Start your journey through space at the National Maritime Museum, where you can meet real astronomers, ask big questions about the Universe, and immerse yourself in breath-taking astrophotography

Then take a short stroll through Greenwich Park to the Royal Observatory to get closer to the Moon than ever before; explore its surface and feel the craters beneath your fingertips.  

Whether you've been wowed by Artemis II, inspired by Project Hail Mary, or you're a life-long space enthusiast, make the voyage to Greenwich this summer to check these must-see experiences off your intergalactic itinerary.

Astronomers Take Over

Astronomers Take Over is a hands-on, interactive, family-friendly experience, perfect for anyone with a love for all things space! Inside, you can meet real astronomers, try your hand at landing a Mars rover, use a starlight splitter and step inside an awe-inspiring ‘galaxy box’ to find out just how amazing our Universe is.

Plus, while the Peter Harrison Planetarium is closed for refurbishment, we’re bringing you an alternative planetarium experience at the National Maritime Museum, with all the excitement of our world-class programming, but in a more intimate space.

Mirror Moon

Royal Observatory Greenwich

Take a walk around the far side of the Moon this summer, as a new art installation by artist Luke Jerram comes to the Royal Observatory.

Called Mirror Moon, this scale model is 2m in diameter and made from mirrored stainless steel. Mirror Moon uses highly accurate topographical NASA data of the lunar surface to transport the Moon from hundreds of thousands of miles away – to right beneath your fingertips. You'll be able to touch, walk around, explore the lunar craters and 'oceans', and see yourself reflected in the Moon's surface; don't forget your cameras for that all-important lunar selfie!

Perfect for: Art, sculpture and space enthusiasts of all ages

What the press says

'Every year, I leave this exhibition feeling insignificant in the grand scheme of the universe' 

  • Londonist on ZWO Astronomy Photographer of the Year exhibition

'[The astronomers'] enthusiasm and knowledge are wonderful. It’s just incredibly rare to go to an... exhibition and find large numbers of helpful staff on hand and heavily involved. It turns out that the ultimate interactive display… is a person.'

  • Andrzej Lukowski, Time Out on Astronomers Take Over 

What our visitors say

'The staff really stood out. They are walking around in astronaut-style suits, and they actually take the time to explain what is going on in a way that children understand. It does not feel forced or scripted, it just feels like they genuinely enjoy what they are doing, which makes the whole experience better.'

  • Natasha F, Kiddo Adventures on Astronomers Take Over

What our Facebook followers say

'I went yesterday with a four-year-old, a seven-year-old and two nine-year-olds. We had a great time! The older ones whizzed round and enjoyed reading the info in the exhibition; the younger ones really enjoyed the activities. The lounge area gave them a chance to sit and try the spectrum activities then move on to the Moon Hub. 

'The staff were all enthusiastic; all the kids learnt something; it was fun!'

  • Jo Smithson, Facebook review of Astronomers Take Over
