Helios

Helios is a new touring artwork by UK artist Luke Jerram. Measuring seven metres in diameter, the artwork features 72dpi detailed imagery* of the Sun’s surface. At an approximate scale of 1:200 million, each centimetre of the internally lit spherical sculpture represents 2000km of the Sun’s surface.

It is very dangerous to look at the Sun directly as it can damage our eyesight, so Helios provides a safe opportunity for the public to get up close to, and inspect its extraordinarily detailed surface, including sunspots, spicules and filaments. The sculpture also features the source of the solar flares which caused the Northern lights to be visible from the UK in May 2024.

The installation is a fusion of solar imagery, sunlight and a specially created surround sound composition by Duncan Speakman and Sarah Anderson.

Helios, in ancient Greek mythology, is the god who personifies the Sun. He drove a four-horse chariot across the sky each day, giving the earth its hours and seasons.

* The imagery for the artwork has been compiled using photographs of the Sun provided by Astrophotographer Dr Stuart Green (taken between May 2018 to June 2024) and NASA observations of the Sun, with guidance from solar scientist, Professor Lucie Green of University College London (UCL).

Booking online in advance is recommended but not essential, but during busy times those looking to pay on the door may have to wait and some sessions will inevitably sell out in advance.

Last entry, 30 minutes before the end of each day. Dogs on leads welcome.
