Explore how Earth would appear without life. Studies from Universe Today and Cornell University reveal atmospheric signals, surface conditions, and implications for exoplanet observations.

Here's a thought experiment that keeps planetary scientists awake at night. Strip every living thing from our planet, every bacterium, every blade of grass, every creature that has ever drawn breath ...

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior.

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

Scientists have discovered that the evolution of land plants caused a sudden shift in the composition of Earth's continents. Scientists at the University of Southampton have discovered that the ...

What is the chemical composition of the Earth's interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth's deep interior ...

Scientists at the University of Southampton have discovered that the evolution of land plants caused a sudden shift in the composition of Earth’s continents. The Southampton researchers, led by Dr Tom ...
