Grant From Uwingu Fund Will Help Dark-Sky Save Our Stars
2013-06-03 13:54:35

Lee Rannals for redOrbit.com — Your Universe Online The International Dark-Sky Association (IDA) was recently awarded a grant from the Uwingu Fund in support of the organization's new program called "Save Our Stars." According to IDA, Save Our Stars (SOS) is a program aimed to work with amateur astronomers and other groups to educate about light pollution, provide information about how it can be diminished, and educate about the importance of limiting sky pollution to protect the...

Astronomers Observe Galaxy In Act Of Dying
2013-06-03 13:16:28

Lee Rannals for redOrbit.com — Your Universe Online Astronomers announced at the 222nd American Astronomical Society meeting in Indianapolis that they have observed the first clear example of a galaxy in the act of dying. The team says they saw a bright dwarf galaxy relatively close to Earth's Milky Way that was "trailing fireballs." They said until now, there has been no clear example of this transformation happening. “We think we´re witnessing a critical stage in...

Cold Gas May Fuel Galaxy And Star Formation
2013-05-26 05:49:55

redOrbit Staff & Wire Reports - Your Universe Online As galaxies grow over the course of billions of years, they apparently use the cosmic equivalent of bendy straws to feed on cold gas and gain mass, according to new research published in the May 20 edition of the Astrophysical Journal. The study is based on computer simulations conducted by Kyle Stewart, who is currently with California Baptist University in Riverside but completed most of the research while with NASA´s Jet...

Galaxy Mega Merger Spotted By Herschel And Keck
2013-05-23 04:53:50

Watch the Video: Mega Galaxy Merger ] April Flowers for redOrbit.com - Your Universe Online Around 11 billion years ago, two hungry young galaxies collided and they are now forming a massive galaxy approximately 10 times the size of the Milky Way. The new mega-galaxy, HXMM01, was discovered as part of a UC-Irvine led project conducted with the W.M. Keck Observatory, the Herschel space observatory, and other research facilities around the world. It is extremely rare to capture the...

Solar Twin Revealed By CoRoT
2013-05-20 06:06:03

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Our knowledge of how stars evolve arises out of our survey of billions of stars within and outside of our galaxy. As we piece together the snapshots of these stars of various sizes and masses, at various stages of their evolution, we begin to get a complete picture of how stars are born, live, and die. Of course, stars most similar to our Sun are perhaps the most relevant as they can tell us about our Sun´s past...

Ring Of Fire In Messier 94 Galaxy
2013-05-19 08:20:24

NASA's Jet Propulsion Laboratory Johnny Cash may have preferred this galaxy's burning ring of fire to the one he sang about falling into in his popular song. The "starburst ring" seen at center in red and yellow hues is not the product of love, as in the song, but is instead a frenetic region of star formation. The galaxy, a spiral beauty called Messier 94, is located about 17 million light-years away. In this image from NASA's Spitzer Space Telescope, infrared light is represented in...

Clouds Of Hydrogen Gas Found In Our Galactic Backyard

Watch the video “Intergalactic Clouds Lurk Between Nearby Galaxies" John P. Millis, PhD for redOrbit.com — Your Universe Online As we gaze into space beyond the confines of our own Milky Way, we see a Universe filled with galaxies. But what scientists have come to realize is that the emptiness that spans between these giant pools of stars is not empty at all, but rather is filled with massive amounts of gas. In fact, these gas reservoirs can sometimes outweigh the galaxies...

Sagittarius A Black Hole To Devour Hot Molecular Gas
2013-05-07 12:42:37

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Herschel spacecraft has revealed that the supermassive black hole in the center of our galaxy is about to get a taste of some hot molecular gas. Sagittarius A has a mass of about four million times that of our Sun and sits about 26,000 light-years away from us. It is a few hundred times closer to us than any other galaxy with an active black hole at its center, making it ideal for studying these...

Pinpointing Radio Wave Origins In The Distant Universe
2013-05-01 05:04:41

April Flowers for redOrbit.com - Your Universe Online For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies. This was achieved by more than 50 hours of observations with the ultra-sensitive Karl G. Jansky Very Large Array (VLA). The researchers found that approximately 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores. The remaining 37 percent...

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...
