NASA spacecraft officially 'touched' the Sun, scientists say, adding Parker Solar Probe plunged through the unexplored solar atmosphere known as the corona in April
Launched in 2018, Parker was 13 million km from the centre of the Sun when it first crossed the jagged, uneven boundary between the solar atmosphere and outgoing solar wind.
The spacecraft dipped in and out of the corona at least three times, each a smooth transition, according to scientists. But he noted that Parker was moving so fast it covered a vast distance during that time, tearing along at more than 100 kilometres per second.Future coronal excursions will help scientists better understand the origin of the solar wind, he said, and how it is heated and accelerated out into space.
