The potentially habitable exoplanet Trappist-1 has been discovered destroying its atmosphere

Scientists have discovered that a potentially habitable planet has had its atmosphere stripped away, a process that could eventually render the world, Trappist-1e, uninhabitable. The abstraction appears to be caused by electrical currents that arise as the planet races around its red dwarf host star.

It's an important discovery because the Trappist-1 system, in which this exoplanet orbits a small red dwarf star, has been one of the primary targets in the search for alien life. Of the seven rocky, Earth-like worlds in the system, at least three are in the habitable zone, a region around a star that is neither too hot nor too cold to allow a planet to support liquid water.
