NASA's TESS spacecraft reports its first exoplanet
Thursday, September 20, 2018
In findings released to the public on Monday through online site National Aeronautics and Space Administration's (NASA's) (TESS) to locate an exoplanet. The planet, called , was spotted as it was transiting in front of its star, Pi Mensae (HD 39091). The paper describing the findings was being submitted to AAS Letter but had yet to be published in full., astronomers reported they have already used data from the first photograph taken by
"Here, we report on the discovery of a transiting planet around [Pi Mensae], exactly the type of planet TESS was designed to detect," states a portion of the paper available to the public.
Scientists say the planet is roughly twice the diameter of Earth but about four times as massive. Findings for Pi Mensae c indicate it may contain helium, methane, hydrogen, and water but is deemed unlikely to support life because it is so close to its star.
TESS, which launched last April, created the light image over the course of 30 minutes on August 7, using four optical telescopes to photograph a small portion of the night sky. Its mission is slated to last two years and reports anticipate it could discover thousands of exoplanets.
This week in an unrelated project, researchers from the Star Trek, this star system is the home of the like . The exoplanet, officially called HD 26965b, has been nicknamed "Vulcan" after this fictional planet.spotted a planet circling a star named (HD 26965). In the fictional universe of
