Late-stage planetary collisions reshaped Earth and its neighboring planets, delivering water, altering their atmospheres, and ...

Mercury is tiny, barely bigger than the Moon. Its metallic core makes up 70% of the planet’s mass, vastly exceeding Earth’s ...

Lava planets, which have one face perpetually turned toward their star and heated to temperatures capable of melting rock, offer a unique natural laboratory for exploring the interactions ...

Astronomers using the James Webb Space Telescope are unraveling the mysteries of TRAPPIST-1e, an Earth-sized exoplanet 40 ...

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 ...

A new SwRI-led paper highlights the scientific progress made in understanding the evolution of terrestrial planets, including the effects of late large impacts on pre-existing modes of tectonics. For ...

Fast-moving objects like interstellar comet 3I/ATLAS may be planet-forming seeds, potentially helping to solve an old Solar ...

New work from Carnegie’s Alan Boss offers a potential solution to a longstanding problem in the prevailing theory of how rocky planets formed in our own solar system, as well as in others. The snag he ...

Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers’ best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the ...

A new study published in the journal Proceedings of the National Academy of Sciences offers an intriguing explanation — and ...
