Latest Swift Gamma-Ray Burst Mission Stories
GREENBELT, Md., Jan. 6 /PRNewswire-USNewswire/ -- Astronomers combining data from NASA's Swift satellite, the W. M. Keck Observatory in Hawaii, and other facilities have, for the first time, identified gas molecules in the host galaxy of a gamma-ray burst.
An explosion originating near the edge of the universe has been seen by an orbiting NASA telescope. The burst of gamma rays is the farthest such event ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away.
NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away.
Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen. The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth.
Data from satellites and observatories around the globe show a jet from a powerful stellar explosion witnessed March 19 was aimed almost directly at Earth.
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought.
Thanks to a fortunate observation with NASA's Swift satellite, astronomers, for the first time, have caught a normal supernova at the moment of its birth--the first instant when an exploding star begins spewing its energy into space, transforming into a supernova that during its brief lifetime will shine brighter than billions of stars combined.
A powerful stellar explosion detected March 19 by NASA's Swift satellite has shattered the record for the most distant object that could be seen with the naked eye. The explosion was a gamma ray burst.
Gamma-ray bursts are short-lived events, lasting between a few milliseconds to a few minutes. The brightest of them emit more energy in a few seconds than our Sun will emit in its whole 10 billion year lifetime.
Using the powerful one-two combo of NASAâ€™s Swift satellite and the Gemini Observatory, astronomers from a number of institutions, including Johns Hopkins, have detected a mysterious type of cosmic explosion farther back in time than ever before.
