This 4k UHD video captures what may be the most spectacular solar event ever witnessed. On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and coronal mass ejection. It produced a dazzling magnetic display known as coronal rain. Hot plasma in the corona cooled and condensed along strong magnetic fields that extended out from the solar surface. Charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, and outlining the fields as it slowly rains back down onto the solar surface.
The video was uploaded at 3840×2160 UHD resolution. The Youtube player cuts that in half, but you can always download it at full res on your spiffy new 4k screen. Or wait till Apple releases its 4k iTV.
