I am travelling to France today so will be away from my computer for 24 hours or so.
I like this video about Saturn’s rings because it has lots of eminent scientists admitting that they don’t know the answers to some pretty big questions. Celebrate doubt and uncertainty! It’s what keeps driving science forward.

Questions…
- How many planets are there in the solar system?
- What makes a moon different from a planet?
- How long does our moon take to travel once around the Earth?
- How long does the Earth take to orbit the Sun?
