Titan's Smoggy Sand Grains Pasadena CA (SPX) May 05, 2008 
Titan and Earth have much in common, but not when it comes to sand. On Earth, sand grains form by breaking things down, but on Titan, the opposite may be true - with much of the sand a product of building things up. That's one theory Cassini scientists are considering after studying Titan's massive sand dunes with the visible and infrared mapping spectrometer on the Cassini Saturn orbiter.

The eta Aquarid Meteor Shower
Washington DC (SPX) May 05, 2008The eta Aquarid meteor shower peaks this year on Tuesday, May 6th. The best time to look, no matter where you live, is during the hours immediately before sunrise. If you can, get away from city lights; you will see more meteors from the dark countryside. 2008 should be a good year for the eta Aquarid meteors. The Moon is new, which means no lunar glare, and Earth is expected to pass ... more Temporary cooling trend may offset warming 
New York (UPI) May 2, 2008 German scientists said temporary climate variations may temporarily offset the long-term global warming trend. Researchers from the Leibniz Institute of Marine Sciences and the Max Planck Institute for Meteorology said computer simulations and measurements of ocean temperatures suggest that global warming will weaken slightly during the the next decade. The findings are published ... more NASA Calls On APL To Send A Probe To The Sun 
Baltimore MD (SPX) May 05, 2008The Johns Hopkins University Applied Physics Laboratory is sending a spacecraft closer to the sun than any probe has ever gone - and what it finds could revolutionize what we know about our star and the solar wind that influences everything in our solar system. NASA has tapped APL to develop the ambitious Solar Probe mission, which will study the streams of charged particles the sun hurls ... more Canadian satellite to detect Earth hits 
Ottawa (UPI) May 2, 2008 Canadian researchers are working on a tiny satellite that will alert the world to the potential of asteroid strikes. "This is the first space-based asteroid-searching telescope," said Alan Hildebrand of the University of Calgary (Alberta), one of two principal scientists for the satellite. He told the Canwest News Service the Near Earth Object Surveillance Satellite, set to be ... more Oldest Known Objects Are Surprisingly Immature 
Boston MA (SPX) Apr 30, 2008Some 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. Globular clusters, dense bunches of up to millions of stars found in all galaxies, are among the oldest known objects in ... more |

Washington (AFP) May 1, 2008The space shuttle's pending upcoming mission to continue maintenance and repair work on the Hubble telescope, which had been set for August 28, will be pushed back four to five weeks, NASA said Thursday. "Right now Hubble's mission is scheduled for August 28; we really cannot make that date with the external tank processing," shuttle program manager John Shannon explained at a press confere ... more Scientists Find Rings Of Jupiter Are Shaped In Shadow 
College Park MD (SPX) May 02, 2008Scientists from the University of Maryland and the Max-Planck Institute for Solar System Research in Germany appear to have solved a long-standing mystery about the cause of anomalies in Jupiter's gossamer rings. They report that a faint extension of the outermost ring beyond the orbit of Jupiter's moon Thebe, and other observed deviations from an accepted model of ring formation, result from th ... more High-Flying Electrons May Provide New Test Of Quantum Theory 
Washington DC (SPX) May 02, 2008Researchers at the National Institute of Standards and Technology and Max Planck Institute for Physics in Germany believe they can achieve a significant increase in the accuracy of one of the fundamental constants of nature by boosting an electron to an orbit as far as possible from the atomic nucleus that binds it. The experiment would not only mean more accurate identifications of ... more Galaxy Evolution Explorer Celebrates Five Years In Space 
Pasadena CA (SPX) Apr 30, 2008Since 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. The galaxy's extended arms are the blue filaments that curve around its edge, creating its outer disk. Tints of blue in M106 ... more |

Baltimore MD (SPX) Apr 30, 2008Imagine 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 ... more Austria Declares Intent To Join ESO 
Vienna, Austria (SPX) Apr 28, 2008At a press conference today at the University of Vienna's Observatory, the Austrian Science Minister Johannes Hahn announced the decision by the Austrian Government to seek membership of ESO from 1 July this year. Said Minister Hahn: "With membership of ESO, Austria's scientists will receive direct access to the world's leading infrastructure in astronomy. This strengthens Austria as a ... more Shanghai's Own Moon Vehicle Passes Test 
Beijing, China (XNA) Apr 28, 2008Shanghai has developed a lunar rover that it hopes to be chosen for China's first moon landing in 2013, the city government announced yesterday. The Shanghai Science and Technology Commission said the key technology of the rover has passed a technical appraisal by the government. The technology mainly covers the rover's maneuverability and detection sensors. The rover, which hasn't been gi ... more The Physics Of Whipped Cream 
Washington DC (SPX) Apr 28, 2008Let's do a little science experiment. If you have a can of whipped cream in the fridge, go get it out. Spray a generous dollop into a spoon and watch carefully. Notice anything interesting? The whipped cream just did something rather puzzling. First it flowed smoothly out of the nozzle like a liquid would, and then, a moment later, it perched rigidly in the spoon as if it were solid. What made ... more
