A huge explosion of mysterious space radio waves has been traced to the precise location in the galaxy billions of light years


A huge one-time explosion of mysterious space radio waves was precisely located in the galaxy at a distance of 3.6 billion light years.

Powerful wave tremors came from a galaxy in size with the Milky Way, which scientists were able to determine for the first time, using the world's three largest optical telescopes.

"This is a big breakthrough, which awaited this direction, since astronomers in 2007 opened up a quick radio bomb," said Keith Bannister, chief scientist at Australia's National Science Agency.

"If we stood on the Moon and looked at the Earth with such precision, we could say not only which city exploded, but also what zip code and even a block of the city," he said.

The opening was made by an international team led by Australia, which uses the new radio telescope owned by the Australian Scientific Organization (CSIRO).

Astronomers hope that this breakthrough will bring them closer to the cause of the rapid radio bursts that remain unknown, according to a study published in the journal. Science.

Since 2007, only 85 space radio waves have been detected. Most of them are "one-time", but a small number are "repeaters" that are repeated in one place.

Two years ago, astronomers discovered a "repeater" of the home-made galaxy, but this is the first time they exactly find a "one-time" ripple. The rapid bursts of radio stations last less than a millisecond, making it extremely difficult to determine their origin.

The technology used at launch was the Arthritis Pathfinder (ASKAP) Australian Square Kilometer radio telescope.

A member of the group, Dr. Adam Deller of Swinburne University of Technology, Melbourne, said: "The explosion we localized and its main galaxy look not like the" repeater "and its host. It comes from a massive galaxy that forms relatively few stars.

"This indicates that rapid bursts of radio communications can be made in different environments or that seemingly disposable packages still detected by ASKAP are generated by a different repeater mechanism."

ASKAP is a set of antennas, and the explosion had to move at different distances to reach each antenna.

ASKAP managed to freeze and save data less than a second after an explosion (FRB 180924) arrived at a telescope from its home-made galaxy (DES J214425.25? 405400.81).

"From these small differences in time – only for a fraction of a billionth of a second – we determined the home-made galaxy of an explosion and even its precise starting point that came from the center of the galaxy in the galactic suburbs, at a distance of 13,000 light years," said Dr. Doller.

To learn more about the home galaxy, the team understood it in the "Very Large Telescope" of the European Southern Observatory in Chile and measured its distance with the Keck Hawaii Telescope and the Gemini South Telescope in Chile.
