New Gamma-Ray Burst Smashes Cosmic Distance Record
London, UK (SPX) May 01, 2009NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen. "Swift was designed to catch these very distant bursts," said Swift lead scientist Neil Gehrels at NASA ... read more *New* Comments: 0 Herschel Cryostat Filled With Liquid Helium In Preparation For May Launch 
Paris, France (ESA) May 01, 2009One of the last activities to take place in S5B is the filling of the Herschel cryostat with liquid helium and its conversion into superfluid helium-II. The primary objective of achieving a full cryostat, above 95%, with a helium temperature below 1.7 Kelvin was reached on Friday 25 April and the activities now focus on maintaining the good helium conditions until the spacecraft can be mov ... read more *New* Comments: 0 Pillars Of Creation Formed In The Shadows 
Hertfordshire, UK (SPX) Apr 27, 2009Research by astronomers at the Dublin Institute of Advanced Studies suggests that shadows hold the key to how giant star-forming structures like the famous "Pillars of Creation" take shape. The pillars are dense columns within giant clouds of dust and gas where massive stars form. Several theories have been proposed to explain why the pillars develop around the edge of ionized gas bubbles ... read more *New* Comments: 0 Dust Cleared To Get Better Look At Youngest Supernova Remnant 
Raleigh NC (SPX) Apr 24, 2009Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. Their new data provides evidence that this remnant is from a type Ia supernova - the explosion of a white dwarf star - and raises questions about the ways in which magnetic ... read more *New* Comments: 0 Gamma-ray burst sets distance record 
Washington, April 28, 2009 The U.S. space agency says its Swift satellite has found a gamma-ray burst from a star that died when the universe was only 630 million years old. The National Aeronautics and Space Administration said the event occurred when the universe was less than 5 percent of its present age and is the most distant cosmic explosion ever seen. "Swift was designed to catch these very distant ... read more *New* Comments: 0 |
