Methane ice dunes on Pluto

The research, which is published in the journal Science suggests that the distant world is more dynamic than previously thought.

Pluto's atmosphere was believed to be too thin to create the features familiar in deserts on Earth.

The findings come from analysis of the startling images sent back by Nasa's New Horizons mission, which flew close to Pluto in July 2015.

After an epic trek through the Solar System that took nearly a decade, New Horizons sped by at a speed of 58,536 km/h (36,373 mph), gathering data as it passed.

In their study, the researchers explain how they studied pictures of a plain known as Sputnik Planitia, parts of which are covered with what look like fields of dunes.

Testimonials on Tripadvisor.

I have been to several shows, the latest being the Tim Peake Show, which showcased the planetarium's new full-dome projection.

All the shows are very well presented by Dr Mason who is a font of astronomical knowledge and makes it accessible, fun and interesting, to all ages.

The planetarium is well equipped with a wonderful star projector and video plus exhibits. Make a visit and relax in one of the comfy reclining seats and watch the heavens unfold above you!

Advance booking is recommended as shows do sell-out.

Went to the Tim Peake presentation on Monday night - absolutely stunning, superbly presented by Dr. John.
I hope that the presentation will be repeated in the New Year, I'm sure lots more people will want to see it when they hear about it.
It perfectly compliments the exciting new display on Tim Peake and the International Space Station at The Novium Museum which has just started and will greatly enhance the reputation of The Novium.

I have been here several times now for various shows over the years and I never stop telling my friends about it and how they must go even offering to book tickets for them to go and reminding them when their show date is due so they don't miss it.
It's an excellent venue, the building is great, loads of artefacts and masses to look at, the main Lecturer Dr John Mason is just amazing, so full of energy and life and passion and really knows what he's talking about and all from his head, no crib sheets or tape recorders.
I cannot say enough what a wonderful place this is to visit and I shall continue to spread the word
