Three of them are in what is described as the "habitable zone" where scientists say liquid water... and therefore life... could possibly exist.
Thomas Zurbuchen, NASA's associate administrator for the Science Mission Directorate, made the announcement and says "finding a second earth is not just a matter of if, but when"
Natalie Batalha, an astrophysicist at NASA and the project scientist for NASA's Kepler Mission, spoke to Morning Report shortly after the announcement and says the star Trappist 1 is one of the very closest systems to harbor earth sized habitable worlds
