Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Lee Rannals for redOrbit.com — Your Universe Online Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old. The team wrote in the journal Nature that HFLS3 sits at about 12.8 billion light-years from Earth. They said the distant galaxy is producing about 3,000 Suns per year, which is more than 2,000 times that of our own Milky Way galaxy. "This is the...

Blue Supergiant Star Born In The Wild Discovered
2013-04-11 15:09:53

Subaru Telescope A duo of astronomers, Dr. Youichi Ohyama (Institute of Astronomy and Astrophysics, Academia Sinica or ASIAA, Taiwan) and Dr. Ananda Hota (UM-DAE Centre for Excellence in the Basic Sciences or CBS, India), has discovered a Blue Supergiant star located far beyond our Milky Way Galaxy in the constellation Virgo. Over fifty-five million years ago, it emerged in an extremely wild environment, surrounded by intensely hot plasma (a million degrees centigrade) and amidst raging...

Scientists Discover The Earliest Known Starburst Galaxies In The Universe
2013-04-05 15:32:28

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers announced it has found some of the Universe´s earliest starburst galaxies, essentially young energetic clusters of cosmic gas and dust that form stars at an alarming rate. The discoveries, which were detailed in reports published in Nature and the Astrophysical Journal, were made using the newly inaugurated Atacama Large Millimeter/submillimeter Array (ALMA) telescope. In its first billions...

Unexpected Star Formation Found Near Massive Black Hole
2013-04-05 10:29:46

Brett Smith for redOrbit.com - Your Universe Online The entire Milky Way galaxy revolves around a supermassive black hole, which is surrounded by a turbulent expanse of space fraught with extreme gravitational forces. Despite the inhospitable nature of this region, a team of American astronomers has found jets of material that typically indicate star formation when found in less tumultuous sections of the universe, according to their report in the Astrophysical Journal Letters....

Probes Of Dark Matter On Galaxy Scales 2013
2013-04-03 19:01:07

Lee Rannals for redOrbit.com — Your Universe Online Scientists are coming together this summer to try and collaborate on solving the mystery of dark matter. Probes of Dark Matter on Galaxy Scales 2013, will be held July 14—19 in Monterey, California. Scientists at the conference will be meeting to discuss their techniques for solving the secrets of dark matter in the universe. “The idea is to bring together people working on different probes of dark matter from...

X-Ray Emissions In Young Metal-Poor Stars Similar To Metal-Rich Stars
2013-04-03 08:10:18

Lawrence LeBlond for redOrbit.com - Your Universe Online Astronomers have found that a region of space known as the Wing has fewer “metals” (elements with more than two protons in the nucleus) compared to most other areas within our own Milky Way galaxy. There are also relatively lower amounts of gas, dust and stars in the Wing compared to the Milky Way. This knowledge makes the Wing an excellent candidate for the study of the life cycle of stars and the gas lying between...

Distant Black Hole Wakes Up For A Snack
2013-04-02 13:51:29

Watch the video "Black Hole Eats Super-Jupiter" Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the European Space Agency's (ESA) Integral space observatory have watched as a black hole woke up to feed on a low-mass object that strayed just a little too close. The team was using the Integral observatory to study a galaxy 47 million light-years away when they noticed a bright X-ray flare coming from another location. "The observation was completely unexpected,...

Hunting High-mass Stars With Herschel Space Observatory
2013-03-27 13:09:59

ESA In this new view of a vast star-forming cloud called W3, ESA´s Herschel space observatory tells the story of how massive stars are born. W3 is a giant molecular cloud containing an enormous stellar nursery, some 6200 light-years away in the Perseus Arm, one of our Milky Way Galaxy´s main spiral arms. Spanning almost 200 light-years, W3 is one of the largest star-formation complexes in the outer Milky Way, hosting the formation of both low- and high-mass stars. The...

Young Supernova Remnant Discovered By NASA’s Swift Satellite
2013-03-16 10:18:20

redOrbit Staff & Wire Reports — Your Universe Online NASA´s Swift space observatory detected the previously undiscovered remains of a supernova during an extensive X-ray survey of the Milky Way, officials from the US space agency announced on Friday. NASA believes the shattered star remains, which have been named G306.3—0.9 after the coordinates of its sky position, are among the youngest-known supernova remnants in the galaxy. “Astronomers have previously...

Methuselah Star Birth Certificate
2013-03-08 08:38:30

April Flowers for redOrbit.com - Your Universe Online The ink is drying on a brand new birth certificate for a star that's been around for a very long time. New calculations using NASA'S Hubble Space Telescope have enabled a group of astronomers to take an important step closer to reconciling the age of this star, and the age of the Universe. "We have found that this is the oldest known star with a well-determined age," said Howard Bond of Pennsylvania State University in University...

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...
