Space photos of the week: sunspots



It is rare to see an extreme close-up of our Sun, but this photo gives us a chance to look. This part of the sun is called the chromosphere, the second of the three layers of the star. You can see the dark sunspots, along with a skinny thread and lighter regions called Plages, taken from the French word for beach. Slides are temporary characteristics, sometimes lasting only one day, and sometimes the Sun gets rid of them, while other times it is completely naked. Interestingly, the darker sunspots are much colder than the surroundings – they are formed because the magnetic fields are twisted over each other, essentially interrupting the flow of gas and leaving the region cooler.
