Scientists think life might survive on Proxima b, in spite of powerful lashings from its host star.
Although the flare lasted just 10 seconds, it made the star appear about 1,000 times brighter than usual.
Cold dust has never been so intriguing.
Scientists showed the potential habitability of the planet under different atmospheric conditions and orbits using a state-of-the-art model.
