![]() Pasadena CA (JPL) Jan 12, 2010 For the first time, two astronomers have explained the diversity of galaxy shapes seen in the universe. The scientists, Dr. Andrew Benson of the California Institute of Technology (Caltech) and Dr. Nick Devereux of Embry-Riddle University in Arizona, tracked the evolution of galaxies over thirteen billion years from the early Universe to the present day. Their results appear in the journal Month ... read more |

Planning Our Phases On The Moon![]() Space agencies around the world have been gearing up for the return of human explorers to the Moon by developing fantastic new technologies. From rovers to rockets, these technologies are necessary for transporting astronauts to the Moon and for performing surface geology and biology experiments. As the prospect of a renewed human presence on the Moon approaches, it may be time to think ... more SMU Hosts NOvA Scientists ![]() Physicists may see data as soon as late summer from the prototype for a $278 million science experiment in northern Minnesota that is being designed to find clues to some fundamental mysteries of the universe, including dark matter. But it could take years before the nation's largest "neutrino" detector answers the profound questions that matter to scientists. Construction is underwa ... more How To Stir Galaxy Disks ![]() Two CNRS researchers at the Strasbourg Observatory have shown that in spiral galaxies containing a central bar - an elongated structure composed of stars - a vigorous mixing of stars in the disk takes place. They presented their work this week at the meeting of the American Astronomical Society. Until now, astronomers have attributed this mixing process, named "radial migration," solely ... more |

Astronomy Question Of The Week: How Old Is The Universe![]() In the field of archaeology the age of finds or the time of events can sometimes be determined relatively easily, for example via the number of tree rings or the rate of decomposition of radioactive elements. However, there is unfortunately no direct and absolute indicator for the age of the Universe. Astronomers have, however, found two ways to arrive at a good estimate. The Univers ... more Rohrabacher Suggests Partnership With Russia On Asteroid Interception Project ![]() Rep. Dana Rohrabacher (R-CA) has sent a letter to Anatoly Perminov, head of the Russian Space Agency, praising Russia's decision to set up a mission to alter the path of an asteroid on a potential collision course with Earth. The impetus for such a project stems from the current trajectory of Asteroid Apophis, scheduled to makes its first pass around Earth in the year 2029, close enough to ... more Astronomers Simulate How White-Dwarf Stars Merge And Go Supernova ![]() Supernovae are spectacular events: Suddenly somewhere in the heavens a "new star" lights up and shines as bright as a whole galaxy consisting of billions of stars. The mechanisms behind these cosmic catastrophes are varied. Researchers at the Max-Planck-Institute for Astrophysics in Garching have now used computer simulations to confirm that some of these bright supernovae are due to the merger ... more |
