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.

The upper limit on the dispersion measure calculated for a fast radio burst implies that the Milky Way’s circumgalactic medium contains less that 100 billion solar masses of material.

Global dust storms on Mars increase the variability in the location of the bow shock and induced magnetospheric boundary, even after storm has subsided.
