‘Nature’s 10’, the annual list which distinguishes the year’s best scientists according to the journal, has included Catalan astronomer, Guillem Anglada-Escudé amongst its names. The researcher at Queen Mary University of London detected the nearest known planet outside the Solar System which he baptised ‘Proxima b’. He put together a team and got observing time on the High Accuracy Radial velocity Planet Searcher (HARPS) at the European Southern Observatory as well as other telescopes that could double-check whether any promising evidence that they found was caused by stellar activity, which can mimic the signs of a planet. Within days, they confirmed that the planet was there; within weeks, they submitted a manuscript detailing their discovery. The planet, called Proxima b, has at least 1.3 times the mass of Earth and orbits Proxima every 11.2 days.
