For a little remix of @afreeparticle.com's "Rings of Fire", I 3D printed some magnetic hoops that students could stick to the lockers at any height and distance. For some classes, I gave groups a target time and some I gave a target horizontal distance.

A huge prominence is slowly lifting off the Sun's northern hemisphere right now - beautiful stuff. The CME will likely not have an Earth-directed component, this is just eye candy. :)

I will never forget having to edit Jamal’s final, posthumous piece for the Washington Post, after he was murdered.
He was calling for free expression in the Arab world. You can read it here :

What is an auroral substorm?
Substorm patterns are crucial to understand for any aurora chaser. They are what make the aurora "explode" and dance in the sky. Learn more in this article!

I have made this video about electron diffraction which features what I think is a new demonstration which uses three crossed diffraction gratings, a violet laser and glow in the dark film to demonstrate and explain relatively simply why the electron diffraction produces rings at 3 mins 30.
