Latest Swift Gamma-Ray Burst Mission Stories
Intense light from the enormous explosion of a star more than 12 billion years ago — shortly after the Big Bang — recently reached Earth and was visible in the sky.
NASA’s Spitzer Space Telescope has used its dust-piercing infrared vision to help in analyzing a recently-discovered supernova in galaxy M82.
Several NASA spacecraft and Earth-based observatories, including the Hubble Space Telescope and the Chandra X-ray Observatory, are studying an incredibly close supernova that took place on January 21, officials from the US space agency announced on Friday.
By analyzing data collected by NASA’s Swift robotic spacecraft, astronomers from the University of Leicester have reportedly discovered the location of nearly 100,000 previously unknown cosmic X-ray sources.
A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team of astronomers from Britain, Slovenia and Italy has glimpsed the infrastructure of a burst's high-speed jet.
A star exploded more than 12 billion years ago, ripping itself apart and blasting debris outward in twin jets at nearly the speed of light. The star shone so brightly at its death that it outshone its entire galaxy by a million times.
On Saturday, April 27, the Fermi Gamma-ray Telescope detected a sudden, powerful flux of high-energy gamma-rays, indicating a historic burst event in a distant galaxy. The instrument then notified other telescopes located in space and on the ground that a Gamma-ray Burst (GRB) had been detected.
Of the three telescopes carried by NASA's Swift satellite, only one captures cosmic light at energies similar to those seen by the human eye.
