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 ...

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.

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

New simulations suggest that up to four of the solar system's rocky planets, including Earth and a long-lost world, once orbited in mathematical harmony around the infant sun. When you purchase ...

Jupiter is old. Like 4.5 billion years old. It started as a swirling disk of gas and dust that formed into a pretty big ...
