Our solar system is a lot like the story of Goldilocks and the Three Bears. Planets that are located close to the sun can be too hot, while those located further from the sun can be too cold, making ...

— -- Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the "habitable" zone and make for a surface ...

Temperatures on the planet could make water theoretically possible. Astronomers are researching an Earth-like exoplanet that could contain water, according to NASA. The exoplanet, named TRAPPIST-1 e, ...

CAPE CANAVERAL, Fla. (AP) — Scientists revealed Wednesday that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...

A rocky planet similar to Earth may be orbiting one of our nearest stellar neighbors and could be detected using existing techniques, according to a new study led by astronomers at the University of ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

"At this point, we can rule out TRAPPIST-1d from a list of potential Earth twins or cousins." There's bad news for our hopes of habitable planets existing around TRAPPIST-1, with the James Webb Space ...
