Magellanic Stream Origins Discovered By Hubble
2013-08-08 15:15:43

John P. Millis, PhD for redOrbit.com - Your Universe Online Stretching almost halfway around the Milky Way galaxy, the Magellanic Stream is a ribbon of gas that has puzzled astronomers for decades. Now, using data from the Hubble Space Telescope (HST), astronomers now believe that they have nailed down its source. Visible from the southern hemisphere, the dwarf galaxies known as the large and small Magellanic Clouds - the LMC and SMC, respectively - are two of our nearest galactic...

WASHINGTON, Aug. 8, 2013 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have solved a 40-year mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) The Large and Small Magellanic Clouds, two dwarf galaxies orbiting the Milky Way, are at the head of the gaseous stream. Since the stream's discovery by radio telescopes in the...

SOFIA AIrborne Telescope Heading South To New Zealand
2013-07-18 18:30:35

Lee Rannals for redOrbit.com - Your Universe Online NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope has moved south to New Zealand for the next two weeks to take advantage of the Southern Hemisphere's orientation. The space agency said the airborne observatory would be utilizing its southern position to take advantage of studying celestial objects that are difficult or impossible to see in the northern sky. SOFIA is a telescope attached to a modified Boeing...

European Southern Observatory Astronomers Capture New Image Of 47 Tucanae
2013-01-10 15:33:15

[Watch the Video: A close look at the globular star cluster 47 Tucanae] redOrbit Staff & Wire Reports - Your Universe Online Using their Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers at the European Southern Observatory (ESO) have managed to capture a new infrared image of 47 Tucanae, the second most massive globular cluster in the galaxy. The picture, which was released by the ESO on Thursday, depicts the cluster “in striking detail,” the...

April Flowers for redOrbit.com — Your Universe Online A team of astrophysicists from the Center for Astrophysics at the University of Notre Dame are exploring a discrepancy between the amount of lithium predicted by the standard models of elemental production during the Big Bang and the amount of lithium observed in the gas of the Small Magellanic Cloud. The Small Magellanic Cloud is a dwarf galaxy with a diameter of about 7,000 light-years.  It contains several hundred...

Milky Way Not The Only Galaxy On The Block

Lee Rannals for redOrbit.com - Your Universe Online A new sky survey has revealed that our Milky Way galaxy may not be as special as scientists had previously thought. The Milky Way is a fairly common type of galaxy, but being paired up with neighbors like the Magellanic Clouds makes it stick out above the rest, so much so that astronomers thought it could be a one of a kind occurrence. However, astronomer Dr. Aaron Robotham burst everyone's bubble when searching for groups of...

The Magellanic Stream is an arc of hydrogen gas spanning more than 100 degrees of the sky as it trails behind the Milky Way's neighbor galaxies, the Large and Small Magellanic Clouds. Our home galaxy, the Milky Way, has long been thought to be the dominant gravitational force in forming the Stream by pulling gas from the Clouds. A new computer simulation by Gurtina Besla (Harvard-Smithsonian Center for Astrophysics) and her colleagues now shows, however, that the Magellanic Stream resulted...

A giant stream of gas flowing from neighbor galaxies around our own Milky Way is much longer and older than previously thought, astronomers have discovered. The new revelations provide a fresh insight on what started the gaseous intergalactic streamer. The astronomers used the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) to fill important gaps in the picture of gas streaming outward from the Magellanic Clouds. The first evidence of such a flow, named the Magellanic...

Like a fork piercing a fried egg, a giant finger of hydrogen gas is poking through our Milky Way Galaxy from outside, astronomers using CSIRO radio telescopes at Parkes and Narrabri have found.The location of the intrusion may give a crucial clue to the fate of the little galaxies the gas flows from, the Large and Small Magellanic Clouds."We're thrilled because we can determine exactly where this gas is ploughing into the Milky Way "“ it's usually extremely hard to get distances to such...

Cambridge, MA - The Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are two of the Milky Way's closest neighboring galaxies. A stunning sight in the southern hemisphere, they were named after Ferdinand Magellan, who explored those waters in the 16th century. For hundreds of years, these galaxies were considered satellites of the Milky Way, gravitationally bound to our home galaxy. New research by Gurtina Besla (Harvard-Smithsonian Center for Astrophysics) and her colleagues...

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...
