After researchers crashed a spacecraft into it in September 2022, the Didymos–Dimorphos binary system showed a lower degree of polarization for months.

A new database will aid in the study of presolar grains, which are formed during the late stages of stellar evolution and give a detailed look at the history of local stellar nucleosynthesis.

Researchers show that interpretations of gravitational wave signals are sensitive to the models used to generate them, especially in cases where one or few black hole formation channels are considered.

Sometimes, stars in binary systems are so close that they actually touch, eventually leading to a merger that may be a luminous red nova — a class of explosion in between classical novae and supernova.

The Imaging X-ray Polarimetry Explorer gives a new look at 4U 1630–47, a binary system likely containing a star and a black hole, allowing for new insights into the nature of the X-ray-emitting plasma.

The ice shell on Saturn’s moon Enceladus appears to be thicker at the equator that at the poles, which simulations suggest is due to a non-equilibrium state or tidal dissipation.
