“Our sun can look very different in photographs depending on the wavelength of light you’re trying to capture. Some photographs show the sun as a glowing white ball, while others capture hotter areas in a cold blue color. NASA recently took a collection of sun photos shot at different wavelengths and combined them into the beautiful photo collage seen above (here’s a higher-res version).
The photographs in the collage were all captured by NASA’s Solar Dynamics Observatory (SDO) — the same project that created the “3 years in 3 minutes” time-lapse of the sun that we shared back in April.”
