The Morning Glory cloud is a rare meteorological phenomenon consisting of a low-level atmospheric solitary wave and associated cloud, occasionally observed in different locations around the world. The wave often occurs as an amplitude -ordered series of waves forming bands of roll clouds .
A woman in Calgary, Alberta, Canada, saw a strange, wavy cloud in the sky on Feb. 22, 2025, and took to X, formerly known as Twitter, to crowdsource an answer.
NASA’s Curiosity Mars rover captured these drifting noctilucent, or twilight, clouds in a 16-minute recording on Jan. 17, 2025. The white plumes falling out of the clouds are carbon dioxide ice ...
The Kordylewski clouds are located near the L 4 and L 5 Lagrange points of the Earth–Moon system. They are about 6 degrees in angular diameter. [7] The clouds can drift up to 6 to 10 degrees from those points. [11] Other observations suggest they move around the Lagrange points in ellipses of about 6 by 2 degrees. [7]
Noctilucent clouds form mostly near the polar regions, [7] because the mesosphere is coldest there. [15] Clouds in the southern hemisphere are about 1 km (3,300 ft) higher than those in the northern hemisphere. [7] Ultraviolet radiation from the Sun breaks water molecules apart, reducing the amount of water available to form noctilucent clouds.
The rare and mesmerizing formation featured in Hunter's photo is actually known as a Kelvin-Helmholtz cloud, a name derived from Lord Kelvin and Hermann von Helmholtz, the two scientists who ...
Representation of upper-atmospheric lightning and electrical-discharge phenomena Discovery image of a TLE on Jupiter by the NASA Juno probe. [1]Upper-atmospheric lightning and ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
