The source of the cosmic radio explosions was finally discovered



(Reporter)
A moment of luck has helped astronomers solve a cosmic mystery: What causes powerful but fleeting radio explosions that can zigzag in space? According to AP. What’s even more difficult is that they happen so quickly, in just a few milliseconds. Then this April, a rare but significantly weaker explosion that originated from the inside of our Milky Way was detected by two different telescopes: one was the research’s manual antenna set. saving California, the other being a Canadian $ 20 million observatory. They tracked that fast radio blast to a strange star called a magnet 32,000 light years from Earth, according to four studies in the journal Wednesday. nature.

This is not only the first fast radio explosion to originate from a single source, but also the first to emerge from our galaxy. Astronomers say there might be other sources for these explosions, but they̵

According to McGill University astrophysicist Ziggy Pleunis, who co-authored the study, they have gigantic magnetic fields that explode and splutter, and sometimes X-rays and radio waves burst from them. There may be dozens of magnets in our galaxy, and astronomers don’t know how often these explosions occur. Caltech radio astronomer Christopher Bochenek said: “We still don’t know how lucky we were. “This could be something that happens once every five years or maybe a few events every year.”
