Astronomers Confirm Existence Of Earth-like Planet That Orbits The Nearest Star From The Sun

An international team of astronomers have made observations that confirm that our nearest star neighbour, Proxima Centauri does host Proxima b, an Earth-like planet in its habitable zone.By&nbsp;May 29, 2020&gt;ScienceAn international team of astronomers have made observations that confirm that our nearest star neighbour, Proxima Centauri does host Proxima b, an Earth-like planet in its habitable zone.Located about 4.2 light-years from our Sun in the constellation Centaurus, Proxima Centauri is the closest star to the Solar System. Back in 2013, astronomers had first detected the presence of a planet around the red dwarf star. Later on, in 2016, astronomers made radial velocity measurements using ESO’s HARPS instrument on the 3.6-metre telescope at La Silla, Chile. They a lot about the orbital path of the potential exoplanet Proxima b and estimated that it was 1.3 times the mass of Earth.Now in a that has been accepted to be published in Astronomy &amp; Astrophysics, astronomers have confirmed that the exoplanet does exist. The discovery was made with new radial velocity observations from the ESPRESSO on ESO’s Very Large Telescope in Chile. The new observations were about three times more precise than those obtained with HARPS.The lead author of the new study, Alejandro Suarez Mascareño said in a that by “Confirming the existence of Proxima b was an important task, and it’s one of the most interesting planets known in the solar neighbourhood.”Researchers from , have confirmed the existence of the using measurements from the Swiss-built spectrograph.— UNIGE_en (@unige_en)SEE ALSO:Astronomers found that Proxima b has a mass of about 1.17 times that of the Earth. They confirmed that the Earth-like exoplanet orbits its host star in just 11.2 days, as previously predicted. The orbital path is about 20 times closer to Proxima Centauri than the Earth is to the Sun. But as Proxima Centauri is a red dwarf star, it receives energy that is enough to maintain temperatures that can host water in liquid form.While Proxima b is within the habitable zone of Proxima Centauri, scientists are not suggesting that life can develop on the planet as it is being bombarded with 400 times more X rays than the Earth. Christophe Lovis, a researcher in UNIGE’s Astronomy Department and part of the ESPRESSO team that sustainability of life would depend on the protection provided by its atmosphere “And if this atmosphere exists, does it contain the chemical elements that promote the development of life (oxygen, for example)? How long have these favourable conditions existed? ”Researchers explain that further observations by other instruments like RISTRETTO and HIRES would be able to help with such questions. Additionally, researchers in their study also found evidence of a second signal in the data, apart from Proxima b which could be of planetary origin.The principal Investigator of ESPRESSO, Prof Francesco Pepe from the Astronomy Department in UNIGE’s Faculty of Science , “If the signal was planetary in origin, this potential other planet accompanying Proxima b would have a mass less than one-third of the mass of the Earth. It would then be the smallest planet ever measured using the radial velocity method.”SEE ALSO:Image Source:: , , , , , , ,
