Thermal emission measurements from the exoplanet Trappist-1 b suggest two plausible yet contradictory scenarios ...

The TRAPPIST-1 system is a science-fiction writer's dream. Seven Earth-sized worlds orbit a red dwarf star just 40 light-years away. Three of those worlds are within the habitable zone of the star.

This 2018 artist's concept shows what the TRAPPIST-1 planetary system may look like, based on available data about the planets' diameters, masses and distances from the host star (far left).

Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth, but the system is just 40 light-years away and has seven Earth-sized worlds. advertisement Phys.org ...
