Examples we know in our galaxy are radio and magnetic pulsars, which spin and emit a beacon. What exactly would this evidence be? Neutron stars, two types of neutron stars with more dense and faster-spinning cores than giant stars, remain a mystery, although astronomers suspect that the signal may be emitted by a radio pulsar or magnetar.ĭaniel Michael, a postdoctoral researcher at MIT’s Kavli Institute for Astrophysics and Space Research and lead author of the study, explains that periodic signals like this only come from a limited number of astronomical events. The source of the signal is in a galaxy billions of light years away from Earth. The researchers have named the signal observed in the study FRB 20191221A, and it is the longest-lived FRB with the clearest periodic pattern detected to date, as these bursts usually disappear and are not regular.

This signal consists of four consecutive four-day random bursts, then repeated every 16 days. Researchers have finally discovered the first-ever fast radio burst that emits a regular pattern of radio waves, so it’s not a flash that fades away forever. Most fast radio bursts observed so far are one-off, that is, ultra-bright bursts of radio waves that last a few milliseconds before flashing. The telescope is sensitive to fast radio bursts, and since it began observing the sky in 2018, it has detected Telescope Hundreds of fast radio bursts from different parts of the sky. CHIME continuously monitors the sky as Earth rotates, and is designed to capture radio waves emitted by hydrogen in the early stages of the universe’s life. Since the discovery of the first fast radio burst in 2007, hundreds of similar radio flashes have been observed across the universe, most recently by the Canadian Hydrogen Intensity Mapping Experiment, or CHIME, and most recently by radio telescopes measuring interferometry in the Four Large Parabolic Reflectors. study Published July 13 in the journal Nature. In this window, the team detected bursts of radio waves with a distinct periodic pattern every 0.2 seconds, similar to a heartbeat, according to their findings. However, this new signal lasts up to three seconds, a thousand times longer than the average FRB, and is one of the longest-lasting signals ever. The signal is classified as a fast radio burst (FRB), a very strong burst of radio waves of unknown astrophysical origin, typically lasting a few milliseconds. ![]() Find out Scholars Astronomers at the Massachusetts Institute of Technology and other astronomical research centers have detected a strange, steady radio signal from a distant galaxy flashing with surprising regularity.
