Planets in the TRAPPIST-1 system

An international team of astronomers used the Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1.

The results suggest that the outer planets of the system might still harbor substantial amounts of water. This includes the three planets within the habitable zone of the star, lending further weight to the possibility that they may indeed be habitable.
