In Earth’s early days, more than 4 billion years ago, the surface was a dangerous and unpredictable place. Violent volcanoes, crashing meteorites, and constant tectonic activity repeatedly resurfaced ...

Highly detailed fossils are typically found in shale or other fine-grained sedimentary rocks. These ones? They’re made of iron.

Squiggly markings like a punk rock hairdo led researchers to identify the remains as spongelike animals that may have lived around 560 million years ago.

Researchers from the Massachusetts Institute of Technology analysed chemical fossils from more than 541 million years ago.

The USGS publishes a geological map that reveals the underground layers of the U.S. and supports environmental education and ...

A pair of diamonds that formed hundreds of kilometers deep in Earth’s malleable mantle both contain specks of materials that form in completely opposing chemical environments—a combination so unusual ...

Coccolithophores, tiny planktonic architects of Earth’s climate, capture carbon, produce oxygen, and leave behind geological ...

Our planet had a "second moon" for a hot minute in 2024. This gave space entrepreneurs a bright idea. Almost a year ago, the space science community watched as an asteroid entered Earth's orbit and ...
