Scientists have picked up radio signals in a galaxy billions of light-years away: NPR

This image released by NASA on Tuesday, July 12, 2022, combined the capabilities of the two cameras of the James Webb Space Telescope to create an unprecedented view of the star-forming region of the Carina Nebula. Taken in infrared light by the Near Infrared Camera (NIRCam) and the Medium Infrared Instrument (MIRI), this image reveals previously unseen regions of star birth.

MIT astronomers have repeatedly captured Radio signals from a galaxy billions of light-years away from Earth.

Scientists have not been able to determine the exact location of the radio waves yet, but they suspect that the source may be neutron stars, which are made from the collapsed cores of giant stars.

The signals were occurring steadily and lasting for up to three seconds, the researchers say. Most fast radio bursts, or FRBs, last only a few milliseconds.

“During this window, the team detected bursts of radio waves that repeat every 0.2 seconds with a distinct periodic pattern, similar to a heartbeat,” MIT said. statement.

On December 21, 2019, researchers at the Dominion Radio Astrophysics Observatory in British Columbia, Canada, picked up a signal from a possible FRB, according to an MIT statement.

said Danielle Mitchell, a postdoctoral researcher at MIT’s Kavli Institute for Astrophysics and Space Research. “This is the first time that the same signal has been periodic.”

Data about the bursts, including their frequency and how they change based on the source’s location near Earth, can help researchers determine the speed at which the universe is expanding.
