a The radio signal is approximately 9 billion light-years away It was captured from Earth in a new recording, discovered by India’s Giant Metrewave Radio Telescope.
McGill University said in a statement that this is the first time that this type of radio signal has been detected at such a large distance. Space.com reported that the signal could mean that scientists can start investigating some of the oldest stars and galaxies.
This is not the first time that scientists have received a file A mysterious signal from outer space.
Last July, astronomers at MIT and other universities in the United States and Canada detected a continuous signal from a distant galaxy of unknown origin in astrophysics, and in 2020 a mysterious signal from Proxima Centauri made waves.
But, do these signs mean we are not alone? The answer now is no – though An intended signal has been sent into space.
Researchers in 2021, according to Nature, said so Proxima Centauri signal It was likely “man-made radio interference” and the source of the “fast radio burst” signal was suspected to be either a radio pulsar or a magnetar, both types of neutron stars.
“There aren’t many things in the universe that emit strictly periodic signals,” Daniel Micheli, a postdoctoral researcher at MIT’s Kavli Institute for Astrophysics and Space Research, said at the time. Examples that we know of in our galaxy are Radio and magnetic pulsars, which rotates and produces a beacon-like emission. We think this new signal could be a magnetar or a pulsar on steroids.”
In this latter case, the signal’s properties suggest it came from neutral gaseous hydrogen in a star-forming galaxy called “SDSSJ0826+5630.”
McGill said A signal was emitted from the galaxy When the universe was only 4.9 billion years old.
“It’s the equivalent of looking back in time 8.8 billion years,” Arnab Chakraborty, a postdoctoral researcher at McGill University, said in a statement.
