The Tibet ASγ Experiment Finds Evidence of PeVatrons

Using substantial ground arrays and underground muon detectors, the Tibet ASγ Collaboration has captured evidence of ultra-high-energy gamma rays that are thought to be the result of nuclear interactions between cosmic rays and interstellar gas. Plus, OSIRIS-REx, Ingenuity, InSight, comet 2I/Borisov, and things getting hit (or not) by other things.
