Solar energetic particles released during solar flares and coronal mass ejections have the potential to seriously harm spacecraft and astronauts; new techniques provide better predictions of the arrival times of these particles.
Three types of neutrino interactions will be investigated at the Jiangmen Underground Neutrino Observatory (JUNO) to detect neutrinos from the production of boron-8 in the Sun’s core.
An optical flare is thought to be the result of the secondary supermassive black hole in OJ 287 impacting the accretion disk of the primary black hole; this potentially repeating occurrence has never been seen before.
A 10-day campaign tested the capabilities of global defense systems to respond to a potential near-Earth asteroid impactor, launching into efforts to characterize and track the object.
A recent search for planets around a 23-million-year-old star finds no planetary companions but does constrain the properties of the debris disk, including its inclination and dust grain size.

Modeling investigates the fate of cosmic rays from blazars; these high-energy particles must survive long journeys through the plasma of the intergalactic and interstellar media to reach our detectors.
