NASA's Parker probe gets help from other telescopes

摘要

The Parker Solar Probe is no stranger to the sun. On January 17, the NASA spacecraft made its seventh close pass of our star, coming within 13.5 million kilometers of the sun's scorching surface. And this time, Parker had plenty of company. A lucky lineup meant that dozens of other spacecraft and Earth-based observatories were trained on the sun at the same time. Together, all of these telescopes are providing unprecedented views of the sun that should help solve some of the most enduring mysteries of our star. Parker's recent orbit was "really an amazing one," says mission project scientist Nour Raouafi of the Johns Hopkins Applied Physics Laboratory in Laurel, Md.
