Scientists discover EIGHT new mysterious radio impulses that come from outer space and could help uncover their origins

  • In Canada, scientists have discovered new repetitive radio bursts
  • The new findings could help to solve the mystery of the origin of space signals
  • With the eight new discoveries, the total number of known repeaters is 11
  • The discovery will provide more insight into the first tracked signal found in June

Scientists have found eight more mysterious, repetitive radio bursts from outer space that more than quadruple the number of signals from early this year.

The new signals were found by the Canadian Radio Telescope CHIME (Hydrogen Intensity Mapping Experiment) and give scientists a much broader set of data that they hope will help unlock their origins.

With the discovery described in an article in The Astrophysical Journal Letters, the number of repeating radio signals has increased to eleven.

The new signals will help scientists in their efforts to detect the origin and cause of mysterious radio bursts from space.

According to Nature, the results of a separate observation by researchers in Australia are yet to be published, but the number of results this month alone is nine.

The recent findings have not only increased the amount of data for astronomers, but are also important for the type of identified radio bursts.

The signals described by the researchers are repeating, which means that they can be examined over a longer period of time, as opposed to their unique counterparts, which go in and out after only a single detection.

Due to the transitoriness of the latter, it was an extremely difficult, if not completely impossible, task to determine its origin.

In a previously unprecedented effort, scientists were following a one-off radio hit that originated last month.

According to an Australian-led team operating from the Gemini South telescope in Chile, the signal was traced back to a galaxy some 3.6 billion light-years distant.

The recent increase also means that scientists can begin to compare and contrast the signals and test new theories.

Last month, in a publication by Harvard-Smithsonian astrophysicist Vikram Ravi, the scientist speculated that all bursts could actually recur, only at frequencies not previously captured.

"Just as some volcanoes are more active than others, and you can believe that a volcano is dormant because it has not erupted in a long time," physicist Ziggy Pleunis of McGill University told ScienceAlert.

Scientists have already noticed a difference between the repeaters and their unique iterations. For example, the frequencies of repetitive signals decrease, so that scientists speak of a "sad trombone effect".

This month, a machine learning technique will be introduced that will help scientists solve the puzzle and automatically pick up the explosions as they reach Earth.

WHAT ARE FAST RADIO INTERFERENCE AND WHY DO WE STUDY YOU?

Fast Radio Bursts (FRBs) are radio transmissions that occur transiently and randomly, making them not only hard to find, but difficult to investigate.

The mystery stems from the fact that it is not known what could cause such a short and sharp outburst.

This has led some to speculate that it could be anything from stars colliding to artificially generated messages.

Scientists looking for fast radio bursts (FRBs), some of which believe they are extraterrestrial signals, may happen every second. The blue dots in the artist's impression of the filamentous structure of galaxies spanning the entire sky are signals of FRBs

The first FRB was discovered by radio telescopes in 2001, or rather "heard", but was only discovered in 2007 when scientists analyzed archive data.

But it was so transitory and seemingly random that it took years for the astronomers to agree that there was no glitch in one of the telescope's instruments.

Researchers at the Harvard-Smithsonian Center for Astrophysics point out that FRBs can be used to study the structure and evolution of the universe, whether or not its origin is fully understood.

A large population of distant FRBs could function as a material probe over gigantic distances.

This intervening material blurs the cosmic microwave background (CMB) signal and the remaining Big Bang radiation.

A careful examination of this intervening material should allow for a better understanding of the basic cosmic constituents, such as the relative amounts of ordinary matter, dark matter, and dark energy, which affect how fast the universe expands.

FRBs can also be used to keep track of what the & # 39; fog & # 39; from hydrogen atoms that permeated the early Universe into free electrons and protons as the temperatures cooled after the Big Bang.
