| Posted: 06 Mar 2013 10:40 AM PST After nearly a decade of careful observations astronomers have measured the distance to our neighboring galaxy, the Large Magellanic Cloud, more accurately than ever before. This new measurement also improves our knowledge of the rate of expansion of the Universe — the Hubble Constant — and is a crucial step towards understanding the nature of the mysterious dark energy that is causing the expansion to accelerate.  |
| Probing extreme matter through observations of neutron stars Posted: 06 Mar 2013 10:38 AM PST Neutron stars, the ultra-dense cores left behind after massive stars collapse, contain the densest matter known in the Universe outside of a black hole. New results have provided one of the most reliable determinations yet of the relation between the radius of a neutron star and its mass. These results constrain how nuclear matter – protons and neutrons, and their constituent quarks – interact under the extreme conditions found in neutron stars.  |
| Herschel space observatory to complete its mission soon Posted: 06 Mar 2013 10:17 AM PST The Herschel space observatory is expected to exhaust its supply of liquid helium coolant in the coming weeks, after spending more than three years studying the cool universe and surpassing the expectations of the international team of scientists involved.  |
| Comet to make close flyby of Red Planet in October 2014 Posted: 06 Mar 2013 10:14 AM PST Comet 2013 A1 (Siding Spring) will make a very close approach to Mars in October 2014.  |
| Robotic fish gain new sense: Navigate water currents and turbulence Posted: 06 Mar 2013 05:42 AM PST Scientists have developed robots with a new sense -- lateral line sensing. All fish have this sensing organ but so far it had no technological counterpart on human-made underwater vehicles.  |
| Curtains down for the black hole firewall paradox: Making gravity safe for Einstein again Posted: 06 Mar 2013 05:41 AM PST Scientists have revealed new insights into the life and death of black holes. Their findings dispel the so-called firewall paradox which shocked the physics community when it was announced in 2012 since its predictions about large black holes contradicted Einstein's crowning achievement -- the theory of general relativity. Those results suggested that anyone falling into a black hole would be burned up as they crossed its edge -- the so-called event horizon.  |
| Chemists develop efficient material for carbon capture Posted: 05 Mar 2013 07:09 AM PST Chemists have discovered a more efficient, less expensive and reusable material for carbon dioxide capture and separation.  |
| Black hole collision may have sparked celestial fireworks in the Milky Way several million years ago Posted: 01 Mar 2013 12:32 PM PST There is growing evidence that several million years ago the center of the Milky Way galaxy was site of all manner of celestial fireworks and a pair of astronomers propose that a single event -- a black hole collision -- can explain all the "forensic" clues.  |
