In my live video chat session Saturday, I was asked about the Lagrange points, places of gravitational stability. I decided I needed props for this (yes, the return of the Squishy Brain of Science and the Mintie of Science!), and it works even better with pictures, so I created a video for it.
You can learn more details about the Lagrange points at the Montana University site. The Lagrange point images (and the WMAP picture) come from the WMAP website. The JWST picture is from the (duh) JWST site. The portrait of Lagrange is from Wikipedia. Everything else is pure me, baby.
