Established in 1996, the Spaceguard Centre is a working astronomical observatory concerned with Near Earth Objects (asteroids and comets) and the threat they pose to life on Earth. They work closely with other astronomical organisations around the world, including NASA and ESA and are linked to three robotic telescopes in Australia, Hawaii and the Canary Islands via the Net. The centre has a planetarium with a mini dome which seats 25 and a working model of the solar system. Day and evening tours can be pre-booked.
