Composite image of the sun’s corona, taken during the total solar eclipse last July.
This is spectacular. The corona is absolutely beautiful, visually as well as scientifically. By all understanding of solar physics, it shouldn’t exist, but there it is. It’s not understood entirely why it exists or how it works, but it has something to do with the magnetic field. Take a look at an example of what magnetic field lines look like and you’ll see the same pattern as appears in the corona.
