Two Earth-Size Worlds in TRAPPIST-1 System Reveal Stark Divide Between Day and Night

This artist’s impression shows an imagined view from the surface one of the three exoplanets orbiting the ultracool dwarf star TRAPPIST-1 38.8 light-years from Earth. These alien worlds have sizes and temperatures similar to those of Venus and Earth. In this view one of the inner planets is seen in transit across the disc of TRAPPIST-1. Image credit: M. Kornmesser / ESO.

New Webb observations of two exoplanets TRAPPIST-1b and TRAPPIST-1c show blistering days and frozen nights, offering the first detailed climate maps of rocky exoplanets and dimming hopes for habitability.
