Sun yields its secrets to Parker Solar Probe

NASA's Parker Solar Probe, having survived its closest encounter so far with the Sun, has sent back a "spectacular trove" of data on its corona, the super-hot outer edge of its atmosphere, scientists said Wednesday.The car-sized probe, launched in August last year, will come within some four million miles (six million kilometres) of the sun's surface during a series of fly-bys at other distances and trajectories over seven years.It is hoped it will allow a better understanding of the solar wind
