Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

The habitability of the surface of any planet is determined by a complex evolution of its
interior, surface, and atmosphere. The electromagnetic and particle radiation of stars drive …

Abstract During its 2 yr Prime Mission, TESS observed over 232,000 stars at a 2 minute
cadence across∼ 70% of the sky. These data provide a record of photometric variability …

The 4.1-billion-year-old meteorite Allan Hills 84001 (ALH 84001) may preserve a magnetic
record of the extinct martian dynamo. However, previous paleomagnetic studies have …

Earth's magnetic field was in a highly unusual state when macroscopic animals of the
Ediacara Fauna diversified and thrived. Any connection between these events is tantalizing …

The paleomagnetic record is an archive of Earth's geophysical history, informing
reconstructions of ancient plate motions and probing the core via the geodynamo. We report …

This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its
composition by interior/exterior cycling. The formation and evolution of Venus's atmosphere …

Context. The James Webb Space Telescope is currently at the forefront of the search for
atmospheres of exoplanets. However, the observation of atmospheres of Earth-like planets …
