Liquid-mirror telescope has quality advantage
Moon-based liquid-mirror telescopes
Low-temperature ionic liquids (below 130 kelvins) have been proposed as the fluid base for an extremely large-diameter spinning liquid-mirror telescope to be based on the Moon. Low temperature is advantageous in imaging long-wave infrared light, which is the form of light (extremely red-shifted) that arrives from the most distant parts of the visible universe. Such a liquid base would be covered by a thin metallic film that forms the reflective surface.
