Sunspots appear dark because they are cooler than the surrounding photosphere. Sunspots in the News. Sun exposure: Ultraviolet (UV) light from the sun stimulates the melanocytes. Associated with surface magnetic fields, their numbers increase and decrease in a regular pattern tracing the Solar Activity cycle. They are regions of concentrated magnetic fields that can last from several hours to several months. Which of the following are created by solar magnetic activity? A sunspot is a region of the Sun that has a lower temperature than its surroundings, and with an intense magnetic activity. The photosphere has a temperature of about 5800 degrees Kelvin and a typical Sunspot has a temperature about 3500 degrees Kelvin. Sunspots are regions on the solar surface that appear dark because they are cooler than the surrounding photosphere, typically by about 1500 K (thus, they are still at a temperature of about 4500 K, but this is cool compared to the rest of the photosphere). Sunspots: Sunspots (some as large as 50,000 km in diameter) are areas that appear dark on the surface of the Sun (photosphere).

Why are sunspots darker in color than the rest of the Sun? Sunspots are relatively dark, compared to the rest of the unblemished photosphere, because they have a lower temperature. Sunspots near the equator circle the sun quicker than those near the poles. 42Q. If a sunspot was alone in space it would glow brightly. Student 1: Sunspots are dark because they dont give off any light.

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). Thus from the above observation we conclude that, option is correct. Sunspots are cooler regions on the sun, caused because of a strong magnetic field. A typical spot consists of a dark region called the umbra, surrounded by a lighter region known as the penumbra. Sunspots, temporary disturbances in the Sun's photosphere, are the most visible advertisement of the solar magnetic field. C. magnetic fields absorb most of the light that falls on them. Sunspots. Sunspots can be large or small. They might look small compared to the Sun, but remember the Sun has a diameter of 1.4 million km (870 thousand miles).. An astrophotographer has revealed what he claims is his 'clearest ever photo of the sun'. Andrew McCarthy layered 150,000 alongside mysterious dark sunspots. The dark spots in the images are actually inverted by the photographic process and in reality Sunspots in the News. Because they are cooler than other portions of the Sun's surface, they seem dark.

A solar flare is a violent eruption of plasma from the chromosphere of the Sun Sunspots have a lighter outer section called the penumbra, and a darker central region named the umbra. They continually change in appearance and size. Sunspots appear dark because they are hotter than the sur- rounding gas of the photosphere. Sunspots, prominences, coronal mass ejections, and solar flares. A change in hormones: Pregnant women often get melasma. Dark clouds are also caused by shadows by other clouds, or the cloud itself. A large cumulus cloud lit from behind will shade the surface seen by the observer, and most likely shade other clouds. And again, how dark or gray the cloud appears due to the shading will strongly depend on the brightness of the background. (T/F)

Dark spots move across the surface of the sun, contracting and expanding as they go. Sunspots are dark, irregularly shaped areas which can sometimes be observed on the surface of the sun. Seen from above, storms here on Earth are bright white. Because the Sun is a ball of gas, different latitudes spin at different rates. A change in hormones: Pregnant women often get melasma.
