How Superstorm Gannon Squeezed Earth’s Plasmasphere To One-fifth Its Size
A geomagnetic superstorm is an extreme space weather event that occurs when the Sun releases massive amounts of energy and charged particles toward Earth. These storms are rare, occurring about […]

Interstellar Comet 3I/ATLAS: Evidence for Galactic Cosmic Ray Processing
Spectral observations of 3I/ATLAS (C/2025 N1) with JWST/NIRSpec and SPHEREx reveal an extreme CO2 enrichment (CO2/H2O = 7.6+-0.3) that is 4.5 sigma above solar system comet trends and among the […]

Coronal Mass Ejections At The Dawn Of The Solar System
Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs).

Exploring Stellar Activity In A Sample Of Active M Dwarfs
Most M dwarfs show higher chromospheric activity, often exceeding solar levels. Characterizing stellar activity is essential, particularly since these stars are prime targets in the search for habitable exoplanets.
