clouds

What it's like to skydive through a cloud depends in part on the type of cloud, but regardless, you'll likely end up cold and wet.

The rays appear when sunlight shines through gaps in the cloud during sunrise or sunset and have never been seen this clearly on the Red Planet before.

Rare clouds that give off bright, multi-colored light like an aurora were recently spotted at multiple locations in the Arctic. But what causes them?

Clouds look light and fluffy, but they're surprisingly heavy.

A new time-lapse video shows an unusual banner cloud, known locally as "The Levanter," forming on the peak of the Rock of Gibraltar.

A satellite image captured by Landsat 8 shows Mount Vesuvius "peering" through an eerily circular hole in the clouds.

Satellite images released by NASA's Earth Observatory show concentric rings of clouds forming above the erupting volcano on La Palma in the Canary Islands.

Earth is reflecting less light as its climate continues to change, new research suggests.

A NASA-funded study is giving scientists insight into how "night-shining clouds" form in the upper atmosphere — and the role that growing space traffic plays in the phenomenon.
