NASA’s NuSTAR Telescope Reveals Hidden Light Shows on the Sun
Wavelengths of light from three space observatories are overlapped to provide a unique view of the Sun in the image at left.
The high-energy X-ray light detected by one of those observatories, NASA’s NuSTAR, is seen isolated at right; a grid was added to indicate the Sun’s surface.
