Astronomers at Leiden University have detected rare isotopes of carbon and oxygen in our neighboring stars for the first time ...

When elements combine, they form compounds. For example, water is made of two atoms of the element hydrogen, and one atom of the element oxygen. That’s why it’s often denoted as H 2 O. A chemical ...

The work links a permanent oxygen boost in the Middle Devonian, roughly 393–382 million years ago, to the colonization of deeper waters by jawed fishes and other animals, a shift that lines up with a ...

Challenging Previous Views on Galaxy Evolution Oxygen is a crucial element on Earth, as it plays a crucial role in supporting ...

Ancient forests may have fueled a deep-sea oxygen boost nearly 390 million years ago, unlocking evolutionary opportunities ...

They report in their paper that this is likely due to a thermal pulse where a wave of high-pressure gas mixes layers of elements like carbon and oxygen and spews them out into the surrounding cloud.

Some 390 million years ago in the ancient ocean, marine animals began colonizing depths previously uninhabited. New research ...
