Are sunspots visible due to redshift?

Question

Are sunspots visible due to redshift?

Answer 1

These are two completely unrelated items.

Sunspots are cooler regions on the photosphere of the sun.  They give off extremely strong magnetic fields.

Redshift is detected by an object moving rapidly away from you (or you from it) so that the wavelengths are "stretched out" making an object appear closer to he red end of the electromagnetic spectrum.

Answer 2

Sunspots are visible because they are a different colour from the rest of the sun. It has nothing to do with redshift.

Answer 3

Sunspots are somewhat less bright than the rest of the sun's surface, due to being cooler. However, they are by no means dark. When viewed with a solar filter, they are not bright enough to penetrate and show up so they appear dark when viewed this way.

Answer 4

sunspots only appear dark when compared to the brightness of the rest of the sun.....

that sun spot if put next to our moon would still be 10x brighter then a full moon...
