But thanks to high energy X-rays dancing on its surface, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) was able to snap an image that showed the sun displaying a rainbow of colors.

NASA’s Earth-orbiting NuSTAR telescope is usually used to peer at X-rays from high-energy events out in the universe like black holes and supernovae. But recently, the agency decided instead to ...

NASA's Curiosity rover has captured "sun rays" on Mars for the first time, the agency says. The footage was taken on Feb. 6, NASA said, and showed the phenomenon as the sun set on the planet.

NASA's Curiosity on Mars sent back images of sun rays for the first time as the rover begins a study on clouds and their composition high up in the atmosphere.

The sky is blue -- physicists tell us -- because blue light in the Sun's rays bends more than red light. But this extra bending, or scattering, applies just as much to violet light, so it is ...
