In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface–is an exciting discovery in the search for life on other worlds. There is the possibility that future study of this unique planetary system could reveal conditions suitable for life.

Sono 7 pianeti che orbitano intorno ad una stella rossa.
Le temperature potrebbero rendere possibile la presenza di acqua allo stato liquido e quindi della vita, in condizioni non dissimili dalla terra.
A "solo" circa 40 anni luce dal nostro sistema.
