We stare at clouds all the time, whether trying to figure out what they look like or if they're bringing rain. Yet most of us ...

Cirrus clouds don't just form and die, but can regenerate, detailed images of ice crystals show. The pictures are some of the first results to come out of the Tropical Warm Pool International ...

What's that in the sky? In this week's Science Snippet, Meteorologist Stefanie Lauber explains the science behind these cool ...

Ice crystals floating in a high, thin layer of cirrostratus may allow blue sky and nighttime stars to shine through with minimal obstruction. A cumulonimbus cloud thick with water droplets, though ...

In the summer, the same effect can be achieved by thin cirrus clouds at 20,000 to 30,000 feet, where the air is cold enough that the clouds are made of ice.

The only types of clouds that can form moon dogs are again cirrus and cirrostratus clouds. However, low-level ice crystals suspended in the air can form moon dogs also.

Cirrus clouds don't just form and die, but can regenerate, detailed images of ice crystals show. The pictures are some of the first results to come out of the Tropical Warm Pool International ...

Light passes through some clouds more easily than others, depending on their composition and the thickness of the cloud layer. It’s much easier to see celestial events through thinner layers of clouds ...
