NASA's TESS Telescope Just Discovered 1st Alien World A 'Super-Earth'


The Transiting Exoplanet Survey Satellite (TESS), NASA's most up to date planet-seeker, simply hit another milestone, has announced has identified its first outsider world — a "Super-Earth". 

An exoplanet about double the extent of Earth has been discovered circling a star called Pi Mensae around 60 light years away.

“This is one of the first objects we looked at,” says Chelsea Huang, a TESS scientist at the Massachusetts Institute of Technology. “We were immediately saying ‘hey this is too good to be true!’”

NASA launched the Transiting Exoplanet Survey Satellite (TESS) on April 18, 2018, and it started activities on July 25. In an early trial of its powers, the satellite seized its first light picture on August 7, which we at last got the chance to see this past Monday. 

The outsideworld, Pi Mensae c, takes 6.27 days to finish a circle around its parent star, Pi Mensae. That star is so splendid, it's unmistakable to the naked eye from a dim sky site on the southern side of the equator. It was beforehand found to have a planet the mass oftenJupiters revolving around it.

TESS works by watching a large number of close-by stars in the Milky Way, searching for indications of planets traveling them miniscule plunges in the stars' brilliance can give away the nearness of a circling planet immediately going before them. Such a blip in the light from Pi Mensae was distinguished in the principal month of perceptions channeled home by TESS, says Huang. 

The researchers detailed their discoveries online Sept. 16 out of a paper submitted to The Astrophysical Journal Letters. You can read it at the online preprint site arXiv.org.
