Top best answers to the question «Why are sunspots cooler than the surrounding solar surface areas»

  • However, since we are talking about the Sun, cooler means 3800K (6380℉) instead of 5800K (9980℉) Sunspots are cooler because the local magnetic field suppresses convection and prevents heat inside the sun from rising toward the surface. The magnetic field also exerts pressure, which keeps warmer gas away from the area.

FAQ

Those who are looking for an answer to the question «Why are sunspots cooler than the surrounding solar surface areas?» often ask the following questions:

❗ Sunspots are cooler than the surrounding solar surface?

  • Sunspots appear as dark patches in the solar photosphere . These are areas where strong magnetic field has emerged from below the solar surface. The strong magnetic field suppresses the release of heat into the photosphere making sunspots cooler than their surroundings.

❗ What are sunspots cooler than the surrounding areas?

  • Sunspots appear dark to us because they're cooler than the surrounding areas on the sun's visible surface, or photosphere , which has a temperature of about 10,000 degrees Fahrenheit (5,537.8 degrees Celsius ). The dark interior of a sunspot, called the umbra, is about 1,600 degrees cooler than the rest of the sun's surface.

❗ Why are sunspots cooler than the surrounding areas?

I'm not an astrophysicist but I know they are cooler because they are farther away from the source of heat than the surrounding area. The cause of a sun spot is probably excess heat. But as the spot, or eruption, climbs away from the sun it become cooler. It shows as black only because the lenses that are necessary to allow looking at the sun do not allow the smaller amount of light from a spot to be seen. Consider the room where you are. You may be able to see everything in it. But it is not all lit the same and if you put on a pair of sunglasses you might not be able to see areas where you could before. These areas are black, though they are still lit in actual fact.

Are sunspots cooler or hotter than rest of sun?

  • Sunspots are cooler than the rest of the Sun, but many scientists think that when there are a lot of sunspots, the Sun actually gets hotter. This affects the weather here on Earth, and also radio reception.

Why does mercury have a cooler surface temperature than venus?

Venus is hotter than Mercury because its atmosphere is made up of carbon dioxide, which traps the heat. Mercury, on the other hand, has no atmosphere and so the planet can cool itself by emitting infrared radiation.
