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 ...

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

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 ...

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 ...
