This image released by NASA on Tuesday, July 12, 2022 combined the capabilities of the James Webb Space Telescope’s two cameras to create a never-before-seen view of a star-forming region in the Carina Nebula. Captured in infrared light by the Near Infrared Camera (NIRCam) and Mid Infrared Instrument (MIRI), this combined image reveals previously invisible star birth zones.

Massachusetts Institute of Technology astronomers spotted repeating problems radio signals from a galaxy billions of light years from Earth.

Scientists have not yet been able to pinpoint the exact location of the radio waves, but suspect the source could be neutron stars, which are made up of the collapsed cores of giant stars.

The signals occur regularly and last up to three seconds, the researchers said. Most fast radio bursts, or FRBs, last only a few milliseconds.

“In this window, the team detected bursts of radio waves that repeat every 0.2 seconds in a clear periodic pattern, similar to a beating heart,” MIT said in a statement.

On Dec. 21, 2019, researchers at the Dominion Radio Astrophysical Observatory in British Columbia, Canada, detected a signal from a potential FRB, according to the MIT release.

“Not only was it very long, lasting about three seconds, but there were periodic peaks that were remarkably precise, emitting every fraction of a second – boom, boom, boom – like a heartbeat,” said Daniele Michilli, a postdoctoral fellow at the Kavli Institute for Astrophysics and Space Research at the Massachusetts Institute of Technology. “This is the first time that the signal itself is periodic.”

Data on the bursts, including their frequency and how they change based on the location of the source near Earth, could help researchers determine how fast the universe is expanding.

The announcement of the repeating radio signals follows the release earlier this week of the first images of the universe from the James Webb Space Telescope. These images reveal galaxies formed more than 13 billion years ago.
