Astronomers discover "weird" Neptune-like exoplanet that could have water clouds

Astronomers have spotted a planet just 90 light years away from Earth with a surprising atmosphere — and the possibility of clouds containing water. 

TOI-1231 b is an exoplanet, meaning it is located outside of our solar system. It was discovered by a team of scientists from NASA's Jet Propulsion Laboratory and the University of New Mexico, who will publish their findings in an upcoming issue of The Astronomical Journal.  TOI-1231 b was detected using data from the Transiting Exoplanet Survey Satellite (TESS) and confirmed using the Planet Finder Spectrograph (PFS) on the Magellan Clay telescope in Chile. The PFS revealed details about the mass and orbits of the exoplanet by observing its gravitational influence on its host star.
