12/5/2023 0 Comments Strange radio signal from space![]() ![]() The team haven’t proved any of these signals are from exoplanets, but after weighing the possible explanations of the strange radio signals, they consider exoplanets a good bet for four of the stars, Callingham says. If you could turn your eyes into radio antennae, when you looked into the sky, “you would not see stars, generally,” Callingham says, “you’d see the sun a little bit, you’d see Jupiter really bright, and you would see mostly galaxies.” Stars aren’t very bright in radio frequencies. ![]() He and his colleagues used a massive radio telescope called the Low Frequency Array or LOFAR to look at nearby red dwarfs in radio frequencies, and published their findings in the journal Nature Astronomy. © 2023 NYP Holdings, Inc.A team of astronomers found 19 strange radio signals from red dwarf stars, four of which they think could be coming from orbiting exoplanets, potentially marking the first time exoplanets have been discovered using radio frequencies.ĭetecting these stars wasn’t a big deal-they were all relatively close to Earth and the team compared the detections with existing optical observations-but “discovering them in radio was a big deal,” because they shouldn’t be bright in radio frequencies, says Joe Callingham, a radio astronomer at Leiden University in the Netherlands and lead author of the study. The repeating sources of FRBs are providing criteria that is “uniquely valuable to astronomers” in the sense that the source can be reobserved in greater detail. ![]() Pleunis said it has “an edge over other telescopes when it comes to discovering FRBs.” New pieces of data point to some of the radio signals possibly being connected to one another.Īdvancements in this technology have also made Earth’s top minds more privy to what is coming our way.ĭevelopment of the CHIME telescope - which can capably scan the northern sky each day - has also led to an increased rate of interception “from a few tens, to thousands in recent years,” according to researchers. “We can now accurately calculate the probability that two or more bursts coming from similar locations are not just a coincidence,” Dr. In their newly published research, it was discovered that a portion of the mysterious FRBs were not random signal emissions, said study author Dr. “One of the big questions is whether the repeating FRBs and those that don’t repeat have similar origins.” “Most of the thousands of FRBs that astronomers have discovered to date have only ever been seen to burst once, but there is a small subset that have been seen to burst multiple times,” according to the collaboration. CHIME/FRB/Luka VlajiÄ.Īlien life is most likely to exist in these star systems: scientists The CHIME telescope has played a major role in detecting radio signals. These FRBs are, according to the scientific CHIME/FRB collaboration, “considered one of the biggest mysteries in astronomy,” but it is confirmed that they came from outside the Milky Way galaxy. The project uses a high powered radio telescope in British Columbia to receive the signals. Recently detected were 25 new repeating sources, known technically as fast radio bursts, from the depths of the universe, the Canadian Hydrogen Intensity Mapping Experiment reported. Thousands of deep space radio signals have made their way to Earth - 50 of them from repeating sources, according to Canadian astronomers monitoring what could possibly be alien contact from another world.
