Modeling suggests that drag due to solar flux acting on isolated particles is able to explain the distribution of ringed and ringless worlds in our solar system, even in the absence of additional factors.

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.
