Video Clip SS272144 (Phases of the Far Side of the Moon)

Animation showing a time-lapse wide-angle view of the phases of the far side of the Moon, with the Earth rotating behind it. 

The Earth rotates on its own axis in 24 hours. The Moon orbits the spinning Earth in approximately 27.3 days, but because the Moon rotates upon its own axis once during the same period, it always presents the same side to the Earth.

As the Moon orbits the Earth, the area of its surface lit by the Sun changes, resulting in the lunar phases. The animation was created using data from NASA’s Lunar Reconnaissance Orbiter.

Video Clip SS270763 (Kelvin-Helmholtz Wave Clouds, Timelapse)

Time-lapse footage of strong wind shears curling high-altitude clouds into a distinctive and ephemeral Kelvin-Helmholtz wave pattern. 

This distinct corkscrew pattern is formed by layers of air moving across each other in opposite directions, creating a series of circular air movements in between them. 

This type of cloud generally forms at high altitude and dissipates rapidly. The formation seen here is associated with a jet stream in the lee of the Rocky Mountains. 

Filmed on a winter’s afternoon in Colorado, USA.
