By combining ground-based and space-based solar observations, researchers found that solar minimum solar wind predictions require higher source-surface heights than solar maximum predictions.

The combination of gravitational wave emission, magnetic dissipation, and tidal interactions should cause the beat clock period of the CHIME/ILT J1634+44 system to change by tens of seconds per year.
The Hayabusa2 spacecraft could be rerouted to collide with asteroid 2024 YR4 and impart a velocity change of a few centimeters per second (though thankfully, such an intervention is not necessary!).
New millimeter-wavelength observations reveal four new outflow lobes in addition to a previously known central bipolar jet; the new lobes have chains of knots, which are a sign of episodic ejection.
New constraints on the mass of V1674 Herculis from X-ray observations place the white dwarf around 1.09 solar masses, well below the near-Chandrasekhar mass proposed in previous works.
Resonance between gravitational waves and magnetic fields may produce a faint radio signal in pulsar magnetospheres; current searches are approaching the sensitivity necessary to detect this signal.
