A New Hope

  • David S. Stevenson


In the last decade two new planetary systems have emerged from radial velocity data, those of Proxima Centauri and TRAPPIST-1. Proxima is a 0.12 solar mass red dwarf and the closest star to our Sun, making it a particularly attractive target for further investigation. Meanwhile, the older TRAPPIST-1 system has seven planets, several of which could be habitable—at least in the crudest sense. Although each system has its detractors and flaws, both could host sophisticated life and are easily the best systems we know of that could be habitable.
