Analysis of 11 stars suggests that starspot coverage decreases with age, potentially creating the opportunity to incorporate starspot coverage into isochrone models to improve stellar age estimates.

Twelve of the 49 prime-mission flybys of Europa Clipper are “reconable,” meaning they at least partially meet the requirements for collecting terrain data critical for future spacecraft landing.

The twin-bubble system of N65 and N65b exhibits tell-tale signs of cloud–cloud collision: a bridge, a U-shaped cavity, and a complementary distribution with displacement.

Tidal mixing may play an important role in exoplanetary habitability, especially for planets orbiting close to low-mass stars; tidal mixing equal to 100 times that of Earth’s oceans may be a sweet spot.

Computer simulations reveal the dynamics of planets and gas disks orbiting three-star systems, especially as pertains to planets and disks arranged in a polar rather than equatorial orbit.

Using data from the Wide-field Infrared Survey Explorer, researchers have devised a minimally extincted way to map and measure distances within the Milky Way using Cepheid variable stars.
