Reflections on Space: Liquid Mirror Telescopes in Beyond Planet Earth

Imagine a mirror as wide as a football field at the South Pole of the Moon. Instead of polished glass, its surface is made of a reflective liquid, which spins in a circle.

Scientists hope to make this vision into a reality one day by using a liquid mirror to build a giant lunar telescope that would allow astronomers to see farther into the universe than ever before. In the Museum’s special exhibition Beyond Planet Earth: The Future of Space Exploration, visitors can see two liquid mirror telescopes: one featured as part of a Moonscape diorama, the other, an interactive model that can be operated with the push of a button.
