Simulations show that lava planets with and without clouds have discernibly different spectra, but the ability to discern this difference may be beyond the limits of current instruments.

A deep dive into the Sun’s rotation reveals that the rotational parameters may depend on the phase of the solar cycle, potentially related to the appearance of magnetic structures.

Observations of a particular magnetar — a strongly magnetized neutron star — suggest that the pulsed radio emission sometimes seen from magnetars arises from the outer magnetosphere.

An X-ray shell with a likely age of 20–30 thousand years has been discovered around a compact object; the progenitor star was likely more than 25 times the mass of the Sun.

The wind streaming off the accretion disk of Hercules X-1 is ionized by pulses from the neutron star, and the speed at which the wind reacts to these pulses can be used to measure the density of the wind.

For just the second time, researchers have observed an Earth-impacting meteroroid in multiple passbands prior to the object impacting Earth; this provides a wealth of data about this small near-Earth object.
