Earth

Cornell astronomers have created five models representing key points from our planet’s evolution, like chemical snapshots through Earth’s own geologic epochs.

A recent study is contributing to our understanding of the end-Cretaceous mass extinction, which occurred some 66 million years ago. This event is possibly best known for wiping out the dinosaurs, and is one of the most well-studied mass extinctions in Earth’s history.

By measuring iron isotopes, researchers from the University of Copenhagen have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.

Research suggests that sulfur in the oceans may not have played as large a role as expected in delaying the evolution of more complex life.

Research team explores how fundamental features of genome affects organism's ability to thrive in an extreme environment on Earth and beyond.

Is it possible that our notions of what makes a planet suitable for life are too limiting? Scientists are finding that the answer not only is yes, but that it’s yes under a range of surprising conditions compared to Earth.

For the 30th anniversary of one of the most iconic views from the Voyager mission, NASA's JPL is publishing a new version of the image known as the "Pale Blue Dot."

Some Scientists Believe Life Formed in Thermal Pools like Those in Yellowstone National Park

New evidence has confirmed Australia’s Yarrabubba crater as the world’s oldest preserved impact structure - but did it thaw Earth and end an ice age?

Earth’s breathable atmosphere is key for life, and a new study suggests that the first burst of oxygen was added by a spate of volcanic eruptions brought about by tectonics.
