With the MAVEN spacecraft positioned in Mars’s magnetotail and Tianwen-1 in the upstream solar wind, researchers showed how interplanetary magnetic field rotation drives plasma processes in the magnetotail.

X-ray spectra suggest that a new black hole transient was caught in the process of transitioning from the hard intermediate state to the very high state, and continued in the very high state during later flare periods.

Follow-up observations of a gravitational microlensing event show the source to be a 10-Earth-mass exoplanet orbiting an M-dwarf star, consistent with the discovery article.

A chance alignment between the Parker Solar Probe and Solar Orbiter at 0.11 and 0.88 au from the Sun allowed researchers a rare glimpse into how solar wind turbulence evolves with distance from the Sun.

Disk outflows from a newly formed black hole are shown to produce a bright signal that could power the first peak of certain double-peaked supernova light curves or another kind of transient altogether.

Researchers have performed in an in-depth study of two tidal disruption events that were selected via their radio emission and are visible at optical wavelengths, showing unprecedented intermediate-width spectral lines.
