An asterisk-shaped feature at the center of a crater on Jupiter’s moon Europa may have similar origins to “lake stars” on Earth; lab experiments show that these patterns can form in Europan ice simulant.

Using the CHARA array, researchers did not detect the hot Jupiter exoplanet Upsilon Andromedae b, despite probing planet-to-star contrast values lower than what is predicted for this planetary system.

Based on the results of 1,024 cosmological hydrodynamical simulations, the galactic subhalo gas mass appears to be the galaxy property most sensitive to the warm dark matter particle mass.

Researchers introduce a next-generation framework that combines a drag-based model with in situ spacecraft measurements to predict the arrival time of coronal mass ejections to within 1 hour.

A novel multi-component outflow structure featuring jets embedded within a global cocoon and disk ejecta provides a unified explanation for phenomena seen in transients observed with the Einstein Probe.

A new method to estimate the full solar magnetic field vector from line-of-sight measurements performs well, allowing for new insights into old data, but does not replace the need for vector-field observing facilities.
