This is not a Jackson Pollock.
French skywatcher Jean-Pierre Brahic snapped the shot in February 2011, capturing an active solar region with insanely strong magnetic fields. According to Space.com, the image was created by combining multiple exposures of the same region, in order to create a view that would otherwise be unseeable.
Active regions of the sun are defined by their strong magnetic fields. As a result, solar flares and coronal mass ejections (CMEs) are often associated with the region, and they appear bright in X-ray and ultraviolet images.
These aren't the only amazing shots of the sun. NASA's Solar Dynamics Observatory has captured some amazing images of the sun at a number of different wavelengths. As a result, the organization has been able to share stunning, constantly updating images of the star, available for all to see. Check out NASA footage of a solar flare here, and view a solar flare eruption image here.
Note: As Space.com warns, never stare directly at the sun.
