The Space Weather Around Young Suns (SWAYS) program was introduced in Davis2025 as a multi-wavelength monitoring program for studying the activity and particle environments of nearby, young, solar-type stars.
Data beamed back from Mars by the NASA spacecraft MAVEN provides the first evidence that a phenomenon protecting planets from solar winds can occur in the atmospheres of worlds that […]
Young solar-like stars are efficient generators of magnetic activity, superflares, coronal mass ejections (CMEs), and stellar energetic particles. These phenomena drive the early evolution of stars and shape the habitability […]
We present the most comprehensive near-ultraviolet (NUV: 2550-3255 Angstrom) activity record to date for the Alpha Centauri AB system, combining archival IUE and HST observations spanning nearly five decades with […]
(Abridged) We search for evidence of star-planet magnetic interactions in the nearby Proxima Centauri planetary system using high-quality, high-spectral-resolution optical observations.
Astrometric monitoring of stars provides a promising method for discovery of low-mass planets around nearby Sun-like stars.
In December 2023, scientists looking at Mars data stumbled across something completely unexpected — observations of an atmospheric effect never before seen in the Red Planet’s atmosphere.
Ross 318 is an M3.5V red dwarf exhibiting significant magnetic activity and a stellar rotation period of ∼ 51.5 d.
![The H2 and [Ne II] emission detected towards DoAr 25 on top of the ALMA 240 GHz continuum emission (shown in the background as a reddish-yellow image). The white central circle shows the inner working angle from JWST. In this case, the disk itself is seen in absorption against line emission from the Ophiuchus PDR for H2 S(1)-S(3) (17.03-9.66 µm). -- astro-ph.SR)](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/05/Characterizing-The-Extended.png?resize=1200%2C721&ssl=1)
We present a comprehensive analysis of extended H2 emission from 34 protoplanetary disks observed with the JWST Disk Infrared Spectroscopic Chemistry Survey (JDISCS), supplemented by archival data.
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets’ high-energy irradiation environments, with consequences for atmospheric chemistry and escape, and they can contaminate transmission spectroscopy […]
