Scientists Receive Stunningly Bright Radio Blast From Deep In The Universe

  |   Tech News

Scientists have found a stunningly bright radio emission coming from deep in the universe. The quasar is the brightest radio signal ever received from the early universe, and could allow us to understand the beginnings of the cosmos's first galaxies. Quasars are made up of huge black holes that are swallowing matter at the centre of galaxies. As that happens, a vast amount of radiation is emitted from what are the brightest objects in the universe – that then bursts out across the universe.

It was that radiation that reached Earth as a radio signal, allowing astronomers to see an early quasar in unprecedented detail. It comes from a time when the universe was only a billion years old, and is by some way the strongest signal we have received from that time. The burst of energy came from a quasar located 13 billion light years away. As such, it began its journey when the universe was relatively young.

"This is the most detailed image yet of such a bright galaxy at this great distance," said Emmanuel Momjian, of the National Radio Astronomy Observatory (NRAO). Scientists might now be able to examine the emission to understand more about a time when the universe looked vastly different to how it does today. It might finally allow us to understand the beginnings of the earliest galaxies.
