The latest John Lewis Christmas advert has gone astronomical!

So, if you live in the UK, you know there are two things that indicate Christmas is here: the Coca-Cola lorry and the John Lewis Christmas advert. It's odd to think that the second one has only been going for a few years, yet every year most of us can't wait to see what kind of moving video and brilliant cover song they have done this year.

This year's advert, titled #ManOnTheMoon, is up to the same tear-jerking, inspiring standard as previous years. But to me it's a little bit more special than previous years as it has an astronomical theme to it. The advert follows a young girl who spots an elderly man living on the moon. She tries desperately to get a card and present to him, but nothing seems to do the job. Then, just as you think everything has failed, a helium balloon carried Christmas present starts bobbling along the surface of the moon. Hooray!

Throughout the advert there's some really interesting science and astronomy, which I can't help but look at and wonder how much of it is possible. Could you see a man on the moon? Do helium balloons work on the lunar surface? I've made a video for my YouTube channel going through the science behind the advert, if you're interested in finding out more!

But despite some of the science being a bit suspicious, it's a beautiful advert and it seems to be inspiring people in lot's of different ways. Some people note that the advert is telling us to think of the older, often vulnerable and lonely, generation at Christmas. Others see it as an inspiration for people to get in to astronomy and to get outside this winter and enjoy the night sky. Hopefully it has inspired you in some small way!
