What are the black spots in the Sun?

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.

Why does the Sun have dots?

The Sun has a magnetic field that gets twisted around inside the Sun as it spins. There are places on the Sun where this magnetic field rises up from below the Sun’s surface and pokes through, creating sunspots. Sunspots are magnetic and often have a north and south pole like a magnet.

Why do dark spots appear on the Sun?

Ultraviolet (UV) light speeds up the production of melanin, a natural pigment that gives skin its color. On skin that has had years of sun exposure, age spots appear when melanin becomes clumped or is produced in high concentrations.

Do sun spots go away?

Most sunspots fade somewhat over time, but they will typically not disappear completely because the skin has been permanently damaged. There are, however, several treatments to diminish the appearance of sunspots. Bleaching creams and acid peels can make the appearance of sunspots less obvious.

What happens to the Sun every 11 years?

The Short Answer: The Sun’s magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun’s magnetic field completely flips. This means that the Sun’s north and south poles switch places. Then it takes about another 11 years for the Sun’s north and south poles to flip back again.

Are Sun Spots bad?

Despite their appearance, sunspots are benign and not a sign of cancer. Although sunspots are harmless, some people may choose to treat them for cosmetic reasons or to improve their self-esteem.

Are sunspots bad for the sun?

Sunspots are generally harmless and don’t pose any health risks. Typically, the only reasons to remove sunspots are cosmetic ones. However, it is important to know the difference between sunspots and signs of skin cancer caused by sun damage. The most common type of skin cancer is melanoma, and it is the most serious.

When should I worry about sun spots?

Any freckle, mole, or sunspot that changes in color, shape, or size is suspicious. A tan spot that becomes mixed with red, black, or pink areas needs to be checked out. A small freckle that becomes much larger or develops an irregular border should be seen by a physician.

Can freckles be red?

Freckles appear when melanin, the pigment that gives skin its color, builds up under the skin. Freckles may look brown, red, or tan.

Are freckles bad?

Freckles are not harmful or the sign of a health problem. They’re just pigment cells (cells that contain color) that are contained within the skin in small batches. Freckles are usually tan or light brown, flat, and very small. Sometimes they overlap and run together so they may look larger.
