Perseverance Rover Snaps Selfie in Mars’ Western Frontier

The agency’s six-wheeled geologist took a self-portrait during its survey of an ancient landscape that may predate the formation of Jezero Crater itself.

Fatigue-crack Formation In Samples From Asteroid Bennu And Petrologic Controls On Boulder Properties And Evolution

Thermal fatigue has been observed to be an important driver of boulder evolution on asteroid Bennu through the development of morphological features such as exfoliation flakes and linear fractures in […]

Motional Induction in Ganymede’s Ocean

We investigate the magnetic signature of oceanic circulation in Ganymede’s subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field […]

A Public Dataset Of Ariel Simulated Observations For Developing Exoplanetary Atmosphere Data Reduction Pipelines

Detecting and characterising exoplanet atmospheres remains challenging because atmospheric signals can be comparable to residual noise and instrumental/astrophysical systematics. Spectral features span from a few ppm for small planets up […]

JWST Unveils A High Mean Molecular Weight Atmosphere For Mini-Neptune TOI-1130b: Evidence For Formation Beyond The Water Ice Line

We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R⊕, 19.8 M⊕, Teq∼825 K). It is part of a rare and unique […]
