Earth-sized Planets

Astronomers discovered the first exoplanet around a Sun-like star in 1995. The field of exoplanet discovery and research has been rapidly evolving ever since.

LHS 475 b's size as an Earth-sized terrestrial planet was confirmed by JWST, however the exoplanet's atmosphere has not yet been determined.

The scientists used NASA's Transiting Exoplanet Survey Satellite and have identified an Earth-size world, called TOI 700 e.

The American space agency NASA is using the James Webb Space Telescope to find out more about potentially habitable planets.

University of Warsaw researchers have announced that they have detected a terrestrial-mass rogue planet. They used a technique called microlensing which allows them to find planets that they otherwise wouldn’t be able to. They call this event ‘the most extreme short-timescale microlens discovered to date.’

University of British Columbia (UBC) Astronomy Student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA's Kepler mission.

NASA's planet hunter satellite TESS has discovered an Earth-sized world within the habitable range of its star, which could allow the presence of liquid water.

NASA said Monday that its planet hunter satellite TESS had discovered an Earth-sized world within the habitable range of its star, which could allow the presence of liquid water.

NASA's new exoplanet hunter Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size world.

NASA is poised to launch a $337 million washing machine-sized spacecraft that aims to vastly expand mankind's search for planets beyond our solar system, particularly closer, Earth-sized ones that might harbor life.

If you were going to design a laboratory for answering questions about solar systems, you could hardly do better than TRAPPIST-1. The system, just 39 light-years away, comprises a dim red sun orbited by seven rocky, Earth-size worlds - almost as if someone had designed an experiment in planet formation.

One of our closest celestial neighbors is a warm, rocky world, scientists say. Writing in the journal Astronomy and Astrophysics, scientists report the discovery of an Earth-size exoplanet orbiting the star Ross 128, a dim red dwarf just 11 light-years away

Four Earth-sized planets have been discovered orbiting the nearest Sun-like star, which is about 12 light years away and visible to the naked eye, scientists said today.

A deep-space mission to discover habitable Earth-sized planets in other solar systems and detect extra-terrestrial life they may host has been given the go-ahead by the European Space Agency (ESA).
