Radio signal 9 billion light-years away: What it means and where it came from

Webb Space Telescope allows us to look into the past: Theoretical physicist

Theoretical physicist Dr. Michio Kaku explains the significance of new images provided by NASAs Webb Space Telescope on Sunday Night in America.

Aradio signal nearly 9 billion light-years awayfrom Earth was captured in a new recording, detected by Indias Giant Metrewave Radio Telescope.

McGill University said in a release that this marked the first time this type of radio signal has been detected at such a large distance. reported that the signal could mean scientists can start investigating some of the earliest stars and galaxies.

This is not the first time scientists have received amysterious signal from outer space.

Last July, astronomers at MIT and other universities in the U.S. and Canada detected a persistent signal from a distant galaxy of unknown astrophysical origin and in 2020 a mysterious signal from Proxima Centauri made waves.

RADIO SIGNAL FROM 9 BILLION LIGHT-YEARS AWAY FROM EARTH CAPTURED

But, do these signals mean were not alone? The answer right now is no althoughan intentional signal has been sent to space.

Researchers said in 2021, according to Nature, thatthe Proxima Centauri signalwas likely human-made radio interference and the source of the fast radio burst signal was suspected to be either a radio pulsar or a magnetar, both of which are types of neutron stars.

There are not many things in the universe that emit strictly periodic signals, Daniele Michilli, a postdoc in MITs Kavli Institute for Astrophysics and Space Research, said at the time. Examples that we know of in our own galaxy areradio pulsars and magnetars, which rotate and produce a beamed emission similar to a lighthouse. And we think this new signal could be a magnetar or pulsar on steroids.

In this most recent case, properties of the signal indicate that it came from gaseous neutral hydrogen in a star-forming galaxy named SDSSJ0826+5630.

McGill said thesignal was emitted from the galaxywhen the universe was only 4.9 billion years old.

Its the equivalent to a look-back in time of 8.8 billion years, Arnab Chakraborty, a Post-Doctoral Researcher at McGill University, said in a statement.
