• A new exhibition featuring more than 100 images from space – including images of the colourful dust clouds in which new stars are formed, the aurora on the surface of Saturn and the sight of Earth from the International Space Station – opens at the National Maritime Museum in Greenwich tomorrow. Visions of the Universe takes visitors on a “visual trip through our solar system” with images of the moon, sun, plants and distant galaxies. It looks at the development of telescopy and photography and examines our understanding of our place in the cosmos. Space scientists including Astronomer Royal Sir Martin Rees and The Sky at Night‘s Chris Lintott introduce each section of the exhibition which has at its centre a 13×4 metre curved wall known as the ‘Mars Window’. It has the latest images from NASA’s Mars Curiosity Rover projected onto it. There is a programme of events accompanying the exhibition which runs until 15th September. For more, see www.rmg.co.uk.

• On Now: Coins and the Bible. This free exhibition at the British Museum looks at how money was referred to in the Old and New Testament, and the use of Christian symbols such as crosses or monograms derived from Greek letters on later coins. These include the first coin, dating from about 450 AD, to depict an image of Jesus (the coin, on loan from the Hunterian Museum in Glasgow, is included in the exhibition). There are also early Biblical fragments on papyrus and vellum lent by the British Library and an ivory panel dating from the early 400s AD which includes an image of the purse of 30 pieces of silver Judas received after his betrayal of Jesus. Held in Room 69a, the exhibition runs until 20th October. For more, see www.britishmuseum.org.
