Quasar blast is the largest ever recorded by astronomers

Quasar blast is the largest ever recorded by astronomers says a new analysis.

The quasi-stellar radio source, or "quasar," created a blast two trillion times more powerful and 400 times larger than the Sun.

The energy beam is apparently moving at 18 million miles per hour and has already fired nearly 1000 light years beyond its starting point.

Quasars were once believed to be similar to stars but in fact they are blasts of energy emanating from black holes in newly forming galaxies, said AFP.

"We discovered the most energetic quasar outflow ever seen, at least five times more powerful than any that have been observed to date," said study co-author Nahum Arav, of Virginia Tech, according to National Geographic.

"We were hoping to see something like this, but the sheer power of this outflow still took us by surprise," he added.

Quasars tend to be so far away and take so long to reach Earth's telescopes that they are considered to be glimpses into the ancient history of the universe, reported AFP.

It is the first time that quasar energy output has been measured at levels that only existed in theory.

Quasars are the brightest and most distant objects ever found in the universe.

The latest quasar was detected by the European Southern Observatory's Very Large Telescope, which is based in Chile.

Space.com said that the discovery could answer the question as to why black holes in new galaxies are so bright.

The finding will be published in The Astrophysical Journal.
