Scientists have found the oldest direct evidence for tectonic motion on Earth by more than half a billion years ...

Earth is believed to have formed partly from carbonaceous meteorites, which are thought to come from outer main-belt asteroids. Telescopic observations of outer main-belt asteroids suggest that they ...

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 journey through the Milky Way might have helped create the planet’s first continents. Comets may have bombarded Earth every time the early solar system traveled through our galaxy’s spiral ...

The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals ...
