    Sunspots appear black against the solar disk. This is because they are regions (as large as the Earth) of very strong magnetic fields which don't allow as much light to escape as the surrounding area which is EXTREMELY bright! Although they appear black, there is still some radiation coming from them- it is just relatively much less than the rest of the surface radiation.
