The Pale Red Dot campaign that discovered Proxima Centauri b produced one of the great results of exoplanet detection. For many of us, the idea that a world of roughly Earth mass might be orbiting in Proxima Centauri’s habitable zone — where liquid water can exist on the surface — was almost too good to be true, and it highlighted the real prospect that if we find such a planet around the closest star to our own, there must be many more around similar stars. Hence the importance of learning more about our closest neighbors.
Which is why it’s so heartening to see that Pale Red Dot is by no means done. This morning, the team led by Guillem Anglada-Escudé (Queen Mary University, London) announced plans to acquire data from the European Southern Observatory’s HARPS instrument (High Accuracy Radial velocity Planet Searcher) in a new campaign to study not just Proxima Centauri in search of further planets, but also the red dwarfs Barnard’s Star and Ross 154.

Also involved will be a network of small telescopes performing photometric monitoring, including the Las Cumbres Global Observatory Telescope network, SpaceObs ASH2 in Chile, the Observatorio de Sierra Nevada and the Observatorio Astronómico ...
