Green Bean Galaxy, A New Class Of Galaxy
2012-12-05 06:03:50

[ Watch the Video: The Green Bean Galaxy J2240 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the European Space Observatory's Very Large Telescope (VLT) have identified a new galaxy class. The "green bean galaxies" have an unusual appearance, glowing in intense light emitted from the surroundings of monster black holes. The galaxies are amongst the rarest objects in the universe, and in the case of green bean galaxies, the entire galaxy glows, not just...

Astronomers Take Starburst Galaxy Census
2012-12-04 13:02:44

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have taken a census of hundreds of previously unseen starburst galaxies, revealing high star-formation rates across the Universe. The team used the European Space Agency's Herschel space observatory and ground-based W. M. Keck Observatory to make the observation. Starburst galaxies give birth to hundreds of solar masses' worth of stars every year, while galaxies like our Milky Way produce only one Sun-like star per year....

Hubble Image Shows Hercules A
2012-11-29 14:26:18

[ Watch the Video: Hercules A Zoom Sequence ] Lee Rannals for redOrbit.com - Your Universe Online A new Hubble Space Telescope image released today shows off a multi-wavelength view of radio galaxy Hercules A. The image was produced through a collaboration of the Hubble Space Telescope's Wide Field Camera 3, and the upgraded Karl G. Jansky Very Large Array (VLA) radio telescope in New Mexico. The yellowish elliptical galaxy seen in the image is about 1,000 times more massive than...

Massive Black Hole Is A Real Heavyweight
2012-11-29 06:42:37

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have measured the mass of what may be the most massive black hole observed so far by using the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory. The black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent, according to the study published in the journal Nature. NGC 1277 is about 220 million light-years away from Earth, and is just ten percent the size and...

Most Distant Galaxy Record Broken
2012-11-15 22:10:07

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have found the most distant galaxy ever seen in the universe by using NASA's Hubble and Spitzer space telescopes. The newly discovered galaxy, named MACS0647-JD, is only a tiny fraction of the size of our Milky Way galaxy, and is observed at 420 million years after the big bang. MACS0647-JD offers a glimpse into what the universe was like when it was just three percent of its present age of 13.7 billion years old....

WASHINGTON, Nov. 15, 2012 /PRNewswire-USNewswire/ -- By combining the power of NASA's Hubble and Spitzer space telescopes and one of nature's own natural "zoom lenses" in space, astronomers have set a new record for finding the most distant galaxy seen in the universe. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The farthest galaxy appears as a diminutive blob that is only a tiny fraction of the size of our Milky Way galaxy. But it offers a peek back into a time when the...

Chandra X-Ray Observatory Images Star-Making Cluster Cygnus OB2
2012-11-08 09:57:12

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA has released a new image of the Cygnus OB2 star cluster, detailing its structure and evolution. The Milky Way, as well as other galaxies in the universe, are home to numerous young star clusters with hundreds of thousands of hot, massive, young stars known as O and B stars. Cygnus OB2 is one of these clusters that contains no less than 60 O-type stars and upwards of a thousand B-type stars. Using the Chandra X-Ray...

Globular Star Cluster NGC 6362
2012-10-31 06:19:57

[ Video 1 ] | [ Video 2 ] European Southern Observatory Photo Release This colorful view of the globular star cluster NGC 6362 was captured by the Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at ESO´s La Silla Observatory in Chile. This new picture, along with a new image of the central region from the NASA/ESA Hubble Space Telescope, provide the best view of this little-known cluster ever obtained. Globular clusters are mainly composed of tens of thousands of very...

Black Hole Blows Giant Plasma Bubble Like A Child Blowing Bubble Gum
2012-10-29 11:51:02

Michael Harper for redOrbit.com — Your Universe Online The team at ASTRON, the Netherlands Institute for Radio Astronomy, has been pointing their low Frequency Array (or LOFAR) telescope at the sky since 2010, using bands of low frequencies to observe the heavens. With LOFAR, ASTRON is able to look deep into the heavens for signals of galaxies and other far away objects that haven´t yet reached earth. Now, after using a new, international version of LOFAR, called (ILT), the...

Star Stream Serves As Light Snack For Growing Milky Way
2012-10-27 05:56:42

redOrbit Staff & Wire Reports - Your Universe Online The Milky Way apparently has one voracious appetite, as researchers from a prominent American university have discovered our home galaxy slowly consuming the remnants of an ancient star cluster. Astronomers from Yale University used the Sloan Digital Sky Survey to locate a stream of stars being slowly ingested by the galaxy. While researchers have previously discovered evidence that the Milky Way has gobbled up dwarf galaxies,...

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 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...

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...

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...
