NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered another Earth-sized, potentially habitable planet orbiting around a star in the range of distances where conditions could allow for the presence of liquid water on the planet’s surface.
“TESS was designed and launched specifically to find Earth-sized planets orbiting nearby stars,” said Paul Hertz, astrophysics division director at NASA Headquarters in Washington, in a statement. “Planets around nearby stars are easiest to follow-up with larger telescopes in space and on Earth. Discovering TOI 700 d is a key science finding for TESS. Confirming the planet’s size and habitable zone status with Spitzer is another win for Spitzer as it approaches the end of science operations this January”.
