New observations of dust around young stars suggest collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn&#39;t likely stop the formation

An embryonic star, just beginning its life as the center of a planetary system, is apparently deluged with massive rainfall as icy material vaporizes and refreezes. Astronomers are observing one such star in a nebula about 1,000 light years from Earth with the Spitzer Space Telescope.

In a series of landmark observations gathered over a period of four months, NASA's Swift satellite has challenged some of astronomers' fundamental ideas about gamma-ray bursts (GRBs), which are among the most extreme events in our universe.

Imagine two stars with winds so intense that they eject an Earthâs worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce multimillion-degree gas, which radiates brilliantly in X-rays.

A new report released by an American Physical Society (APS) Special Committee on NASA Funding for Astrophysics has questioned the space agency's Moon, Mars and Beyond initiative. The APS assessment warns that t  he cost of overcoming technological challenges to make real the plan could far exceed budgetary projections and that numerous&nbsp;approved science programs could be jeopardized.

Duke University -- A Supernova Early Warning System (SNEWS) that detects ghostlike neutrino particles that are the earliest emanations from the immense, explosive death throes of large stars will alert astronomers of the blasts before they can see the flash.     SNEWS "could allow astronomers a chance to make unprecedented observations of the very early turn-on of the supernova," wrote the authors of an article about the new system in the September issue of the "New Journal of Physics."     They also noted that "no supernova has ever been observed soon after its birth."     Big stars end their lives in explosive gravitational collapses so complete that even the brilliant flashes of light usually announcing these extremely rare "supernova" events stay trapped inside, unseen by astronomers, for the first hours or days...

THE word accident has been the main casualty at Waitara's Methanex plant for the last seven years.  "We have outlawed the word," says director of corporate resources Jayne Francis. "It has connotations of an act of God, of something that cannot be avoided.
