NASA's planet-hunting TESS mission has found its first Earth-size exoplanet in a star system only 53 light-years from Earth
NASA's planet-hunting TESS mission has found its first Earth-size exoplanet in a star system only 53 light-years from Earth. Another exoplanet, a warm mini-Neptune, was found in the same system.
"It's so exciting that TESS, which launched just about a year ago, is already a game-changer in the planet-hunting business," Johanna Teske, author of a study describing the planets and Hubble Postdoctoral Fellow at the Carnegie Institution for Science, said in a statement."The spacecraft surveys the sky and we collaborate with the TESS follow-up community to flag potentially interesting targets for additional observations using ground-based telescopes and instruments.
