Found “radio waves” in space caused by the phenomenon “A rapid burst of radio waves,” but the latest wave found took 8 billion years to travel to Earth! Astronomers have detected a phenomenon known as “Fast Radio Blast (FRB)” that took 8 billion years to reach Earth This is one of the most mysterious, distant, and powerful explosions ever seen. The definition of an FRB is a millisecond-long burst of intense radio waves of unknown origin. It was first discovered in 2007 and has been around ever since. Hundreds of FRBs have been detected from far-flung locations across the universe. James Webb discovers nanoquartz in the atmosphere of an exoplanet. New images from James Webb may lead to the discovery of an astronomical object. new type The discovery of extraterrestrial life It may be possible in the next few years. The explosion that excited astronomers, dubbed FRB 20220610A, lasted less than 1 millisecond. But during that time, They emit energy equivalent to the energy released by our sun over the course of 30 years. Many FRBs emit ultra-bright radio waves that last only a few milliseconds before disappearing. This makes it difficult to observe such radio bursts. But with a radio telescope It can help astronomers keep track of these rapid phenomena. including the ASKAP radio telescope located in Wajarri Yamachi in Western Australia. Australia’s ASKAP detected the FRB 20220610A explosion in June 2022 and is trying to figure out how. Where does it come from? Dr. Stuart Ryder, astronomer from Macquarie University in Australia One of the researchers who made the discovery said: “Using ASKAP’s radio dish we were able to pinpoint precisely where the explosion came from.” He added: “We then used the European Southern Observatory’s (ESO) Very Large Telescope. in Chile to search for the source galaxy and found it to be older and more distant than any other FRB found to date. It likely resided within a small group of galaxies that joined together.” The team traced the explosion to what appeared to be two or three galaxy clusters in the process of merging to form new stars. This finding is consistent with current theories that suggest that Rapid bursts of radio waves can come from magnetic fields or energetic objects resulting from stellar explosions. Scientists believe that Rapid bursts of radio waves may be a unique method that can be used to Scientists have been able to “weigh” the universe by measuring unidentified matter between galaxies, says Ryan Shannon, a professor at Swinburne University of Technology in Australia. Another team member said: “If we counted the amount of normal matter in the universe, we would find that more than half of what should be present is missing.” He added, “We think that the missing matter is hiding. In the space between galaxies But it might be so hot and diffuse that it cannot be seen using normal techniques.” So far, results from current methods used to estimate the mass of the universe have been inconsistent. shannon said “A rapid burst of radio waves is felt by this ionized material. Even in space that is almost completely empty They can also ‘see’ all electrons. And that allows us to measure how much matter is between galaxies.” The method uses rapid bursts of radio waves to detect this missing matter. This was previously demonstrated by Australian astronomer Jean-Pierre Maggarte, who passed away in 2020. Ryder said: “Jean-Pierre showed that The faster (far) the radio burst is, the more gas will be scattered between galaxies. which we currently call Maggart Relations But the recently discovered bursts of radio waves appear to break this relationship.” In the past, nearly 50 bursts of radio waves have been successfully traced back to their origins. “While we still don’t know what causes these enormous bursts of energy, But the report confirmed that Rapid bursts of radio waves are a common event in the universe. And we will be able to use it to detect intergalactic matter. and understand the structure of the universe,” said Shannon. They hope that future radio telescopes It is currently under construction in South Africa and Australia. It will allow the detection of thousands of more rapid bursts of radio waves over ever longer distances. “You won’t just do this 30 times, you can do this 30,000 more times, creating a new map of the structure of the universe. and use it to answer important questions regarding cosmology,” said Shannon.
