Latest Gamma-ray burst Stories
In Star Wars, the Death Star is a massive spaceship capable of destroying a planet with just one shot of its laser, but a recently-discovered white dwarf star may have ripped apart a planet at its core by coming too close to it, making it a real-life Death Star.
Astronomers found that the type of supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before, and this questions how fast the universe has been expanding.
This bad boy has a sweet name and is ready to roll and kick some gamma-ray booty.
Inaugural ceremony March 19-20 marks completion of powerful system to detect gamma rays and cosmic rays (PRWEB) March 20, 2015 Supernovae, neutron star
A dwarf galaxy recently discovered orbiting the Milky Way appears to be radiating gamma rays, and leading researchers from Brown and Carnegie Mellon universities hypothesize that it could be filled with particles of the mysterious substance known as dark matter.
Astronomers have detected unusual quick, bright flashes of radio waves that originate from unknown sources in space for the first time ever, according to research published in Monthly Notices of the Royal Astronomical Society.
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'.
New analysis of high energy blasts from a magnetar has resulted in the discovery of underlying signals related to seismic waves rippling throughout the highly magnetized neutron star.
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.
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,...
