Crystals hidden in Australia’s oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests ...

Earth formed around 4.54 billion years ago. Knowing how old Earth is can be more difficult to confirm because Earth's age is not only based on the age of rocks, but also the isotopic estimates of what ...

A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. The Ohio State University study's results ...

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

New method reveals chemical signs of early microbial life in ancient Earth rocks, showing photosynthesis evolved much earlier ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

Helium-3, a rare isotope of helium gas, is leaking out of Earth’s core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a ...

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 ...

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group 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.
