This is a photo of an aurora over Iceland that was taken over the Vatnajökull Glacier. Auroras are known to have many colors and shapes just like this one in Iceland. Looking at many pictures of auroras, each and every one is unique in its own way. Auroras are made from the energetic particles from a solar storm causing the gases of the thin upper atmosphere to glow bright colors such as pink, blue, green and red. I would really want an experience to see an aurora one day because of its magnificent beauty and calming effect.
Questions:
1) Why are auroras so rare to see?
2) Why do auroras only happen in certain areas of the world?

I think that this picture is fascinating because it almost doesn't look real. The colors and shapes make this photo look like it was taken in an alternate universe. I agree with you that the aurora has a calming effect. It also looks very mysterious and mystical. It's also interesting how auroras are created, and that each one is unique. I would love to be able to see one for myself.
ReplyDeleteThis picture intrigues me because it looks like green and purple colored clouds and have so many shapes and sizes. The image is almost dream-like. Like many other photos I've seen on this blog, I've learned that millions of small particles can come together to create something beautiful and rare. These auroras are very magnificent and I agree that it would be amazing to see one in person.
ReplyDeleteAuroras only happen at the poles because that is where Earth's magnetic field is weakest. There is a constant stream of "energetic particles" bombarding Earth from the Sun. If it weren't for our magnetic field, life would not be possible on Earth. Some of these particles do get through to the atmosphere at the poles, but only enough to cause auroras and it does not harm us. Auroras are a reminder to me of how harsh an environment space is, and how lucky we are to be on planet Earth that has the perfect conditions, such as the right magnetic field, to make life on Earth possible.
