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.
In a cosmology framework that proposes the universe began with a period of contraction before the Big Bang, researchers find that high-frequency gravitational waves oscillate in a way that is potentially detectable.
Polarization measurements show evidence of shock compression and possible interaction between a supernova remnant and previously formed circumstellar shells from the progenitor’s mass loss.
