TRAPPIST 1 flares mapped to probe planetary habitability

Boulder CO (SPX) Dec 05, 2025

TRAPPIST-1, a small star about 40 light-years from Earth in the constellation Aquarius, produces flares roughly six times per day, and this activity complicates efforts to evaluate whether its planets could be habitable.

A team led by the University of Colorado Boulder used NASAs James Webb Space Telescope together with detailed computer simulations to study how these flares arise and how
