Scientists have long been intrigued by the surfaces of terrestrial bodies other than Earth that reveal deep similarities beneath their superficially differing volcanic and tectonic histories. A team ...

To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in ...

NASA's James Webb Space Telescope has scored another first, detecting evidence of water in a planet-forming disc circling another star where at least two terrestrial-class proto-planets seem to be ...

Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

How do terrestrial planets like Earth form and evolve to enable life to exist? This is what a recent study published in Nature hopes to address as a pair of scientists from the Southwest Research ...

Artistic concept of the PDS 70 disk. JWST observations detected water in the inner disk, where normally terrestrial planets form. Two gas giant planets carved a wide gap in the disk made of gas and ...

Astronomers at MIT, Harvard University, and elsewhere have searched a rocky, Earth-sized exoplanet for signs of an atmosphere—and found none.

A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment. A terrestrial planet ...
