NASA astronomers have discovered an unexpected “signal” coming from outside our galaxy. This signal was accidentally detected while scientists were analyzing 13 years of data from the Fermi gamma-ray space telescope.
This advanced telescope can detect gamma rays, which are huge bursts of energetic light. Gamma rays are often created when stars explode or nuclear explosions occur.
An article explaining these findings was published Wednesday (10/1/2024) in The letters from the astrophysics diary.
Initially the researchers looked for the oldest gamma rays

Researchers are looking for one of the oldest features of gamma rays to create the first atom. These rays are known as the cosmic microwave background, or CMB.
Instead of finding CMB rays, the researchers detected a signal coming from the same direction as another unexplained feature. This signal contains some of the most energetic cosmic particles they have ever detected.

“We found a much stronger signal and in a different part of the sky than we were looking for.” wrote Francis Reddy from NASA’s Goddard Space Flight Center Thursday (1/11/2024).
