News About Stellar Chemistry 20-NOV-09 en-us Rochester NY (SPX) Nov 20, 2009 - A multi-trillion-watt laser at the University of Rochester has simulated a stellar jet-an outpouring of matter from a fledgling star-with unprecedented realism.]]> Paris, France (ESA) Nov 20, 2009 - The evolution of bulges in the centres of spiral galaxies puzzles astronomers. A recent NASA/ESA Hubble Space Telescope image of NGC 4710 is part of a survey that has been conducted to learn more about the formation of bulges, which are a substantial component of most spiral galaxies.]]> Paris, France (SPX) Nov 19, 2009 - Using ESO's Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a "vampire star", which in November 2000 underwent an outburst after gulping down part of its companion's matter.]]> Cambridge MA (SPX) Nov 19, 2009 - The constellation of Orion is a hotbed of massive star formation, most prominently in the Great Nebula that sits in Orion's sword. The glowing gas of the Nebula is powered by a group of young massive stars, but behind it is a cluster of younger stars and clumps of gas. Still gathering together under gravity's pull, these gas clumps will eventually ignite into stars.]]> Durham, UK (SPX) Nov 12, 2009 - The Universe's infant galaxies enjoyed rapid growth spurts forming stars like our sun at a rate of up to 50 stars a year, according to scientists at Durham University.]]> Paris, France (SPX) Nov 09, 2009 - This week, Astronomy and Astrophysics publishes a somewhat unusual research article because it is co-authored by German high-school students. Led by astronomer Klaus Beuermann (University of Goettingen, Germany), the team involves a secondary school physics teacher, three students from two high schools in Goettingen, and three professional astronomers.]]> Berkeley CA (SPX) Nov 09, 2009 - An unusual supernova rediscovered in seven-year-old data may be the first example of a new type of exploding star, possibly from a binary star system where helium flows from one white dwarf onto another and detonates in a thermonuclear explosion.]]> Boston MA (SPX) Nov 05, 2009 - Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object.]]> Edmonton, Canada (SPX) Nov 05, 2009 - University of Alberta physics professor Craig Heinke has solved a mystery that lies 11,000 light years beyond Earth. A supernova (or exploding star), 20 times heavier than our sun blasted apart, leaving behind a small core that has puzzled astronomers since its discovery in 1999.]]> Stanford, Calif. (UPI) Nov 4, 2009 - U.S. and Welsh researchers say they've obtained a detailed picture of the early universe using a telescope in the Antarctic.]]>
