Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

How can the metal content of stars influence the formation of Earth-like exoplanets? This is what a recent study published in The Astronomical Journal hopes to address as an international team of ...

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.

Violent collisions between the growing Earth and other objects in the solar system generated significant amounts of iron vapor, according to a new study by LLNL scientist Richard Kraus and colleagues.
