Mysterious radio signals were picked up by Canadian astronomers. The surprise? they were not issued one, but six times. All from the same place: a galaxy located more than 1,500 million light-years away.
No, it's not an exaggeration. Typically, these fast radio or FRB bursts appear temporarily and randomly. That is, without evidence of standards. Therefore, it is difficult to discover them or, even more, to analyze them.
So far only there was a confirmed case of a repeating wave. And, of course, considering that there were now six replicates of the same place, the astronomy world went insane.
Radio signals sent by extraterrestrials?
The power of the FRB is such that in just a few milliseconds they can generate the same energy as the sun.
However, the source of this powerful energy source is still puzzle. In fact, there are scientists who say yes or yes, they come from a place far beyond the Milky Way. There are also those who argue that they are the product of more developed extraterrestrial civilization than our.
And of course, there are many theories about this.
Other experts say that these types of signals come from black holes or of neutron stars with very strong magnetic fields. There are also scientists who point out that this finding evidences the existence of extraterrestrial life.
This is the case of the teacher Avid Loeb, of the Center for Astrophysics at Harvard. The professional postulates that these waves could be evidence of alien technology "very" advanced.
The first FRB
Of course, catching waves in space is nothing new. FRB were detected for the first time in 2007, when the signals were discovered in data obtained in 2001, that is, six years ago.
To date, more than 60 have been captured, although only two of them have been repeated. A fact no less, it draws attention in the scientific world.
The other case of a repeated FRB occurred in 2012, with a wave generated in a galaxy about 2,500 million light years from Earth.
Scientists at the Chime Observatory, located in British Columbia, Canada They worked hard for three weeks. During this time, they were able to capture 13 flashes using a new type of radio telescope.
However, the team of professionals was able to detect, in an unprecedented way, a new repeated wave. "Until now, only one FRB was known and repeated," said Ingrid Stairs, an astrophysicist at Chime, Journal Nature.
"With more repeaters and more sources available for study, we can understand these cosmic puzzles, where are they from and what makes them"he added.
In total, the radio telescope managed to capture 13 explosions, all with signs of "dispersion", except for the "repeated" FRB.
