Auroras on Jupiter

When we first learned about the Northern Lights that occur in Alaska, I was amazed. The images I found on the Internet of the auroras were spectacular. Then, today when learning about Jupiter, I learned that Jupiter also has auroras of its own. Earth’s auroras are caused by solar wind that send charged particles toward Earth’s atmosphere. However, Jupiter fast rotation creates its own auroras by creating a strong electrical field. In order to have auroras, you need particles. For Jupiter, these come from its moon, Io. Like we learned in lecture today, Io has volcanoes that send particles toward Jupiter that are captured at Jupiter’s poles, creating a constant aurora. The colors of Jupiter’s auroras are not at spectacular as they are on Earth, but they are still just as interesting!

That's really interesting to think about the different ways Auroras can occur. I am surprised to learn that Jupiter's are less spectacular than Earths. I'm not exactly sure why but I would hypothesize that Jupiter's would be far more spectacular than Earths. It is also interesting that to know that Io is credited in helping Jupiter have Auroras. Very cool information though! It definitely ties into what we are learning very well!
