NASA’s Near Earth Network helps us learn about the sun’s dramatic temperature differences and activity! The sun’s profound dynamism is showcased in this sizzling, high-energy X-ray image.

Strands of green and blue, captured by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) mission, reveal high-energy emissions that come from gases heated to more than 3 million degrees.

Those observations were overlaid on a picture taken from NASA’s Solar Dynamics Observatory (SDO), which captured the presence of lower-temperature material (around 1 million degrees) seen in the red channels.

NuSTAR sends data to the ground using the Near Earth Network.
