Space & Planets

A hemispherical panorama of the Moon’s surface with a black background. The Moon’s surface is rough textured and light gray speckled with darker gray splotches. One of the Chang’e-5 lander’s feet rests in the center of the image. It has a black circular foot and is supported by a tripod wrapped in gold foil. The flat bottom edge of the hemisphere is taken up by a blurred view of the lander’s body. A white sampling arm extends from near center to the 1 o’clock position on the hemisphere.

Planetary Dunes Tell of Otherworldly Winds

by Timothy Titus, Serina Diniega, Lori K. Fenton, Lynn Neakrase and James Zimbelman 22 December 202116 February 2022

On Earth and throughout our solar system, ripples and dunes in sand and dust offer insights into how winds blow, liquid currents flow, and solid particles fly and bounce over the terrain.

The light green planet Uranus sits on a black background. One bright white and many faint white concentric rings encircle the planet face on, and many small white specks, its moons, are scattered across the image.
