The missing middle. These plots show that the sun shot light called high-energy gamma rays from its middle during a period of low solar activity (from about August 2008 to the end of 2009, left ...

The sun is emitting less iron, as seen in X-rays, than the models predict. Astronomers now say they're a step closer to figuring out why.

It's easy to think of the sun as simply a bright, orange ball. But thanks to high energy X-rays dancing on its surface, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) was able to snap an ...

The Fermi Gamma-ray Space Telescope There’s something wrong with the sunshine. A nine-year survey of the sun’s gamma rays has turned up two surprises: an unexpected dip in low-energy gamma ...

Astronomers have discovered the highest-energy light rays ever observed from the sun in a finding that raises more questions on how such radiation is emitted from its solar atmosphere.. Since the ...

The sun cannot be this bright at these energies.'" Their eyes, however, were not fooling them — the Sun was, per their readings, shooting off a ton of gamma rays that are between one and 10 ...

The gamma-ray emissions from the poles were particularly concentrated in June 2014, when the magnetic poles of the sun reversed, a phenomenon that happens every 11.5 years or so at the peak of ...
