Mike Every knows about grinding glass—and he doesn’t like it. The second-year physics major from Saugerties, N.Y., is an amateur telescope maker with an idea for producing lightweight mirrors out of ...

(Nanowerk News) Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space.

Mirrors are a critical part of any space telescope, and the James Webb Space Telescope’s mirrors are made of a special element that will enable it to withstand the rigors of space and see farther back ...

Can space telescopes be improved for future astronomy studies? This is what a researcher from the Max Planck Institute for Extraterrestrial Physics hopes to find out as he developed a method of ...

When scientists are looking into space, the more they can see, the easier it is to piece together the puzzle of the cosmos. The James Webb Space Telescope’s mirror blanks have now been constructed.
