Universe TodayReviving SETI with High-Energy AstronomyWhat new methods can be developed in the search for extraterrestrial intelligence (SETI)? This is what a recent white paper submitted to the 2025 NASA Decadal Astrobiology Research and Exploration Strategy (DARES) Request for Information (RFI) hopes to address as a pair of researchers from the Breakthrough Listen project and Michigan State University discussed how high-energy astronomy could be used for identifying radio signals from an extraterrestrial technological civilization, also called technosignatures. This study has the potential to help SETI and other organizations develop novel techniques for finding intelligent life beyond Earth.

Clingy planets can trigger own doom, suspect #Cheops and #TESS

"planet with a death wish" seems to be triggering flares of radiation from the star it orbits. These tremendous explosions are blasting away the planet’s wispy atmosphere, causing it to shrink every year.
Though it was theorised to be possible since the 90s, the flares seen in this research are around 100 times more energetic than expected.

EurekAlert!Clingy planets can trigger own doom, suspect Cheops and TESSAstronomers using the European Space Agency’s Cheops mission have caught an exoplanet that seems to be triggering flares of radiation from the star it orbits. These tremendous explosions are blasting away the planet’s wispy atmosphere, causing it to shrink every year. This is the first-ever evidence for a ‘planet with a death wish’. Though it was theorised to be possible since the nineties, the flares seen in this research are around 100 times more energetic than expected.

Astronomers have caught an #exoplanet that seems to be triggering flares of radiation from the #star it orbits.

These tremendous explosions are blasting away the #planet's wispy #atmosphere, causing it to shrink every year.

This is the first-ever evidence of a "planet with a death wish."

Though it was theorized to be possible since the nineties, the flares seen in this research are around 100 times more energetic than expected.
