A quantitative description and diagnosis of a filament eruption is within reach using a data-constrained magnetohydrodynamics simulation that can be applied to weak active regions in spherical coordinates.
What was once thought to be a single exoplanet-hosting star has now been revealed to be a binary system containing two Sun-like stars; despite this change, the planet’s orbit still appears to be stable long term.
Ground-based observations of Jupiter’s moon Europa suggest that sodium and potassium are ejected from Europa’s surface by a high-energy process such as ion sputtering.
Pairing a five-slit spectrometer with a new decomposition method, researchers demonstrate techniques to study coronal mass ejections while they’re still in the low corona, enhancing space weather forecasting.
As the hot Jupiter HD 80606b passes within 0.03 au of its host star, its spectrum transforms from a featureless blackbody to one with visible spectral features of water, methane, and other molecules.
A new framework successfully mitigates observational noise, inverts even large fields of view in a memory-efficient way, and can resolve small-scale features in regions with strong or weak magnetic fields.
