Quasar Pair Captured In Galaxy Collision
Pasadena CA (SPX) Feb 08, 2010
This composite image shows the effects of two galaxies caught in the act of merging. A Chandra X-ray Observatory image shows a pair of quasars in blue, located about 4.6 billion light years away, but separated on the sky by only about 70 thousand light years. These bright sources, collectively called SDSS J1254+0846, are powered by material falling onto supermassive black holes. An optical ... read more

Giant Ribbon At The Edge Of The Solar System: Mystery Solved
Huntsville AL (SPX) Jan 18, 2010
Last year, when NASA's IBEX (Interstellar Boundary Explorer) spacecraft discovered a giant ribbon at the edge of the solar system, researchers were mystified. They called it a "shocking result" and puzzled over its origin. Now the mystery may have been solved. "We believe the ribbon is a reflection," says Jacob Heerikhuisen, a NASA Heliophysics Guest Investigator from the University of Ala ... more

Do Spirals Make Us So
Paris, France (ESA) Feb 05, 2010
Using data from the NASA/ESA Hubble Space Telescope, astronomers have, for the first time, created a demographic census of galaxy types and shapes from a time before the Earth and the Sun existed, to the present day. The results show that, contrary to contemporary thought, more than half of the present-day spiral galaxies had so-called peculiar shapes only 6000 million years ago, which, if ... more

Merging Galaxies Create A Binary Quasar
Washington DC (SPX) Feb 04, 2010
Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies. Quasars are the extremely bright centers of galaxies surrounding super-massive black holes, and binary quasars are pairs of quasars bound together by gravity. Binary quasars, like other quasars, are thought to be the product of galaxy mergers. Until now, however, binary quasars ha ... more

The Stars Behind The Curtain
Paris, France (SPX) Feb 04, 2010
ESO is releasing a magnificent VLT image of the giant stellar nursery surrounding NGC 3603, in which stars are continuously being born. Embedded in this scenic nebula is one of the most luminous and most compact clusters of young, massive stars in our Milky Way, which therefore serves as an excellent "local" analogue of very active star-forming regions in other galaxies. The cluster also h ... more

    Two Tails To Tell
    Washington DC (SPX) Jan 25, 2010
    Two spectacular tails of X-ray emission have been seen trailing behind a galaxy using the Chandra X-ray Observatory. A composite mage of the galaxy cluster Abell 3627 shows X-rays from Chandra in blue, optical emission in yellow and emission from hydrogen light - known to astronomers as "H-alpha" - in red. The optical and H-alpha data were obtained with the Southern Astrophysical Research ... more

    XMM-Newton Traces Dark Matter In Faint, Distant Galaxy Groups
    Paris, France (ESA) Jan 21, 2010
    Observations of faint and distant galaxy groups made with the European Space Agency's XMM-Newton observatory have been used to probe the evolution of dark matter. The results of the study are reported in the 20 January issue of The Astrophysical Journal. Dark matter is a mysterious, invisible constituent of the Universe which only reveals itself through its gravitational influence. Underst ... more

    Hubble Catches End Of Star-Making Party
    Boston MA (SPX) Jan 18, 2010
    Galaxies throughout the universe are ablaze with star birth. But for a nearby, small spiral galaxy, the star-making party is almost over. Astronomers were surprised to find that star-formation activities in the outer regions of NGC 2976 have been virtually asleep because they shut down millions of years ago. The celebration is confined to a few die-hard partygoers huddled in the galaxy's ... more

    New Research Resolves Conflict In Theory Of How Galaxies Form
    Seattle WA (SPX) Jan 14, 2010
    For more than two decades, the cold dark matter theory has been used by cosmologists to explain how the smooth universe born in the big bang more than 13 billion years ago evolved into the filamentary, galaxy-rich cosmic web that we see today. There's been just one problem: the theory suggested most galaxies should have far more stars and dark matter at their cores than they actually do. T ... more
