Researchers on Wednesday described the first published findings from the Parker Solar Probe, a spacecraft launched in 2018 to journey closer to the sun than any other human-made object. The findings, offering fresh details about how the sun spawns space weather, are reshaping astronomers’ understanding of violent solar wind that can hamper satellites and electronics on Earth.
Earth is roughly 93 million miles from the sun. The probe ventured as close as 15 million miles to the sun to gather the data used in the studies published in the journal Nature. The probe eventually will travel within about 4 million miles from the sun’s surface, seven times closer than any previous spacecraft.
Oscillations in the speed of these charged particles beaming outward from the solar corona have previously been thought to dissipate gradually, much like the waves seen after plucking a guitar string fading from the middle.
