  • Description

    Technicians are putting the finishing touches to what will be the world's most optically-perfect telescope. They are working at a United States' observatory near Tucson in Arizona on a large ground mirror which will form the heart of a new observatory in Chile.

    Scientists have long wanted to look beyond the galaxies visible by normal telescopes. The best method they have found is by measuring the light radiated by the unseen galaxies, The pulses are captured by the mirror, and scientists can measure their density and frequency, thus learning about the age composition of the star itself.

    For the past few weeks the mirror has been buffed continuously to make the surface as smooth as possible. The glass is covered with polishing rouge and, when the process is finished, it will make the surface smooth to within two and a half millionths of an inch.
