A brief but extremely powerful cosmic blast from a distance galaxy has taken the record for the brightest light ever seen from Earth.

It was emitted by a gamma ray burst seven billion light-years away and created more energy in a few seconds than the sun will burn in its 10 billion year lifetime.

Discovery - Researchers - Curtin - University - Western

The discovery, led by researchers from Curtin University in Western Australia involved more than 300 scientists from around the world.

Gamma-ray bursts are the most energetic events in the universe - the most massive since the Big Bang, says co author of the study, Dr Gemma Anderson.

Beams - Earth - Milliseconds - Hours

They happen so far away they can only be detected when the beams are pointed directly at Earth and can last from a few milliseconds to a few hours.

'They are likely produced by a massive star being blown apart in a supernova, with the resulting explosion leaving behind a black hole', said Dr Anderson.

Gamma - Ray - Bursts - Sky - Warning

Gamma ray bursts appear in the sky without warning, about once per day.

This 'massive burst' reached the Earth on the 14th of January 2019 and was detected by two space satellites - the Neil Gehrels Swift Observatory built by University College London and the Fermi Gamma-ray Space Telescope.

Burst - GRB - Seconds - Coordinates - Astronomers

The burst was named GRB 190114C and, within 22 seconds, its coordinates were sent to astronomers across the globe.

Astronomers at the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescopes in the Canary Islands were the first to survey the bursts.

In the first seconds after they started observing, the two MAGIC telescopes detected particles...
