McDonald Observatory Sees Light From Huge Explosion 12 Billion Years Ago
2014-06-05 03:04:01

Margaret Allen, Southern Methodist University 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. Known as a gamma-ray burst, light from the rare, high-energy explosion traveled for 12.1 billion years before it was detected and observed by a telescope, ROTSE-IIIb, owned by Southern Methodist University, Dallas. Gamma-ray bursts are believed to be the catastrophic...

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Spitzer Space Telescope has used its dust-piercing infrared vision to help in analyzing a recently-discovered supernova in galaxy M82. It joined with several other instruments to create a detailed portrait of the stellar explosion, officials from the US space agency announced on Wednesday. The new supernova, SN 2014J, is the closest of its kind to be observed in the past few decades and has launched a global observing...

[ Watch the Video: What Interstellar Blast Is Lighting Up The Sky? ] redOrbit Staff & Wire Reports - Your Universe Online 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. The stellar explosion, which has been designated SN 2014J, lies approximately 12 million light-years away...

New Insights Into Cosmic Phenomena Provided By Swift Satellite
2013-12-17 05:07:02

redOrbit Staff & Wire Reports - Your Universe Online 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. The research team studied eight years’ worth of observations collected during the Swift Gamma-Ray Burst Mission to compile a catalog of major celestial X-ray sources – a list that includes more than 150,000 high-energy...

Looking At Magnetic Fields Of Gamma-ray Bursts
2013-12-04 16:25:22

NASA 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. Gamma-ray bursts are the most luminous explosions in the cosmos. Most are thought to be triggered when the core of a massive star runs out of nuclear fuel, collapses...

Heavy Metals In The Infant Universe

April Flowers for redOrbit.com - Your Universe Online 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. This flash of light traveled across space for 12.7 billion years to a planet that hadn't even existed at the time of the explosion - our Earth. Astronomers have analyzed this light to learn about a galaxy...

Shockingly Bright Gamma-Ray Burst Observed By Fermi, Swift
2013-05-06 04:44:26

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online 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. Fermi´s main instrument the Large Area Telescope (LAT) detected gamma-rays as high as 94 giga-electron volts (GeV),...

NASA's Swift Team Collects More Than 100 Snapshots For Image Gallery Gift

NASA 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. Although small by the standards of ground-based observatories, Swift's Ultraviolet/Optical Telescope (UVOT) plays a critical role in rapidly pinpointing the locations of gamma-ray bursts (GRBs), the brightest explosions in the cosmos. But as the proxy to the human eye aboard Swift, the UVOT takes some amazing pictures. The Swift team is...
