News About Stellar Chemistry 16-MAY-08 en-us London UK (SPX) May 14, 2008 - An international team of astronomers have found the youngest known supernova remnant in the Galaxy. Using observations made with the Very Large Array (VLA) radio telescope in the US and the orbiting Chandra X-ray observatory, the scientists report that the remnant, G1.9+0.3, is just 150 years old.]]> ]]> Washington DC (SPX) May 16, 2008 - Astronomers have discovered a speedy spinning pulsar in an elongated orbit around an apparent Sun-like star, a combination never seen before, and one that has them puzzled about how the strange system developed.]]> Paris, France (ESO) May 14, 2008 - Astronomers have made use of ESO's Very Large Telescope to detect for the first time in the ultraviolet the carbon monoxide molecule in a galaxy located almost 11 billion light-years away, a feat that had remained elusive for 25 years. This detection allows them to obtain the most precise measurement of the cosmic temperature at such a remote epoch.]]> Paris, France (ESA) May 12, 2008 - New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this proto-typical pair of interacting galaxies is in fact much closer to us than previously thought - at 45 million light-years instead of 65 million light-years.]]> ]]> Chicago IL (SPX) May 05, 2008 - Robert Fisher and Cal Jordan are among a team of scientists who will expend 22 million computational hours during the next year on one of the world's most powerful supercomputers, simulating an event that takes less than five seconds. Fisher and Jordan require such resources in their field of extreme science.]]> Boston MA (SPX) Apr 30, 2008 - Some of the oldest objects in the Universe may still have a long way to go, according to a new study using NASA's Chandra X-ray Observatory. These new results indicate that globular clusters might be surprisingly less mature in their development than previously thought.]]> Greenbelt MD (SPX) May 02, 2008 - Using observations from NASA's Rossi X-ray Timing Explorer (RXTE), an international team of astronomers has discovered a timing mechanism that allows them to predict exactly when a superdense star will unleash incredibly powerful explosions. "We found a clock that ticks slower and slower, and when it slows down too much, boom! The bomb explodes," says lead author Diego Altamirano of the University of Amsterdam in the Netherlands.]]> ]]> Austin TX (SPX) May 02, 2008 - University of Texas at Austin astronomers Michael H. Montgomery and Kurtis A. Williams, along with graduate student Steven DeGennaro, have predicted and confirmed the existence of a new type of variable star with the help of the 2.1-meter Otto Struve Telescope at McDonald Observatory. The discovery will be announced in today's issue of Astrophysical Journal Letters.]]> Pasadena CA (SPX) Apr 30, 2008 - Since its launch five years ago, the Galaxy Evolution Explorer has photographed hundreds of millions of galaxies in ultraviolet light. M106 is one of those galaxies, and from 22 light years away, it strikes a pose in blue and gold for this new commemorative portrait.]]> Baltimore MD (SPX) Apr 30, 2008 - Imagine receiving an announcement touting the birth of a baby 20 inches long and weighing 180 pounds. After reading this puzzling message, you would immediately think the baby's weight was a misprint. Astronomers looking at galaxies in the universe's distant past received a similar perplexing announcement when they found nine young, compact galaxies, each weighing in at 200 billion times the mass of the Sun.]]> ]]> ]]> Washington DC (SPX) Apr 25, 2008 - Fifty nine new images of colliding galaxies make up the largest collection of Hubble images ever released together. As this astonishing Hubble atlas of interacting galaxies illustrates, galaxy collisions produce a remarkable variety of intricate structures.]]> Ann Arbor MI (SPX) Apr 25, 2008 - For the first time, astronomers have observed a blazar in action, substantiating a prevailing theory about how these luminous and energetic galactic cores work. A paper on the observations is published in the April 24 issue of Nature. Two University of Michigan astronomers contributed to the research, which was led by Alan Marscher of the Institute for Astrophysical Research at Boston University.]]> Pasadena CA (SPX) Apr 18, 2008 - A new image from NASA's Galaxy Evolution Explorer shows baby stars sprouting in the backwoods of a galaxy -- a relatively desolate region of space more than 100,000 light-years from the galaxy's bustling center. The striking image, a composite of ultraviolet data from the Galaxy Evolution Explorer and radio data from the National Science Foundation's Very Large Array in New Mexico, shows the Southern Pinwheel galaxy, also known simply as M83.]]> Advertise in this newsletter or website click for advertising kit - PDF File
