Lightning starts with a positive fast discharge, followed by an even faster and more extensive negative discharge observed in 3D; signal polarizations slant from the discharge propagation direction and rotate between the two opposite fast discharges; these features can only be due to a cosmic-ray shower that preconditioned the discharge path and guided the discharge current direction.

Artist’s impression of a hypervelocity star ejected from the Large Magellanic Cloud (shown on right). When a binary star system ventures too close to a supermassive black hole, the intense gravitational forces tear the pair apart. One star is captured into a tight orbit around the black hole, while the other is flung outward at extreme velocities -- often exceeding thousands of kilometers per second -- becoming a hypervelocity star. The inset illustration depicts this process: the original binary’s orbital path is shown as interwoven lines, with one star being captured by the black hole (near center of inset) while the other is ejected into space (lower right).
