Nudging Earth’s Ionosphere Helps Us Learn More About It

Sarah Stanley, Science Writer by Sarah Stanley 17 June 202517 June 2025

New observations and simulations capture the physics at play across each of the three main ionospheric regions.

Four seemingly identical, octagonal, disklike structures, each with several various thin antennas extending outward at various angles, appear to be floating in a closely spaced cluster in space. In the background, on the right side of the image, is the round shape of the planet Earth, encircled by translucent, overlapping blue and purple lines.

The Deep Frontier of Mantle Magma Supply

by Ben Black, Samer Naif, Forrest Horton, Andrea Goltz and Cian Wilson 25 March 202525 March 2025

Compared with crustal magma systems, little is known about the deep sources of volcanic supply chains. Interdisciplinary efforts can help answer key questions about how magma migrates from the mantle.

The Relatively Messy Problem with Lunar Clocks

by Matthew R. Francis 14 November 202414 November 2024

Using Einstein’s theory of general relativity, physicists found that clocks on the Moon would run 56 microseconds faster than clocks on Earth. That finding will help future lunar missions navigate.
