Unraveling Mystery Of Gamma-Ray Bursts

Provided by Cardiff University Researchers at Cardiff University are trying to work out the possible sounds scientists might expect to hear when the ultra-sensitive LIGO and Virgo detectors are switched on in 2015. It's hoped the...

NASA's Fermi and Aqua satellites captured two different views of bursts of strength show by Hurricane Julio as it intensified. NASA's Fermi satellite saw a gamma-ray flash from Julio, while NASA's Aqua satellite saw Julio become more structurally organized as a hurricane.

A long-lasting gamma-ray burst that was first observed last year contained traits similar to those expected from explosions of some of the earliest stars in the universe, claims a new study appearing in The Astrophysical Journal.

All across the Universe high-energy charged particles are found racing in all directions. The source of these particles, collectively called cosmic rays, is masked by the interstellar magnetic field that bends their paths, making them nearly impossible to directly trace.

McDonald Observatory Sees Light From Huge Explosion 12 Billion Years Ago

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.

A Stellar Explosion On The Outer Reaches Of The Universe Provides Clues About The Formation Of Black Holes
2014-05-08 03:10:01

On 24 October 2012 observatories across the world were alerted about a huge stellar explosion, the GRB121024A, which had been located just hours before in the Eridanus constellation by NASA's Swift satellite.

An international team of astronomers has for the first time measured circular polarization in the afterglow of gamma-ray bursts, the powerful flashes of radiation originating from massive dying stars as they collapse into black holes.

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.

Our Understanding of the Universe MAXI-mized By The International Space Station

MAXI, along with other sky watching instruments, such as Swift, collect data that help researchers discover, study and understand the physics behind the powerful lifecycle of our universe.

Watch Out Buggles, Black Hole Also Killed The Radio Star
2013-12-20 14:37:23

Scientists had originally believed all gamma-ray bursts were followed by a radio afterglow, so Australian astronomers of the Centre for All-sky Astrophysics at Curtin University and the University of Sydney decided to set out to prove this theory.

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...

Hypernova -- A hypernova is a theoretical type of supernova produced when exceptionally large stars collapse at the end of their lifespan. In a hypernova, the core of the star collapses directly into a black hole and two extremely energetic jets of plasma are emitted from its rotational poles at nearly light speed. These jets emit intense gamma rays, and are a candidate explanation for gamma ray bursts. Theorists have come up with several plausible explanations for hypernovae. It may...

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
