Milky Way Seen More Clearly Than Ever Thanks To New 3D Map Of The Stars
2013-11-29 04:10:22

Alan McStravick for redOrbit.com - Your Universe Online The Milky Way galaxy recently got a little easier to understand. A group of astronomers created a new 3D map of the stars that reside in the center of the Milky Way which shows, more clearly than ever, the bulge located at the core of our galaxy. Prior to this new representation it was widely believed the stars in the core orbited in a sort of banana shape. However, scientists, publishing this week in the journal Monthly Notices of...

Giant Gas Cloud Magnetic Shield Milky Way
2013-11-01 10:13:00

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have discovered a magnetic field deep within the Smith Cloud’s interior that may protect the giant galactic streamer of hydrogen gas during its projected collision with the Milky Way galaxy. The discovery, which was made using the Karl G. Jansky Very Large Array (VLA) and Robert C. Byrd Green Bank Telescope (GBT), could help explain how so-called high velocity clouds (HVCs) remain mostly intact during their mergers with...

Petal-like Shells And Strange Star Clusters
2013-10-10 11:08:51

[ Watch The Video: Zooming in on PGC 6240 ] [ Watch The Video: Panning across PGC 6240 ] NASA/ESA Hubble Space Telescope PGC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright center. Some of these shells are packed close to the center of the galaxy, while others are flung further out into space. Several wisps of material have been thrown so far that they appear to be almost detached from the galaxy altogether....

Hostile Weather Balloon At Heart Of Milky Way
2013-10-03 15:13:50

John P. Millis, PhD for redOrbit.com - Your Universe Online We live in relative safety, far away from immense explosions, extreme weather, and chaotic interactions. Of course, I speak of our little corner of the Milky Way, nearly two-thirds of the way out from the galactic center, nestled between two spiral arms. This relatively sparse section of the cosmos stands in stark contracts to the center of the galaxy, where star formation, supernovae and intense space-weather would make life as...

Critical Interplay Discovered Between Cosmic Dust, Magnetic Fields
2013-09-27 10:40:02

Brett Smith for redOrbit.com - Your Universe Online Interstellar magnetic fields can be found throughout the Milky Way and other similar galaxies. They are thought to be a key regulator in star formation and the propagation of cosmic rays. A new study published in The Astrophysical Journal has provided new insights for scientists looking to probe the strength and structure of these magnetic fields, a highly difficult phenomenon to accurately measure. To learn more about interstellar...

USRA-led team finds polarized starlight implicates interstellar dust as host of hydrogen molecule formation, allows tracing magnetic fields in space. Columbia, MD1 (PRWEB) September 25, 2013 In a paper published in the Oct. 1, 2013, issue of The Astrophysical Journal, an integrated team of observers and theoreticians led by USRA astronomer Dr. B-G Andersson, has used telescopes in Spain, Hawaii, Arizona, and New Mexico, to show – for the first time – that intense molecular hydrogen...

Densest Galaxy Discovered
2013-09-24 15:58:52

[ Watch the Video: Hubble Locates Densest Galaxy Ever ] Brett Smith for redOrbit.com - Your Universe Online The distance from our sun to the next closest star, Alpha Centauri, is 25.6 trillion miles. While that may seem far, try to imagine 10,000 stars sitting between the two solar systems, meaning the stars would be spaced about the distance from Earth to Pluto. That’s exactly the scenario in M60-UCD1, a recently discovered 'ultra-compact dwarf galaxy' described in a study by a...

Milky Way In 3D
2013-09-13 11:09:37

John P. Millis, PhD for redOrbit.com - Your Universe Online Because of our location within the Milky Way, it is quite a challenge to get a bird’s eye view of our galaxy. To really get a sense for what our corner of the cosmos really looks like, astronomers have to take detailed measurements of billions of stars and attempt to accurately measure their distance from Earth. Researchers at the Max Planck Institute for Extraterrestrial Physics (MPE) have now created the most detailed model...

Astronomers Find Peanut Sitting In Middle Of Milky Way
2013-09-12 10:32:13

[ Watch the Video: Artist's Impression Of The Milky Way ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing two papers in the journal Astronomy & Astrophysics, say they've found a peanut sitting in the heart of the Milky Way galaxy. Two teams used data from European Southern Observatory (ESO) telescopes to create a three-dimensional map of the central parts of the Milky Way. While crafting the map they found that the inner regions of the galaxy take on a...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
