Washington – Scientists have for the first time obtained measurements of upper atmosphere temperatures, iron densities, and mesospheric clouds over the North and South Poles. As reported in the April ...

Electric-blue clouds’ appearance farther south may be proof of climate change In a few weeks, you may get to see evidence the atmosphere is changing – if you’re lucky. That’s when noctilucent clouds, ...

An astronaut aboard the International Space Station took this oblique photograph of polar mesospheric clouds during one of the 16 sunsets visible from the station each day. Polar mesospheric clouds, ...

NASA’s AIM satellite has provided the first global-scale, full-season view of iridescent polar clouds that form 50 miles above Earth’s surface. The Aeronomy of Ice in the Mesosphere (AIM) mission is ...

Scientists have discovered why icy clouds found at the edge of space are higher at the South Pole than at the North. The answer to this puzzle is that the intensity of solar radiation at the South ...

ISS017-E-011632 (22 July 2008) — Polar Mesospheric Clouds (also known as noctilucent clouds) are transient, upper atmospheric phenomena observed usually in the summer months at high latitudes (greater ...

CHAMPAIGN, Ill. -- Polar clouds are known to play a major role in the destruction of Earth's protective ozone layer, creating the springtime "ozone hole" above Antarctica. Now, scientists have found ...

Each year, a glowing mass of clouds forms over the South Pole, high in the atmosphere, trapped between Earth and space. From the ground they look wispy and shimmery, like a blue-white aurora borealis.

Polar mesospheric clouds, commonly known as noctilucent clouds, represent a delicate yet telling phenomenon occurring near the mesopause at altitudes around 80 km. Their presence not only provides a ...

High above the familiar cotton wool of weather systems, a stranger kind of cloud is quietly rewriting what we think we know ...

Noctilucent clouds are the rarest clouds in the world, but experts say in recent years they've made a better showing, and skywatchers in the Pacific Northwest have been treated to spectacular displays ...

To investigate how these glowing clouds form, Richard Collins a space physicist, and his team in 2018 launched a suborbital rocket filled with water, known as NASA's Super Soaker Rocket, into the ...
