In 1610, soon after the telescope was invented, Galileo became the first man to see spots on the sun. Through the telescope, the sunspots look like dark holes in the sun’s white disc.
Sunspots may & observed on almost any clear day. They vary greatly in size. Some ap ar like mere specks on the sun’s surface. One very large spot was about 90,000 miles long and 60,000 miles wide. Groups of sunspots are known to measure 200,000 miles in length.
Astronomers are fairly sure that sunspots are electrical in nature because of certain effects they produce. One astronomer has shown that they are tremendous whirls of electrified matter that come bursting out from the interior of the sun in pairs like the ends of a U-shaped tunnel.
Sunspots, or their release of electrical energy, send beams of negatively charged electrons shooting into space. Some of these electrons enter the earth’s atmosphere and produce certain electrical effects.
One of these effects is the “aurora borealis” (or Northern Lights). Electrical energy from sunspots also disturbs radio transmission. These electrons also seem to increase the amount of ozone in the upper atmos- phere. This extra ozone may absorb more of the sun’s heat than usual, so sunspots may have a bearing on our weather.
Most sunspots only last a few days, but some last two or more. They increase in number, then diminish, in a regular cycle which runs about 21a years. Records of sunspots have now been kept for more than 100 years and we are still learning about what they are and how they affect us.
How Do You Get Rid Of Sun Spots?
1. Laser and intense pulsed light.
2. Freezing (cryotherapy).
5. Chemical peel.
Sunspots are like little blemishes on the surface of the sun. They appear mostly at the sun’s poles where the magnetic field of the sun acts to create a little hole in the photosphere. But sunspots can also appear near the equator, where the sun’s magnetic field is weaker. They are usually dark, but sometimes have a lighter area or a starlike shape, and may be accompanied by other bright spots. They appear almost all of the time but are more prevalent during a solar minimum. They are due to the sun’s magnetic field, which pushes plasma up against the photosphere, creating a sheet of plasma.
Every year, many people begin to wonder about sunspots. But, what are sunspots? Sunspots are dark patches that appear in the Sun’s photosphere, the region of the Sun’s atmosphere where light and heat originate. They are caused by eruptions on the Sun’s surface, and they can last from a few days to a few weeks.
Sun is a mysterious object: something that hurtles through space every 93 million miles, sending our planet into a frenzy of mass destruction. It also sends us into a frenzy of mass destruction, because 26% of the sun has been discovered to be super-hot — and it’s all the more interesting to us because this is a sun with no sunspots.
