no, most do
Sunspots are very hot, just not quite as hot as the rest of the sun. Sunspots are cooler because the hot plasma is prevented from rising.
What is true about sunspots
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
No, sunspots are "holes" in the sun's photosphere that allow you to see the layer just below. They are produced by concentrations of solar magnetic flux lines.
Sunspots are actually cooler regions on the sun's surface compared to their surroundings. They appear darker because they are areas of intense magnetic activity that disrupts the normal flow of heat to the surface.
yes
in the sun
Sunspots look darker because they are cooler than the rest of the sun.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
No objects on the sun. but there are sunspots and flares.
Sunspots are cooler regions of the Sun's surface (they are still really bright, they just look dark compared to the surrounding Sun) they are caused by what are basically magnetic field "tangles" stopping the convection that brings heat to the solar surface.
No. The apparent dark areas on the sun are not black holes; they are sunspots. Sunspots are areas of the sun's surface that are not as hot as their surroundings.
