Original title: Hotspot | The secret of space! Where is the mysterious radio wave in the depths of the universe?

Foreign media say that astronomers have said that the astronomical telescope in Canada has detected radio waves from space. However, the source and nature of radio waves are still unclear.

According to a report on the BBC's website on January 10, 13 "high-speed radio waves" were detected from the same source, 1.5 billion light-years from Earth, and the second time the Earth received the same type of record. Rapid radio wave propagation. "

"We know this is not a single event, and that more space waves of the same kind will be in space," said Stales, astrophysicist at the University of British Columbia.

"If we receive more radio waves, we will have more information for studying and solving the secrets of space."

"We have found that the second wave of cyclic waves by characteristics is very similar to the first wave of circulating waves," said Tandoora.

"Rapid radio outbursts" are short, bright waves and scientists now believe that waves come from somewhere in the universe.

According to reports, scientists have so far received about 60 "fast radio waves" and two "cycles".

They believe that there are thousands of "fast radio waves" on the Earth every day, and there are various theories explaining the reasons for "high-speed radio waves," including "combining two neutron stars" and "neutron stars". Rapid rotation in a strong magnetic field "and some people are thinking about an" outer space spacecraft ".

According to France Presse, which reported on January 9, Canadian astronomers discovered mysterious radio waves outside the Rimska cesta. However, it is still unclear which strong waves come from which corner of the universe and how they produce it.

According to the report, this repeated high-speed radio storm was discovered in the telescope test in the summer of 2018. The specially-built telescope showed only a small part of the design capacity.

"At the end of the year, we will be able to find 1000 outbreaks," said Deborah Goode, a doctoral student at the University of British Columbia, one of 50 scientists who took part in the study.

The flash of the rapid radio burst only lasts a moment, but releases the energy that the sun emits within 10,000 years.

What causes the emergence of these high-energy long waves at the far end of the electromagnetic spectrum is still a hot topic.

Since 2007, there have been more than 60 high-speed radio outbreaks, but only once – observed at the Arecibo Observatory in Puerto Rico in 2012 – repeated high-speed radio eruptions.

"Rapid radio outbursts appear to occur in the dense, turbulent regions of the host galaxy," said the author of two research articles, an astronomer from McGill Shriash Tendukal University.

Cosmic gusts caused by turbulent gas clouds that cause stars or star explosions, such as supernovae, can be incubators for rapid radio outbursts, but continuing radio bursts are a special case.

"The fact that repetitive radio eruptions exclude a catastrophic source model that has been destroyed during the explosion," Tendukal said.

It is not clear whether the source of recurrent radio outbursts is different from that where only one radio storm is created.

It should be noted that repeated bugs in 2012 and 2018 have remarkable similarities.

CHIME has also discovered more than a dozen individual radio outbursts but has unusual features.

Most of the rapid radio bursts discovered so far have a wavelength just a few centimeters, but the frequency of these radio outbreaks discovered by CHIME is nearly 1 meter, opening new research guidelines to astronomers.

Will these mysterious radio waves show the other wisdom in the universe? Is it possible that they are some sort of information?

Tendukal said: "This option is extremely small. As a scientist I can not completely exclude this possibility. However, every astronomer will not understand intelligent life as the source of these rapid radio bursts."

CHIME, built in British Columbia, is composed of four 100-meter semiclass metal columns that reconstruct the sky image by processing radio signals recorded by more than 1,000 antennas.
