How any Earth-sized exoplanets exist, and how do we find them? This is what a recent study published in The Astrophysical ...

Although astronomers have directly imaged a few dozen gas giants on the scale of Jupiter, Earth-sized planets are too small and dim to be directly imaged. That's not to say there's a shortage of Earth ...

Learn about HD 137010 b, a cold Earth‑sized planet candidate that sits near the outer edge of its star’s habitable zone.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting ...

A NASA mission has spotted an Earth-size exoplanet orbiting a small star about 100 light-years away. The planet, named TOI 700 e, is likely rocky and 95% the size of our world. The celestial body is ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

Computer simulations suggest NASA’s Habitable Worlds Observatory could detect Earth-like exomoons around gas giant exoplanets through reflected starlight and lunar eclipses.

Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life? The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...
