Uranus appears beyond the horizon of its moon Miranda in this illustration. If detectable, high-energy neutral particles produced near Uranus could help scientists decipher the structure and dynamics of the icy planet’s magnetosphere. Credit: NASA’s Goddard Space Flight Center Conceptual Image Lab

Most climate models set the concentration of methane for long-term simulations. Example concentrations are shown for two seasons: (a) December, January, and February and (b) June, July, and August. This study instead drives the simulations with regionally varying emissions, which leads to sharper gradients in atmospheric concentrations of methane for (c) December, January, and February, and (d) J…

Some studies show that particles from tire wear account for nearly half of the microplastics in terrestrial and aquatic systems. A new study examines how this debris affects marine life. Credit: Taylor McBride/Flickr , CC BY-NC 2.0

Map of the Aleutian Arc in Alaska and the Andreanof study area. The lower map shows where ocean-bottom seismometers and land seismic stations recorded sound waves from an active-source seismic experiment conducted aboard the R/V Marcus G. Langseth , allowing the authors to image the deep structure of the arc crust beneath several Aleutian volcanoes. The black lines show the Langseth ship track an…

A comparison of modeled and observed soil organic carbon (SOC) stocks for three commonly used soil biogeochemistry models (a-c). Each panel reports model performance metrics generated with “default” model parameters and with parameters informed by observations (“fitted”). While model performance tends to increase with fitted parameters, all three models poorly predicted SOC stocks in Sub-Saharan …

An artistic representation of WASP-94A b, a gas giant in the Microscopium constellation, shows how clouds build on the dark side of the planet and are blown to the dayside, where they dissipate. This leaves the morning edge of the planet, where the winds move from nightside to dayside, permanently overcast. Credit: Hannah Robbins/Johns Hopkins University

Only a handful of spacecraft, some of which are illustrated here, monitor the vast space between the Sun and Earth, including the planet’s magnetosphere. To forecast space weather effectively, scientists must connect these scattered observations and extract as much information as possible from the limited data they provide. Credit: Mary Heinrichs/AGU
