There are so many exoplanets being discovered, and so many that lie in the the range of what we consider habitable.
Stories about potentially Earth-like planets orbiting far away stars have been making the headlines for years. With the Kepler spacecraft monitoring the stars, searching for telltale dips in brightness that indicate the presence of a planet, and a host of telescopes adding their capabilities to the mix, discoveries have been coming in at an amazing pace. But with each new potential Earth 2.0, the excitement is a little less, especially considering that even the closest discovery is so far away that each represents little more than a curiosity – until now.
Using two instruments mounted on telescopes in Chile – the Ultraviolet and Visual Echelle Spectrograph (UVES) and the High Accuracy Radial velocity Planet Searcher (HARPS) – astronomers detected a slight wobble in the red dwarf star, Proxima Centauri, which indicates the presence of a planet. After focusing HARPS on the star for months in early 2016, and combining it with data…
