The Sun Moving for Six Months

A compilation of photos of the sun, taken over a period of six months by NASA's Solar and Heliospheric Observatory between January and July, 2009.

Great. A pretty good work. Do you see the very quickly, almost instant, and flashing little lights in the dark?

Thanks for sharing so much. A job much appreciated.

@azimuth361 They both move, but these photographs were taken from a man made satellite, not the Earth. I guess the question is if the speed of the satellite makes the sun's rotation appear faster or slower than in reality or is it in heliostatic orbit?

If any astronomers are reading this, how is it possible to measure the sun's rotation without a fixed point of reference? The Earth's rotation is easy to estimate because it's marked by one cycle of daylight. Do you use other stars as markers?

@LegoFanatic10 They're both moving, actually.

you are dumb the earth is moving not the sun

@MsDragonhawk I doubt it would be slowing in reality. The only thing that could slow it would be an outside force, and I'm pretty sure that even all the planets in the solar system combined wouldn't be strong enough. The rest of the universe exerts too even an effect to cause varying rotation speeds, I propose.

@kierkegaardrulez Is that like Subaru? Impossibru? I want to drive one.

@Trexpass Impossibru!!!!

@MsDragonhawk that is impossibru! an object having no friction and moving parts with a high velocity can not move or slow itself ;)

Assuming the video is a constant speed, is it just me or does the rotation appear to slow every now and then?..

y its blue?
