JWST Reveals Spectral Tracers of Recent Surface Modification on Europa - Astrobiology
Europa has been modified by a variety of geologic processes, exposing internally-derived materials that are heavily irradiated by charged particles trapped in Jupiter's magnetosphere.

Titan Could Harbor Life, But Only A Tiny Amount, Study Finds - Astrobiology
Titan, Saturn’s largest moon, is a strange, alien world. Covered in rivers and lakes of liquid methane, icy boulders and dunes of soot-like “sand,” its topography has long fascinated scientists and in...

NASA's Juno mission has identified an unprecedented volcanic hot spot on Jupiter's moon Io, surpassing previous records and offering new insights into extraterrestrial volcanism.
Juno mission spots most powerful volcanic activity on Io to date
Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme.

Seismic wave analysis reveals large, persistent magma bodies beneath dormant volcanoes in the Cascade Range, challenging previous assumptions about volcanic activity and eruption prediction. doi.org/g83fz4
Large magma bodies found beneath dormant volcanoes, surprising scientists
New Cornell University led-research challenges the long-standing belief that active volcanoes have large magma bodies that are expelled during eruptions and then dissipate over time as the volcanoes become dormant.

Recent findings indicate the Moon's geological activity may be more recent and dynamic than previously thought, with small ridges on its far side suggesting tectonic activity within the last 160 million years. doi.org/g83gzq
Moon is not as 'geologically dead' as previously thought, new study reveals
Scientists have studied the moon's surface for decades to help piece together its complex geological and evolutionary history.

Analysis of asteroid Bennu's dust reveals minerals formed by evaporating brine and precursors to biomolecules, suggesting the solar system's potential for life was more widespread than previously thought. doi.org/g83j3z
Dust from asteroid Bennu suggests solar system's potential for life was widespread
It took two years for NASA's OSIRIS-REx space probe to return from asteroid Bennu before dropping off a small capsule as it flew past Earth, which was then recovered in the desert of the U.S. state of Utah on September 24, 2023.
