Sentences with phrase «bursts of gamma ray radiation»

For this theory to work, the beams released by black holes would have to have strong, self - generated magnetic fields and the rotation of particles around the fields would then give off powerful bursts of gamma ray radiation.

Not exact matches

The flashes are known as gamma - ray bursts because most of their energy is in the form of high - energy radiation, including gamma rays and X-rays.

A Chandra x-ray spectrum (inset) suggests that radiation from a gamma ray burst lit up part of a shell from a previously exploded supernova.

A gamma ray burst is thought to emerge when jets of hot matter moving at near — light - speed shoot out along the rotational axis of the newborn black hole, beaming radiation into space like a lighthouse.

Gamma - ray bursts are mysterious flashes of intense high - energy radiation that appear from random directions in space.

Since the early 1970s, scientists had debated the nature of gamma - ray bursts, enigmatic flashes of energetic radiation that pop off hundreds of times a year.

It sent a flood of high - energy radiation towards Earth that lasted much longer than is typical for a gamma - ray burst (GRB).

The intense radiation was part of a gamma - ray burst that lasted a minute and which marked the death of a massive star transmogrifying itself into a black hole.

Neutron star mergers like this produce gamma ray bursts — beams of radiation that can destroy planets or make them inhospitable to life.

In rare cases, black hole births are even more spectacular, with the star firing out powerful jets of high - energy radiation as it dies — a phenomenon known as a gamma - ray burst.

These highly energetic bursts of hard radiation have been seen by gamma - ray satellites such as Fermi and Swift, but the exact origin of these quickly disappearing flashes of gamma - rays remains unknown.

However, rather than emitting violent bursts of gamma - ray radiation, like blazars, Seyfert galaxies are known for their strong ultra-violet emissions.

In this artist's rendering, jets of high - energy radiation shoot out from a Gamma - ray burst, signaling the death of a massive star.

Here's the deal with gamma - ray bursts: When a huge star collapses, it produces a boatload of radiation in concentrated streams.
