TEMPO.CO, Jakarta – Astronomers have long struggled to translate signals from radio waves to outer space. Some suspect that the signal came from extraterrestrials who tried to communicate. Now, astronomers are looking for the source of this signal using artificial intelligence or AI.
Per page Science of lifeRecently, astronomers hope to discover immediately why the signal sent to Earth has been sent, and researchers suspect that the distance is several billion light years in space. The signals have complex and mysterious structures, patterns of peaks and valleys in radio waves that are only read in milliseconds.
Until now, the signal source is not expected from a simple explosion or other standard events known to propagate overvoltages of electromagnetic energy in space . Astronomers call this strange signal fast radio burst (FRB).
Since its discovery in 2007 based on data recorded in 2001, constant efforts have been made to determine the source. However, the FRB arrived at random times and places, and existing human technology and observation methods were not ready to find these signals.
In an article published in a newspaper Monthly Notices from the Royal Astronomical Society, The team of astronomers wrote that she had managed to detect five FRBs in real time with the aid of a single radio telescope.
Wael Farah, a PhD student at Swinburne University of Technology in Melbourne, Australia, developed a machine learning system that recognizes the FRB sign when he arrives at the Molonglo University Radio Observatory in Sydney, near from Canberra. As reported Science of life Previously, many scientific instruments, including radio telescopes, produced more data per second than they could reasonably store.
They do not record anything in the slightest details, except for their most interesting observations. The Farah system allows the Molonglo telescope to recognize FRB and switch to its most detailed recording mode, and produce the best FRB recordings.
On the basis of their data, the researchers estimate that between 59 and 157 detectable FRBs are theoretically distributed daily in the sky. Scientists also use direct detection to hunt flare related to X-ray data, optical and other radio telescopes. The hope is to be able to find some events related to the FRB, but no luck.
However, their research shows that one of the strangest (and frustrating, search-oriented) features of FRB seems real: once the signal arrives, it never repeats itself. Each seems to be a unique event in the space that will never happen again.
