What a difference! These two images of the sun’s outer atmosphere, or corona, were taken about 20 months apart. The sun is quiet in the picture at left, taken in January 1997. In the picture at right, taken in November 1998, the sun is more active. When the sun’s activity increases, more sunspots become visible. Credit: SOHO (ESA & NASA)

I found this article quite cool. If you guys remember Niko, he is very scientific and amazing at astronomy, he told me (as most of you might know) that the magnetic poles might switch soon. That will lower the level of the atmosphere and if a sun flare occurs in that time, than the entire earth will be turned into the Sahara. However, the chances of that happening are about 1 in 1,000,000,000.
I think this article was very interesting. Even though it could possible only be delayed two years, there would still be weird seasons. Luckily we don't live in the coldest or hottest part of the world. There are so many cycles in the universe! Ben, what do you mean be Sahara?
Nice point Ben. I think you did get it wrong though. If we get into that situation, the Sahara will probably get it's greenery back.
I think it would be terrible if the whole world were to have colder winters, although the upside is it could slow global warming for around ten years. And Ben, isn't it actually the other way around like Rehaan said?
I thought this article was really interesting. I would have liked a little more information about what will happen if the sun does go off its cycle. It didn't really give us a lot of information about that. And Rehaan, Ben could actually be right because solar flares are basically radiation, which would be more likely to turn the whole world into a desert like he said.
It's super cool that the sun does a natural change every year then like resets and does it again.
I really liked this article and thought it was very interesting. I agree with Luca that it would stop global warming for a few years. I don't think that the winters would be as cold as they were when this happened in 1645-1715 because I think our atmosphere would hold in some of the heat so that it wouldn't be so cold. I never knew about the magnetic poles and how they might switch, so I really can't say much about that. I really thought that the first set of images was amazing. I would have never thought that our sun could just tone down, even though in this hot weather, I think it would be kind of nice.
The heat would completely burn through all of the plants, so it would turn the world into one vast desert.
I thought this article was pretty cool. I had no idea that the sun hibernates, and personally, I think it would be nice to have a break from these 103 degrees fahrenheit days like we're having now. Like Luca said, it would also help stop global warming.
I really like this article. I think it's sort of weird that the sun's going into hibernation, because the sun's so hot, and I wonder what's going to happen when the sun does hibernate.
