Astronomers offer a new bucket list for other worlds
http://phys.org/news/2016-08-astronomers-bucket-worlds.html
Lisa Kaltenegger, professor of astronomy and director of Cornell's Carl Sagan Institute, lead author Stephen Kane of San Francisco State University
and other scientists have written "A Catalog of Kepler Habitable Zone Exoplanet Candidates," which will be published in a forthcoming Astrophysical
Journal – listing more than two dozen possibly perfectly placed planets with potential to have liquid water or even life.
Nearly 3,500 exoplanets have been found by NASA's Kepler mission – launched seven years ago to survey the Milky Way.
"We're trying to make interstellar travel just a little bit easier," Kaltenegger quipped. "These exoplanets are the first ones we'd like to examine –
with more to come – as every day we're finding more. These are the first few pages in our ever-expanding travel guide."
