AND Radio signal nearly 9 billion light-years away from Earth was captured in a new image discovered by India’s Giant Metrewave Radio Telescope.
McGill University said in a press release that this is the first time this type of radio signal has been detected at such a great distance. Space.com reported that the signal could mean scientists could begin studying some of the earliest stars and galaxies.
This isn’t the first time scientists have received one mysterious signal from space.
Last July, astronomers from MIT and other universities in the US and Canada discovered a persistent signal from a distant galaxy of unknown astrophysical origin, and in 2020 a mysterious signal from Proxima Centauri was making waves.
But do these signals mean that we are not alone? The answer now is no – although A deliberate signal was sent into space.
That’s what researchers said in 2021, according to Nature the Proxima Centauri signal was likely “man-made radio interference,” and the source of the “Fast Radio Burst” signal has been suggested to be either a radio pulsar or a magnetar, both of which are types of neutron stars.
“There aren’t many things in the universe that emit strictly periodic signals,” said Daniele Michilli, a postdoc at MIT’s Kavli Institute for Astrophysics and Space Research, at the time. “Examples we know of in our own galaxy are Radio pulsars and magnetars, which spin and produce a radial emission similar to a lighthouse. And we think this new signal could be a magnetar or a pulsar on steroids.”
In this latest case, the signal’s properties indicate that it originates from neutral hydrogen gas in a star-forming galaxy named SDSSJ0826+5630.
McGill said so Signal was sent out from the galaxy when the universe was only 4.9 billion years old.
“That’s the equivalent of looking back 8.8 billion years,” Arnab Chakraborty, a postdoctoral researcher at McGill University, said in a statement.
