What r sunspots?

Question

ANSWER IN DETAIL WITH PICTURES

Answer 1

They are the visible sign of major disturbances in the Suns atmosphere that sometimes result in solar flares and millions of tons of matter are ejected along with heavy cosmic rays. The disturbance results in the exposure of relatively cooler layers of the Suns atmosphere being exposed at the surface. These appear as dark spots through our telescopes. Or to the naked eye when using safety rated Sun filters for naked eye viewing.

Answer 2

i'm not sure wat they are but i heard that pouring bleach water on them helps, yes it will sting them but it will help all you need is to fill the bleach cap up and pour it in to a gallon of water a couple time and just pour it over the spots!

Answer 3

A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings and has intense magnetic activity, which inhibits convection, forming areas of reduced surface temperature. They can be visible from Earth without the aid of a telescope. Although they are blindingly bright at temperatures of roughly 4000-4500 K, the contrast with the surrounding material at about 5800 K leaves them clearly visible as dark spots, as the intensity of a heated black body (closely approximated by the photosphere) is a function of T to the fourth power. If a sunspot was isolated from the surrounding photosphere it would be brighter than an electric arc

Infact A  huge sunspot as big as the surface area of thirteen Earths is growing on the Sun and has now rotated with the Sun to face the Earth. The sunspot, in the region designated AR 9393, is the largest of the current solar cycle, making it the biggest to appear in ten years

Answer 4

Sun spots are places on the surface of the sun, which are slightly cooler as others. Because they are cooler, they appear darker as the rest of suns surface - while still glowing hot white at 4500-4800°C, they are 1000° cooler as the rest of the surface and appear black on typical filters for optical telescopes.

One important aspect of them is that while they are cooler as the rest of the surface, they are actually the spots of the highest activity - chaotic magnetic fields have their poles inside them and this magnetic activity inhibits the usual convection of hotter material from the core of the sun to the outside.

The number of sunspots on the surface of the sun is a sign of solar activity - the more sunspots, the more active is the sun, that's why counting sunspots is used as one way to measure the activity of the sun, additionally to observing the 10.7cm radiation.
