Take a look at the sky on any given day and you’ll likely see clouds of different shapes — some look like cotton balls, ...

When volcanic eruptions send towering plumes of ash into the atmosphere, they don’t just darken the sky or affect local air ...

Satellites soaring high above Earth have revealed exactly how wispy clouds are created by the giant plumes of ash belched ...

Volcanic ash from eruptions can reshape cirrus clouds, forming giant ice crystals and altering how Earth traps heat in the ...

“We anticipated that volcanic aerosols would lead to an increase in the number of ice crystals in clouds. But to our surprise, the data showed the opposite.” Dealing with Cirrus Clouds The team ...

sun halos form when high-altitude clouds — specifically cirrus or cirrostratus clouds — contain ice crystals that act like tiny prisms. These ice crystals refract and bend sunlight ...

Lunar halos are caused by thin, wispy, cirrus and cirrostratus clouds and refraction and reflection of moonlight by the clouds' ice crystals. Below, we explore the lunar spectacle of a ring around ...

Halos form around the sun or the moon whenever their light passes through ice crystals in high-level cirrus clouds. These crystals act like a prism, bending that light at an angle of 22° angle ...

According to the National Weather Service, a halo results from light refracting off ice crystals present in a thin layer of cirrus clouds. Halos often appear white, but can show colors as well.

The spherical ice crystals that make up the clouds are ... and they look similar to cirrus clouds, a type of wispy, hair-like cloud that forms at high altitudes, according to the U.K. Met Office.

These halos are caused by high cirrus clouds positioned approximately 20,000 feet above the ground that contain tiny ice crystals. The halos result from the refraction and reflection of light by ...
