper in Monthly Notices of the Royal Astronomical Society. The stream of atomic hydrogen gas is...

Messier 33
2014-08-06 11:14:16

ESO Messier 33, otherwise known as NGC 598, is located about three million light-years away in the small northern constellation of Triangulum (The Triangle). Often known as the Triangulum Galaxy it was observed by the French comet hunter Charles Messier in August 1764, who listed it as number 33 in his famous list of prominent nebulae and star clusters. However, he was not the first to record the spiral galaxy; it was probably first documented by the Sicilian astronomer Giovanni Battista...

Research Finds Numerous Unknown Jets From Planetary Nebulae And Young Stars
2014-08-01 03:48:51

University of Kent For many years astronomers have known that young 'protostars' drive supersonic jets of gas from their north and south poles. However, this is the first time that so many of them have been detected at once. The results come from a five year survey undertaken with the UK Infra-Red Telescope and are expected to prompt significant changes in the understanding of the planetary nebulae population in the Galaxy, as well as the properties of jets ejected from young forming...

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...

Verity Leatherdale, University of Sydney The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The finding, by an international team of astronomers, including Professor Geraint Lewis from the University of Sydney's School of Physics, was announced July 18 in Nature. "Early in 2013 we announced our startling...

Aricebo Observatory Picks Up Mysterious Radio Burst From Beyond The Milky Way
2014-07-11 13:19:30

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Over the last few years the Parkes radio telescope in Australia has detected a handful of short radio bursts emanating from deep space. This was an amazing discovery, except for the fact that no other radio facilities had seen such pulses, leading some to suggest that the instrument was detecting terrestrial signals. But now, the Arecibo radio telescope has made a similar detection that has the astronomical community talking....

Distant Galaxy Shows Evidence Of A 'Red And Dead' Future
2014-07-10 13:45:41

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When galaxies first form they are dominated by gas that, over time, lays the foundation for stars. As more stars form the gas becomes locked up in stellar objects and their core remnants, such as white dwarfs, neutron stars, and black holes. Eventually, the gas will become depleted, leaving behind a cold dead galaxy. This process, however, can look different for varying galaxy types, and astronomers have been looking to...

Solving The Long-standing Mystery Surrounding The Evolution Of Galaxies
2014-07-08 03:29:57

[ Watch The Video: A Simulated Dwarf Galaxy 800 Million Years After The Big Bang ] The University of Sheffield New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way. The supermassive black holes in the cores of some galaxies drive massive outflows of molecular hydrogen gas. As a result, most of the cold gas is expelled from the galaxies. Since...

NASA/JPL Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA's Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory. Herschel is a European Space Agency mission with important NASA contributions. [ Watch the Video: Zooming In On Messier 106 ] Energetic jets, which blast from Messier 106's central black...

Umbrella Galaxy
2014-07-03 04:44:09

April Flowers for redOrbit.com - Your Universe Online Astronomers are hoping to gain a new understanding of how galaxies grow from watching a distant “twin” of the Milky Way as it is swallowing another galaxy. Dr. Caroline Foster of the Australian Astronomical Observatory (AAO) led the team that has been studying NCG 4651, called the Umbrella galaxy for the “parasol” of stars that are all that remain of the galaxy being consumed. Umbrella can be found approximately 62 million...

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 Local Group, compromising more than 30 galaxies (including dwarf galaxies and the Milky Way), is a group of galaxies with a gravitational center located somewhere between the Milky Way and the Andromeda Galaxy. With a binary (dumbbell) shape and a total mass of (1.29 ± 0.14) × 1012M the Local group covers a 10 million light-year diameter. The local group is part of the Virgo Supercluster. The two largest galaxies in the group are the Milky Way and the Andromeda both Spiral...

At a distance of 3.9 Mpc from the Milky Way, the Sculptor Group is one of nearest groups of galaxies to the Local Gropu. Sculptor is made up of a loose group of galaxies near the south galactic pole. The Sculptor Galaxy (NGC 253) and a few other galaxies form a gravitationally-bound core in the center of this group, however, since they are only weakly bound the group may also be described as a filament. There also some other galaxies associated with the group but not gravitationally...
