NASA introduced Wednesday that its Transiting Exoplanet Survey Satellite (TESS) has uncovered a probably livable planet just 31 light-years far from our solar system.
Transiting Exoplanet Survey Satellite member and associate professor of astronomy Lisa Kaltenegger, who led the international group and who is also director of Cornell’s Carl Sagan Institute, mentioned in an announcement the invention of the exoplanet, named GJ 357 d, “is humanity’s first nearby super-Earth that would harbor life.”
Astronomers from the University of La Laguna, Spain and the Institute of Astrophysics of the Canary Islands, revealed the findings on the GJ 357 system within the journal Astronomy & Astrophysics, and they have been presented at an exoplanet convention in Cambridge, Massachusetts.
The astronomers detected via Transiting Exoplanet Survey Satellite another planet orbiting the identical star, named GJ 357, and deeper analysis by Spanish astronomers led to the discovery of 2 more planets within the system — together with the super-Earth, GJ 357 d, which takes nearly 56 days to orbit its host star at a distance approximately one-fifth of that between Earth and the sun.
The other 2 recognized planets within the star system, GJ 357 c, and GJ 357 b, are believed to be far more hot to be habitable, based on Kaltenegger.
Kaltenegger mentioned a pair of next-generation telescopes in Chile should reveal more particulars once operating in 2025 in regards to the super-Earth, together with whether or not it’s rocky or has oceans.
