Swedish Solar Telescope. View of the top of the Swedish Solar Telescope tower at the Roque de los Muchachos Observatory, La Palma, Canary Islands. The turret of this 16-metre-tall tower is capped with a 0.5 metre mirror that collects the Sun's rays and focuses them onto an array of lenses and guides at the bottom of the tower, where they are analysed. This telescope is operated by the Royal Swedish Academy of Sciences (KVA).
