Speeding around the Earth at 28,000 km/h, NASA astronaut Nichole Ayers captured an incredible view of a phenomenon known as a red sprite. Here's the science behind this 'transient luminous event'.

Lightning, which can heat the atmosphere to five times the temperature of the surface of the sun, is the result of a powerful ...

A new experiment looking at clouds is about to change the way we think about climate change. For decades, scientists have thought that the tiny particles that form clouds — and play a big role ...

Astronomers have found 11 unexpectedly cold hydrogen clouds hiding in the superheated turbulence of the Fermi Bubbles, in a discovery likened to finding ice cubes inside a volcano.

And like on Earth, lightning often is generated within these clouds — an eerie sight spotted by various spacecraft, including Juno, that have visited our solar system's largest planet.

The formation of a sprite starts inside a thunderstorm. There, the exchange of electrons between colliding ice crystals and snow pellets produces distinct regions of electric charge within the cloud.
