Latest Discoveries at Penn State


The Penn Stater reports for the latter half of 2010 that the Swift satellite has made some astonishing results from gamma-ray burts.
After five remarkable years of discovery, the Swift satellite has rewritten the book on gamma-ray bursts.

Gamma-ray bursts have been observed since 1967.  Swift consists of three telescopes in tandem: Burst Alert, X-ray, and Ultraviolet Optical..
Short bursts result from collisions between neutron stars and are a trillion times brighter than the sun.  In spring 2009, a ten-second gamma-ray burst had an afterglow in X-ray light.  Yet only infared telescopes  on the ground could pick up the glow.  It proved to be just over thirteen billion years ago.  GRB090423
