Supernova Recreation Reveals How Interstellar Magnetic Fields May Have Formed

Brett Smith for redOrbit.com - Your Universe Online Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small-scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space, according to a new report in the journal Nature Physics. "Magnetic fields are ubiquitous in the universe," said study author Don Lamb, a professor in astronomy and astrophysics at the University...

How HIV is assembled and released from infected cells Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. Much has been learned about HIV-1, the virus that causes the disease. However, basic aspects of person-to-person transmission and of the progressive intercellular infection that depletes the immune system of its vital T cells remain imperfectly understood. In a paper...

An international team of scientists using three NASA satellites and a host of ground-based telescopes believes it has solved the greatest remaining mystery of the mysterious gamma-ray bursts (GRBs), the most powerful explosions in the universe. The shorter of two versions of these bursts appear to be caused by the collision of closely orbiting neutron stars or one of those compact stars and a black hole, said Don Lamb, the Louis Block Professor in Astronomy & Astrophysics at the...

NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago. Now a faculty member at the University of North Carolina, Chapel Hill, Reichart led the team that discovered the afterglow of the explosion, called a gamma-ray burst (GRB), which culminated in the confirmation of his and Lamb's earlier...

Observations of a cosmic explosion detected on Feb. 15 by two NASA satellites have thrown into doubt one popular explanation for such explosions and have also seriously weakened the argument for yet another, according to University of Chicago astrophysicist Don Lamb. But solving the mystery any time soon may be forestalled by plans to shut down one of the satellites in September. The explosion in question is a powerful burst of X-rays called an X-ray flash that was observed by NASA's Swift...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
