Description |
This image shows the Sun as viewed by the Soft X-Ray Telescope (SXT) onboard the orbiting Yohkoh satellite. The bright, loop-like structures are hot (millions of degrees) plasma (electrically charged gas) confined by magnetic fields rooted in the solar interior. An image of the sun in visible light would show sunspots at the feet of many of these loops. The halo of gas extending well beyond the sun is called the corona. The darker regions at the North and South poles of the Sun are coronal holes, where the magnetic field lines are open to space and allow particles to escape. |

Reason for deletion request:
I (as uploader) want to discuss the problem within a broader audience. It's a complicate case as the satellite is a colaboration of US, UK and Japan. When uploading that file I wasn't aware of the other pages mentioned by Rivi and did investigate thoroughly the NASA pages that indicated PD-US-Gov (no exception disclaimer visible on that pages linked above in the source field). So the problem discussion will evolve in some general thoughts on guidelines how to interpret NASA copyright notices and source info with regard to scientific collaborations of NASA.
