Henry from MinutePhysics has recorded a new, astronomically correct version of the kid's lullaby Twinkle Twinkle - and it's our favourite children's song in a long time.

In it, he takes us through why stars twinkle and what happens when they become supernovas, all to a pretty guitar melody.

Our favourite line? "Twinkle twinkle little star, you must be a small pulsar. Out away from Earth you drift. This is known from your red-shift."

Oh, and there's a black hole mention and, of course, a comet thrown in there too for good measure.

So watch it above and play (or sing it) to your children and get them inspired about the wonder of space and science. 

We just wish this version was around when we were little.
