Image of the “Peachflya” abrasion spot, from Perseverance’s WATSON Camera on sol 1620. NASA/JPL-Caltech larger image Perseverance accomplished something unusual this week: abrading two dramatically different rocks within the span

Figure adapted from M. MacLeod et al. (2025) and compiled using PWMorphology. Colored circles represent confirmed exoplanets with radii greater than 1.6R⊕ from the sunset catalog shown as a function

ALMA 1.5 mm continuum emission towards the G351.77−0.54 star-forming region. Crosses mark the positions of the mm continuum sources identified by H. Beuther et al. (2019). The synthesized beam of

Overview of the workflow and experimental design. a) Workflow exposure experiment: Cultivation, followed by cell enrichment and deposition in the exposure wells to conduct 1. desiccation experiment, and 2. exposure

JWST NIRSpec PRISM transmission spectra compared with modeled atmospheric scenarios. The x-axis shows wavelengths in microns, while the y-axis shows the transit depth in parts per million. Each of the

Ice sheet topography computed by GRISLI (step RGRGRG). For this particular simulation, the ice sheet reaches the ocean and could potentially produce icebergs. The altitude here includes the isostasy that

H2 abundance constraints for TRAPPIST-1 e from HST and JWST as a function of surface pressure. Posterior distribution showcasing the improvement on constraints on possible H2-dominated atmospheres on TRAPPIST-1 e
