Its two telescopes, the 11.5-foot (3.5 meters) New Technology Telescope (NTT) and the 11.8-foot (3.6 m) telescope both use ultraprecise mirrors to bounce images back from space for analysis.

Cleaning your telescope's delicate mirrors the wrong way is a sure way to damage them. But it's not hard to use the right materials and get those mirrors clean.

Modern telescopes, such as the powerful and multi-talented JWST, sometimes use both lenses and mirrors: a type of hybrid design called catadioptric.
