A little luck will help astronomers solve a mystery in space: What is the cause of the powerful but super-fast energy Raja signs moving in the universe?
Scientists have known about these signals for about 13 years, which is called rapid radio bursts. And they have seen them coming from outside us Galaxy. This makes it difficult for them to know what the reason is. What makes it even harder is that it happens so quickly – in a few thousandths of a second.
Then in April, a rare but very weak explosion from inside our own galaxy, found by two different telescopes. One of the binoculars was a hand-made device from a California doctoral student, which included metal cookware. The other was based on the 20 200 million Canadian Space Observatory.
They linked the rapid radio explosion to a strange type of star called a magnetar that is 32,000 light-years from Earth. That information comes from Wednesday’s four studies Journal Release Nature.
It’s not just the first rapid radio explosion that h Source; It was also the first to come out of our galaxy. Astronomers say there may be other sources for these explosions. But now they are sure about one of the sources: magnets.
Magnets are 1.5 times the number of our suns, filling the space the size of the Manhattan area of New York. They have huge magnetic fields that are filled with energy rays, and sometimes they explode X-ray And suddenly radio waves come from them. That information comes from Zigly Plains. He is an astrophysicist at McGill University and co-author of Canadian Studies.
Astronomer Casey Lowe said the magnetic field around the magnet was “so strong that any nearby atom would fall apart.” It is affiliated with the California Institute of Technology (Caltech) and is not associated with research.
Our galaxy will probably have 12 or more magnets. They are very young and part of the star birth process. And our galaxy is not full of stars like other galaxies, said Shami Chatterjee of Cornell University. They were not both part of the search team.
These eruptions in less than a second produce as much energy as our sun in a month. “It’s still much weaker than hitting the radio outside our galaxy,” said Christopher Bochenek. The radiotech radio astronomer helped detect the explosion with his hand-made devices.
Astronomers say radio explosions are not dangerous to us, nor are they more powerful outside the galaxy.
Coming from outside our galaxy and traveling millions of light-years is very powerful. Daniel Mitchell, an astrophysicist at McGill University, explains that it is thousands to millions of times more powerful than anything we find in our galaxy. He is the co-author of the study and part of the Canadian team.
Scientists believe that airplanes can fly out of our galaxy more than 1000 times a day. But finding them is not easy.
“You had to look at the right place in the right milliseconds,” Cornell Chatterjee said. “Unless you’re very lucky, you won’t see any of this.”
Astronomers have no idea how often explosions occur inside our own galaxy.
“We still don’t know how lucky we are,” Bochenek said. “This could be a five-year thing in a year or some of the events that happen every year.”
Of Bochenek Antenna Cost of about 15,000. Each is a “large size.” Bucket“He said.” It’s a one-inch piece of metal pipe surrounded by two pieces of round metal cookware, the doctoral student explained. They are simple tools designed to see a wide part of the sky. And it’s just a bright radio flush to watch.
Bochenek speculates that he has a 1-in-10 chance of a fast radio explosion in a few years. But just a year later, he made a valuable discovery.
The Canadian Observatory in British Columbia is more developed but has been built keeping in mind many small pieces of the sky. And he could find the source of the magnet Constellation Valpecula.
All the material they pass through is affected by the explosion. This could help astronomers understand and map the unseen material between “weighing” galaxies and the universe, Jason Hassells said. He is the chief astronomer at the Netherlands Institute for Radio Astronomy and was not part of the research.
Astronomers have come up with about 50 different ideas about what caused this rapid radio explosion, including Aliens. They say magnets just may not be the answer.
