The related research, presented at the American Geophysical Union meeting in San Francisco this month, could offer scientists a new tool to investigate the mysterious dynamics of the sun. NASA’s Nuclear Spectroscopic Telescope Array was launched in 2012 to study the high-energy physics of the universe, from black holes to supernovas. So when UC Santa Cruz solar physicist David Smith, a NuSTAR team member, asked lead scientist Fiona Harrison whether they could use the space telescope to observe the sun, the...
