And seven of these far-off stars are known to have their own orbiting exoplanets that might support life. “And I was like, ‘No, there’s a finite clock backtrack you can do,’” Faherty explains. From the Gaia data set, Faherty and Kaltenegger picked out the stars within about 300 light-years of our sun—those “in our neighborhood,” Faherty says. Four are at the right distance from TRAPPIST-1 to conceivably support life, Kaltenegger says. Faherty says that beyond orienting searches for extraterrestrial life, she hopes this new star map inspires and opens minds.
