Stellar flares may hamper search for life in promising star system

Some planets are formed that they have life. But only exoplanets tend not to have it. The latest case is the Trappist 1 saga which probably has none.

Astronomers have been trying to detect atmospheres on planets orbiting TRAPPIST-1, but bursts of radiation from the star make this challenging.

The search for atmospheres around the TRAPPIST-1 star system, one of the most promising locations for life elsewhere in the galaxy, might be even more difficult than astronomers first thought because of short-lived radiation blasts from the star.

TRAPPIST-1, first discovered in 2016, is a small red dwarf star about 40 light years from Earth with at least seven planets orbiting it. It is a prime target for astronomers hoping to detect extraterrestrial life because several of its planets appear to sit in a habitable zone where temperatures are just right for liquid water.
