Helios by Luke Jerram

Helios by Luke Jerram is at Derby Cathedral from Tuesday 20 October to Saturday 31 October, a seven-metre model of the sun that takes over the space for a few weeks. It's named after the ancient Greek god of the sun, and it's built to a scale of about 1:200 million, so every centimetre represents roughly 2,000 kilometres of the sun's surface. The imagery comes from NASA observations and photographs by astrophotographer Dr Stuart Green, and it pulls together art, science and sound into one installation.

If you've been around the cathedral in recent years, the name Luke Jerram might ring a bell. He's brought two other large-scale works here before: Museum of the Moon in 2019, which drew more than 55,000 visitors, and Gaia, his giant sculpture of the Earth, in 2022. Helios is the opening piece of the cathedral's year-long programme marking 100 years at the heart of the city, so it kicks off a full year of celebrations.

There's also a side to this that's aimed at schools, with interactive activities for Key Stage 1 and 2 children. And throughout the exhibition, the cathedral remains open for worship, so it's not just an art space for the duration.

It's free to enter, though donations of £5 are welcome. You'll find it at Derby Cathedral, 18-19 Iron Gate, Derby DE1 3GP, running from Tuesday 20 October to Saturday 31 October.
