Although previous supernovas have been seen this early, the new observation is the earliest one with a spectrum — an accounting of the emitted light broken up by wavelength — taken six hours after the explosion, Yaron and colleagues report online February 13 in Nature Physics.

In the case of Tycho's supernova remnant, astronomers have discovered that a reverse shock wave racing inward at Mach 1000 (1000 times the speed of sound) is heating the remnant and causing it to emit X-ray light.

For a brief burst of time, supernovae can radiate more energy than the sun will emit in its lifetime.

At his proposed distance, the 1181 explosion was roughly a fifth as luminous as the 1987 supernova in the Large Magellanic Cloud, a nearby galaxy, that also emitted less light than the norm.

The top candidates, the astronomers suggested, are a neutron star, possibly a highly - magnetic magnetar, surrounded by either material ejected by a supernova explosion or material ejected by a resulting pulsar, or an active nucleus in the galaxy, with radio emission coming from jets of material emitted from the region surrounding a supermassive black hole.

They devour whatever gases survive the supernova blowout, and in the process emit high - speed plasma jets that blast away remaining gases.

In the last years he has focused in the emerging area of Gravitational Wave Astronomy, which consists in the detection and analysis of gravitational radiation emitted by cosmic sources (core collapse supernovae, compact binary coalescence, etc.In the last years he has focused in the emerging area of Gravitational Wave Astronomy, which consists in the detection and analysis of gravitational radiation emitted by cosmic sources (core collapse supernovae, compact binary coalescence, etc.in the emerging area of Gravitational Wave Astronomy, which consists in the detection and analysis of gravitational radiation emitted by cosmic sources (core collapse supernovae, compact binary coalescence, etc.in the detection and analysis of gravitational radiation emitted by cosmic sources (core collapse supernovae, compact binary coalescence, etc.).

At the moment of their explosion, supernovae emit a good fraction of their energy in a burst of X-rays.

Astronomers now believe, however, that GRBs seems so powerful because most of their energy is being beamed out of bi-polar jets in a brief burst, unlike the later stage of a supernova when neutrinos are emitted from all around the exploding star.

Indeed, GRBs appear to emit produce even more energy than supernovae or even quasars (which are energetically bright accretion disks and bi-polar jets around supermassive black holes that are most commonly found in the active nuclei of some distant galaxies and possibly even in the pre-galaxy period after the Big Bang).

The Sun doesn't emit gamma ray - few no stars are hot enough: http://space.about.com/od/astronomydictionary/g/Gamma-Rays.htm You get gamma in space from supernovas and blackholes.

These animations illustrate the physical process which the theory about the cosmic connection to Earth's climate proposes: 1) A giant star explodes in a supernova explosion and emits cosmic rays, 2) cosmic rays enter Earth's atmosphere, 3) rays release free electrons which act a catalysts for the building blocks for cloud condensation nuclei, 4) on which water vapour condenses into clouds.
