a timely reality check |
 Colorado Springs CO (SPX) Jul 10, 2009 
The historic moment almost 40 years ago when man first set foot on the Moon had enormous impact on those who watched, often inspiring them to pursue space or science careers. This is the picture painted by the more than 100 recollections of the Apollo 11 Moon landing being published on the Space Foundation's website this week and next. The brief comments come from a wide range of ... read more 
Menlo Park CA (SPX) Jul 10, 2009The earliest stars in the universe formed not only as individuals, but sometimes also as twins, according to a paper published in Science Express. By creating robust simulations of the early universe, astrophysicists Matthew Turk and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, located at the Department of Energy's SLAC National Accelerator Laboratory, and ... more

Rochester NY (SPX) Jul 10, 2009The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick. A paper published in the July 10 issue of The Astrophysical Journal discusses the theoretical properties of "hypercompact stellar systems" and suggests that hundreds of these faint star clusters ... more  
Bethesda MD (SPX) Jul 09, 2009Launchspace has been studying the space debris issue with an eye toward private sector participation. After all, we cannot expect world governments to willingly contribute to debris reduction until they have to. No agency of a space-faring nation will want to commit huge amounts of funding to the removal of space objects. These agencies are only interested in placing satellites in orbit in ... more 
Huntsville AL (SPX) Jul 10, 2009On June 29th, neighbors of Paul Mortfield in Ontario, Canada, heard "cheers of excitement" coming from the astronomer's house. What caused the commotion? "I had just observed NASA's LCROSS spacecraft," explains Mortfield. Using no more than a backyard telescope, he caught it zipping past spiral galaxy IC3808. LCROSS is the Lunar Crater Observation and Sensing Satellite. It left Earth ... more  
Boston MA (SPX) Jul 10, 2009This beautiful image gives a new look at Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth. The curved, light blue ridge running down the center of the image shows X-ray data from the Chandra X-ray Observatory. Four of the galaxies in the group are visible in the optical image (yellow, red, white and blue) ... more |

Stanford CA (SPX) Jul 09, 2009Astronomers now have a better understanding of how stars progress, thanks to NASA's Fermi Space Telescope that has detected numerous pulsars by the gamma rays they emit. When a massive star explodes, it leaves behind a compact core called a pulsar. Like a spinning firecracker spitting out sparks, these magnetized cores emit high-energy light particles called gamma rays as they rapidly ... more  
Tempe AZ (SPX) Jul 07, 2009Two astronomers at The University of Arizona will screen their 45-minute documentary this week on the impact of the Hubble Space Telescope and NASA on the careers of one specific group of astronomers. The film, "Hubble's Diverse Universe," will show this Friday, July 10, at 7 p.m. at the Museum of African-American Technology and Science Village in Oakland, Calif. It will air there a second ... more 
Los Angeles CA (SPX) Jul 06, 2009At the start of the Obama administration, our young and energetic president made clear that NASA must shed its ennui and business as usual attitude and get back to executing some bold and daring projects. He appointed a transition team to look into changes. At that time, I recall there was talk of bringing various seemingly disparate agencies and departments together, especially the ... more 
Canberra, Australia (SPX) Jul 07, 2009CSIRO astronomers have revealed the hidden face of an enormous galaxy called Centaurus A, which emits a radio glow covering an area 200 times bigger than the full Moon. The galaxy's radio waves have been painstakingly transformed into a highly detailed image, which is being unveiled to the public for the first time. Centaurus A lies 14 million light-years away, in the southern ... more |
