CAPE CANAVERAL, Fla. (AP) — NASA’s sun-skimming spacecraft, the Parker Solar Probe, is surprising scientists with its unprecedented close views of our star.

Scientists released the first results from the mission Wednesday. They observed bursts of energetic particles never seen before on such a small scale as well as switchback-like reversals in the out-flowing solar magnetic field that seem to whip up the solar wind.

NASA’s Nicola Fox compared this unexpected switchback phenomenon to the cracking of a whip.
