The Hermean Helium Exosphere—Continuous and Sporadic Helium Release Processes
Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract Since its detection by Mariner 10, helium has been a key focus in studies of Mercury's exosphere. Recently, Weichbold et al. (2025), https://doi.org/10.1029/2024je008679 provided the first in situ helium measurements, inferring density from Ion Cyclotron Wave (ICW) events observed by the MESSENGER spacecraft.

Review of asteroid, meteor, and meteorite‐type links
Meteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Shock‐heated graphite in three IAB iron meteorites—Implications on the formation of diamond
Meteoritics &Planetary Science, Volume 60, Issue 4, Page 744-756, April 2025.Abstract Iron meteorites, originating from the deepest parts of their parent bodies and separated during major break‐up events, surprisingly rarely contain diamonds despite experiencing similar pressure–temperature conditions as diamond‐bearing ureilites. In this study, graphite from three non‐magmatic IAB iron meteorites Canyon Diablo, Campo del Cielo,
