Giant Ultraviolet Rings Found In Resurrected GalaxiesPasadena CA (JPL) Aug 12, 2010 Astronomers have found mysterious, giant loops of ultraviolet light in aged, massive galaxies, which seem to have a second lease on life. Somehow these "over-the-hill galaxies" have been infused with fresh gas to form new stars that power these truly gargantuan rings, some of which could encircle several Milky Way galaxies. The discovery of these rings implies that bloated galaxies presumed "dead" and devoid of star-making can be reignited with star birth, and that galaxy evolution does not procee ... read more |

Professor Liane Benning (University of Leeds) and Dr. Dominique Tobler (University of Glasgow) are travelling to Ny-Alesund on the island of Svalbard to investigate how the snow and ice there was first colonized by extremophiles - organis ... more  
Pasadena CA (JPL) Aug 09, 2010There are several major meteor showers to enjoy every year at various times, with some more active than others. For example, April's Lyrids are expected to produce about 15 meteors an hour at their peak for observers viewing in good conditions. Now, if you put the same observer in the same good conditions during a higher-rate shower like August's Perseids or December's Geminids, that perso ... more  
Washington DC (SPX) Aug 06, 2010A beautiful new image of two colliding galaxies has been released by NASA's Great Observatories. The Antennae galaxies, located about 62 million light years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold), and the Spitzer Space Telescope (red). The collision, which began more than 100 million years ago and is still ... more |

Planets Align For The Perseid Meteor ShowerHuntsville AL (SPX) Aug 06, 2010 You know it's a good night when a beautiful alignment of planets is the second best thing that's going to happen. Thursday, August 12th, is such a night. The show begins at sundown when Venus, Saturn, Mars and the crescent Moon pop out of the western twilight in tight conjunction. All four heavenly objects will fit within a circle about 10 degrees in diameter, beaming together through the dusky colors of sunset. No telescope is required to enjoy this naked-eye event. The planets will hang to ... read more |
