This is caused by the gravitational influence of planets that orbit the star, the extent of which is used to infer the mass of the planets. This method consists of observing the spectra of stars for signs of "wobble," where the star is moving closer and farther away from Earth. Using the High Accuracy Radial velocity Planet Searcher (HARPS) spectrograph on the ESO 3.6-meter telescope at the ESO's La Silla Observatory, the team confirmed the presence of Proxima b using a method known as Doppler spectroscopy (aka. The people responsible for the discovery were Guillem Anglada-Escudé and a team of astronomers from the Pale Red Dot campaign. She was joined by researchers from The Adler Planetarium, the Center for Space Science and Technology (University of Maryland), and the Exoplanets and Stellar Astrophysics Laboratory at the NASA Goddard Space Flight Center. Gilbert, a Graduate Student with the University of Chicago's Department of Astronomy and Astrophysics. The study that describes their findings, which will appear soon in Frontiers in Astronomy and Space Sciences, was led by Emily A. But in a new NASA-supported study, a team led by astrophysicists at the University of Chicago determined that this is an unlikely possibility. All of these studies indicate that this question cannot be answered until astronomers characterize Proxima b's atmosphere, ideally by observing it as it passes in front of (i.e., transits) its host star.
Unfortunately, the scientific community has been divided on whether or not life could even be possible on this planet.
