Trappist SETI

With the discovery of 7 Earth-sized planets in the Trappist-1 system, including 3 in the star's habitable zone, SETI researchers will likely listen to the system.

The discovery also suggests dwarf stars, the most common stars in the universe, should be fully in play in the search for life.

Trappist-1 is an ultracool dwarf star only slightly bigger than Jupiter.  It is the most common type star in the universe.  Orbiting it are seven Earth-sized worlds-- three of which orbit in the star's habitable zone.

Trappist-1 is only 39 light years away, so the next generation of large telescope will be able to study the worlds' atmospheres in detail, in a search for life.
