First “Bone” In The Milky Way Discovered At CfA
2013-01-09 11:26:21

redOrbit Staff & Wire Reports - Your Universe Online Astronomers affiliated with the Harvard-Smithsonian Center for Astrophysics (CfA) have discovered a new structure in the Milky Way — a lengthy tendril comprised of dust and gas. The tendril — or “bone” as they refer to it — is long and slender, drawing comparisons to the fibula, or calf bone. In a statement, lead author Alyssa Goodman stated that this marks the first time that scientists have been...

Stellar Patrons Of The Milky Way Bar Identified By Astronomers
2012-12-19 15:03:31

SDSS-III Forget the restaurant at the end of the Universe – astronomers now have the clearest understanding yet of the bar at the center of the Milky Way. Scientists with the Sloan Digital Sky Survey III (SDSS-III) have announced the discovery of hundreds of stars rapidly moving together in long, looping orbits around the center of our Galaxy. "The best explanation for their orbits is that these stars are part of the Milky Way bar," says David Nidever, a Dean B. McLaughin Fellow...

Astronomers Need Your Help Looking For Space Anomalies
2012-12-19 13:55:27

Lee Rannals for redOrbit.com — Your Universe Online Astronomers are reaching out to the public and asking for a little help in a study to find holes in dust clouds that are threaded throughout our galaxy. By looking at images from the Herschel Space Observatory, combined with those from NASA´s Spitzer satellite, members of the public can join the scientists by helping to distinguish between dense clumps of cold dust and possible holes in these dusty clouds. Dust clouds do...

WASHINGTON, Dec. 10, 2012 /PRNewswire-USNewswire/ -- Using computer simulations, scientists from the NASA Astrobiology Institute team at the University of Hawaii are shedding light on a question that has challenged astronomers for years: What causes wide binary stars? (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) Binary stars are pairs of stars that orbit each other. Wide binary stars are separated by as much as one light-year in their orbits, farther apart than some stellar...

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....

Astronomers Catalogue 84 Million Stars
2012-10-24 05:48:29

[ Watch the Video: Gigapixel View Of Milky Way ] Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) announced this morning that a team of astronomers have catalogued over 84 million stars in the central parts of the Milky Way. This dataset contains more than ten times more stars than previous studies, and is a major step forward for understanding our galaxy. “By observing in detail the myriads of stars surrounding the center of the...

New Details Shed Light On Galaxy Evolution

[WATCH VIDEO: Computer Model Shows a Disk Galaxy´s Life History] Lee Rannals for redOrbit.com — Your Universe Online After a comprehensive study of hundreds of galaxies, astronomers have uncovered a surprising trend in galaxy evolution. The team studied a sample of 544 blue galaxies from the Deep Extragalactic Evolutionary Probe 2 (DEEP2) Redshift Survey, and wrote about their findings in The Astrophysical Journal. "Astronomers thought disk galaxies in the nearby...

Milky Way Larger Than Previously Thought
2012-10-06 07:49:29

redOrbit Staff & Wire Reports — Your Universe Online The mass of the Milky Way is approximately 20% larger than previously believed, scientists from the National Astronomical Observatory of Japan (NAOJ) have discovered. The NAOJ team, led by associate professor Mareki Honma, used measurements from radio telescopes, including Japan's VLBI (Very Long Baseline Interferometry) Exploration of Radio Astrometry or VERA device, to determine that the distance from the sun to the center...

WASHINGTON, Sept. 24, 2012 /PRNewswire-USNewswire/ -- Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years. The estimated mass of the halo is comparable to the mass of all the stars in the galaxy. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) If the size and mass of this gas halo is confirmed, it also could be an explanation for what is...

Planets Can Form In The Center Of Violent, Unstable Galaxies
2012-09-12 14:05:07

April Flowers for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. The center of the Milky Way seems like the last place to form a new planet, inhospitable and violent even. Stars crowd each other, whizzing through space like cars on a rush hour freeway while supernova explosions blast out shock waves and bathe the region in intense...

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...
