![]() What's even more alarming than that this radio signal was able to go undetected for more than three decades is that scientists have not determined with confidence what it could be. Studying records at the Very Large Array in New Mexico, which maintains the longest-running archive of data, the researchers discovered that the source's pulse was first observed in 1988. View Gallery: New images from the James Webb Space Telescope look deep into universe Within no time, a new source was discovered in a different part of the sky, this time repeating every 22 minutes with five-minute pulses. They didn't have to wait long to find what they were looking for. ![]() The team of astronomers used the Murchison Widefield Array radio telescope in Western Australia to scan the Milky Way galaxy every three nights for several months. So they looked again, knowing that the chance was high they would find another long-term radio source. But by the time they analyzed the data in 2020, it was no longer producing radio waves, according to Hurley-Walker. ![]() Using data gathered in 2018, astronomers first detected another magnetar spinning much slower than usual and sending similar signals every 18 minutes. Natasha Hurley-Walker said in a statement on ICRAR's website.Īlien technology? Harvard professor finds fragments that could be of otherworldly origin First signal detected from 2018 data “This remarkable object challenges our understanding of neutron stars and magnetars, which are some of the most exotic and extreme objects in the universe,” lead author Dr. Believed to be coming from around 15,000 light years away from Earth, the signal has been occurring at intervals and for a period of time previously thought to be impossible. The discovery of the signal, which researchers named GPMJ1839-10, has the scientists baffled. That's what Curtin University astronomers from the International Centre for Radio Astronomy Research ( ICRAR) concluded in research published last week in the journal Nature. The much nearer star, L 1159-16, which is one of the nearest 40 stars to the Sun, is near the signal's position, but its proximity is likely coincidental.Mysterious radio wave pulses from deep in space have been hitting Earth for decades, but the scientists who recently discovered them have no concrete explanation for the origin of the signals.įor 35 years, the strange blasts of energy in varying levels of brightness have occurred like clockwork approximately every 20 minutes, sometimes lasting for five minute intervals. All of these stars are red dwarfs much less massive than the Sun. The closest star systems in the approximate region of the signal include the binary star G 73-11A and B, which are 106.1 light-years from the Sun, although the unrelated star G 73-10 is only 108.7 light-years away, less than three light-years from G 73-11A and B. The region is unusually devoid of any nearby stars. It could be an artifact of random chance, cosmic noise or even a glitch in the technology. has denied media reports of a likely extraterrestrial intelligence signal. There are a number of potential explanations for this signal. Each time the signal was detected, it was again at about 1420 MHz, the original frequency before any drift. If the cause is Doppler shift, it would indicate emission from a planet rotating nearly 40 times faster on its axis than the Earth. The frequency of the signal has a rapid drift, changing by between 8 and 37 hertz per second. ![]() The source is located between the constellations Pisces and Aries, a direction in which no stars are observed within 1000 light years from Earth. There are a number of puzzling features of this candidate, which have led to a large amount of skepticism. It was observed three times (for a total of about one minute) at a frequency of about 1420 MHz, one of the frequencies in the waterhole region, which is theorized to be a good candidate for frequencies used by extraterrestrial intelligence to broadcast contact signals. The source was originally detected by Oliver Voelker of Logpoint in Nuremberg, Germany and Nate Collins of Farin and Associates in Wisconsin, USA using the giant Arecibo Telescope in Puerto Rico. SHGb02+14a is an astronomical radio source and a candidate in the Search for Extra-Terrestrial Intelligence (SETI), discovered in March 2003 by and announced in New Scientist on September 1, 2004.
