An Impact Basin Thermometer for the Moon

by Laurent G. J. Montési 22 April 202216 June 2022

Large impact basins on the near side of the Moon lack the annulus of thickened crust that far-side basins have. The difference can be linked to the thermal structure of the lunar crust.

When Less is More—The Moon Sheds Light on Clouds at Night

by Jonathan H. Jiang 12 April 20227 February 2024

Shining light into the dark reveals the unseen, but in some cases, it changes our perception of reality. Through moonlight we learn how the environment tricks our ways of finding nocturnal clouds.

A rocky planet and a smaller rocky moon sit on a black background with dark red streaks. The planet in the foreground has a cratered surface and has patches of red, green, gray, and blue rocks. The smaller grayish brown rocky moon in the background is between 10 and 11 o’clock relative to the planet.
