This image was found of the NASA website, and uploaded by me, Linuxerist. The image has not been modified since its upload, and is therefore kept in its public domain status. The page it was found on is seen above.
The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies. These are not necessarily in the public domain.
The SOHO (ESA & NASA) joint project implies that all materials created by its probe are copyrighted and require permission for commercial non-educational use. [2]
