Mysterious signals from 1000 light years away

Click For Summary
In February 2003, astronomers using the Arecibo telescope targeted 200 areas of the sky to investigate previously detected unexplained radio signals. After analyzing the data, most signals were found to have vanished, except for one that has intensified. This persistent signal raises questions about its origin and potential implications for extraterrestrial intelligence. The findings contribute to ongoing research in the field of SETI. The mystery surrounding this stronger signal continues to intrigue astronomers and researchers alike.

In February 2003, astronomers involved in the search for extraterrestrial intelligence (SETI) pointed the massive radio telescope in Arecibo, Puerto Rico, at around 200 sections of the sky.

The same telescope had previously detected unexplained radio signals at least twice from each of these regions, and the astronomers were trying to reconfirm the findings. The team has now finished analysing the data, and all the signals seem to have disappeared. Except one, which has got stronger.

Thread 'Luminous Fast Blue Optical Transients (LFBOTs)'

UC Berkely, December 16, 2025 https://news.berkeley.edu/2025/12/16/whats-powering-these-mysterious-bright-blue-cosmic-flashes-astronomers-find-a-clue/ AT 2024wpp, a luminous fast blue optical transient, or LFBOT, is the bright blue spot at the upper right edge of its host galaxy, which is 1.1 billion light-years from Earth in (or near) a galaxy far, far away. Such objects are very bright (obiously) and very energetic. The article indicates that AT 2024wpp had a peak luminosity of 2-4 x...
