Giant Gas Cloud Spotted By Telescope On Antarctica's Ridge A
2014-02-21 08:19:35

Deborah Smith, University of New South Wales Using a telescope installed at the driest place on earth - Ridge A in Antarctica – a UNSW-led team of researchers has identified a giant gas cloud which appears to be in an early stage of formation. Giant clouds of molecular gas – the most massive objects in our galaxy – are the birthplaces of stars. "This newly discovered gas cloud is shaped like a very long filament, about 200 light years in extent and ten light years across, with...

Large Magellanic Cloud Completes One Rotation Every 250M Years

[ Watch the Video: Large Magellanic Cloud Rotation Cycle ] Lee Rannals for redOrbit.com - Your Universe Online Scientists using NASA's Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years from Earth. "Studying this nearby galaxy by tracking the stars' movements gives us a...

WASHINGTON, Feb. 18, 2014 /PRNewswire-USNewswire/ -- Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) According to their analysis, the central part of the neighboring galaxy, called the Large Magellanic Cloud (LMC), completes a rotation every 250 million years. It takes our sun the same...

ESA's Gaia Mission Is Beginning To See Things More Clearly
2014-02-06 13:37:15

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) billion-star surveyor mission is slowly beginning to see more clearly. ESA’s Gaia launched on December 19, 2013, and since then it has been preparing for its mission to gather loads of data on stars that surround us. Gaia took a test image of a dense cluster of stars in the Large Magellanic Cloud as part of a “fine tuning” test to get the spacecraft into focus. The new image is allowing ESA...

ultramassive black hole
2014-01-24 04:20:25

redOrbit Staff & Wire Reports - Your Universe Online Using NASA’s Chandra X-ray Observatory and a host of other telescopes, astronomers have managed to locate one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming. This black hole, which is located in a galaxy cluster known as RX J1532.9+3021 (or RX J1532 for short), has created gigantic...

ESA Confirms Inside Out Model Milky Way
2014-01-20 11:40:56

[ Watch the Video: Inside-out Formation Of The Milky Way ] Brett Smith for redOrbit.com - Your Universe Online New research from the European Space Agency's (ESA) Gaia-ESO project has confirmed previous theories on the inside-out development of the Milky Way, with the inner regions of the galaxy’s disc being the first to form. According to their report in the astronomical database Astro-ph, the study researchers reached their conclusions using observations taken with the 8-meter...

Hypervelocity Stars Escape Galaxy
2014-01-10 08:44:12

April Flowers for redOrbit.com - Your Universe Online A surprising new class of hypervelocity stars has been discovered by an international team of astronomers. These solitary stars are moving fast enough to escape the gravitational grasp of the Milky Way galaxy, according to a study presented at the annual meeting of the American Astronomical Society. The findings were also published in the Astrophysical Journal. "These new hypervelocity stars are very different from the ones that...

World Premiere Of Planetarium Show 'Journey To A Billion Suns'
2014-01-08 11:12:27

[ Watch The Video: Journey to a Billion Suns Trailer ] ESA A new planetarium show, Journey to a billion Suns, premieres today in Hamburg, Germany, to tell the fascinating story of mapping the Milky Way, from ancient times to ESA’s recently launched Gaia mission. The 45-minute, 360 degree full-dome planetarium spectacular was produced by Stargarten in cooperation with ESA and planetariums across Europe. Gaia was launched on 19 December and will soon start its five-year...

Study Of Massive Stars Shows Milky Way's Missing Arms
2013-12-17 08:54:09

University of Leeds A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms. The new research, which is published online today [17 December] in the Monthly Notices of the Royal Astronomical Society, is part of the RMS Survey, which was launched by academics at the University of Leeds. Astronomers cannot see what our Galaxy, which is called the...

Spitzer's Citizen Science Zoo Displays New Animals
2013-12-17 08:17:13

NASA's Jet Propulsion Laboratory Since 2010, about 50,000 volunteers have taken to their computers to help astronomers catalog star-blown bubbles captured in images from NASA's Spitzer Space Telescope. Their efforts resulted in several scientific papers, and a deeper understanding of our Milky Way galaxy and its frothy star-forming clouds. Now, an updated version of the campaign, called the Milky Way Project, is releasing more images with a whole new set of "animals" to track in the...

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...
