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.

If Mars’s dust was produced via rock-on-rock grinding of basalt, as may happen at the base of a glacier, the fine dust created this way would have influenced the red planet’s climate.

Now confirmed, TOI-6324b is an ultra-short-period planet with a mass and estimated core fraction similar to Earth; JWST could reveal its surface mineralogy and possible tidal deformation.

A narrowband imaging survey of more than 600 galaxies has demonstrated that tidal interactions, ram pressure stripping, and starvation are at play for galaxies situated within a filament environment.

A survey overview and science highlights are presented for CEERS, which has contributed significantly to JWST’s “First Light” and “Galaxy Assembly” core science drivers.
