High-speed particles spew out of the sun like water from a shower head, scientists reported on Wednesday.
Data from the Parker Space Probe, a NASA spacecraft that launched in 2018 and is now swooping in to gather readings of the sun’s outer atmosphere, or corona, is providing clues about how the sun generates the solar wind — a million-miles-per-hour stream of electrons, protons and other charged particles rushing outward into the solar system.
The solar wind research ties into a mystery that has long perplexed scientists: Why is the corona, where temperatures soar to millions of degrees, so much hotter than the surface of the sun, which is a relatively cool 10,000 degrees Fahrenheit?
The Parker probe is named after Eugene N. Parker, a University of Chicago astrophysicist who first predicted the existence of the solar wind in 1958.
