An international team of astronomers, led by Guillem Anglada-Escude from Queen Mary University, reports two new planets orbiting a very old and nearby star to the Sun named Kapteyn's star. One of the newly-discovered planets, Kapteyn b, is potentially habitable as it has the right-size and orbit to support liquid water on its surface. What makes this discovery highly interesting is the peculiar story and age of the star. Kapteyn b is likely over twice the age of Earth and the oldest known potentially habitable planet listed in the Habitable Exoplanets Catalog.



What struck me the most is the fact there is now such thing as Habitable Exoplanets Catalog



Check out the link at the end of the article to a short short by Alastair Reynolds; I am pretty sure this is the shortest amount of time between discovery of an exoplanet, and it turning up in a SF story
