A full moon will appear in the skies over Britain on Christmas day, for the first time in decades.

The last time there was a full moon on 25 December was 1977, and there won't be another one until 2034 - so unless you want a long wait to catch a sight of this rare astronomical occurence, it's a good idea to head outside and look up on Christmas.

The full moon, which is the last of the year, is called the Full Cold Moon because it occurs at the start of winter.

According to Nasa (who know a lot about this sort of thing), the full moon will peak at 11:11pm GMT, proving a great view in the night sky.

Unfortunately, things are looking quite cloudy on Christmas day across much of the UK, so you might not get the best uninterrupted view.

Large bands of rain over most of Wales and north west England could hide the moon from view, but the clouds should be a bit thinner across the rest of the country - so there's a chance you'll catch the full moon peeking through.

LRO captured the sharpest images ever taken from space of the Apollo 12, 14 and 17 landing sites. Images show the twists and turns of the paths made when the astronauts explored the lunar surface. NASA says the image brightness and contrast have been altered to highlight surface details. Reuters Moon pictures show traces left by astronauts This annotated image released by NASA shows an image of the Apollo 17 landing site taken by the Lunar Reconnaissance Orbiter Camera(LROC) in orbit around the Moon. The twists and turns of the last tracks left by humans on the moon crisscross the surface in this LRO image of the Apollo 17 site. In the thin lunar soil, the trails made by astronauts on foot can be easily distinguished from the dual tracks left by the lunar roving vehicle, or LRV. Also seen in this image are the descent stage of the Challenger lunar module and the LRV, parked to the east.

The north east coast, eastern scotland and Northern Ireland will have clearer skies compared to the rest of the UK, so they'll be the best places to spot the moon.

With the moon so clear in the sky, it's worth remembering the number of man-made spacecraft currently working around it.

Nasa's Lunar Reconnaissance Orbiter has been orbiting the moon since 2009, and constantly beams back important information about the Earth's closest neighbour - including amazing pictures of human landing sites on the moon, with images released in 2011 showing surprisingly sharp images of boot tracks, moon buggy trails and landers left behind after the Apollo 12, 14 and 17 missions.
