The Sun. It warms our Earth while simultaneously reminding us that one day it will balloon in size and roast us all. Of course, if we’re still on Earth in five billion years we kind of deserve it. Before it fries this orb to a crisp, though, it tends to give us some impressive light shows. Without it, we wouldn’t have aurora borealis and we surely wouldn’t have these videos of the Sun firing off flares.
I don’t know about you people, but for some reason these videos remind me of a stomach ache. Then again I’m also a blithering idiot so I may just be seeing things.
