held in place by the Earth’s gravitational field. It’s made up of a mixture of different gases. About 78% of the atmosphere is nitrogen gas, N2, which is unreactive and just sort of hangs around.

For a long time, scientists believed that early life on Earth struggled due to a lack of usable nitrogen. This new discovery ...
