Is it true that the James Webb Space Telescope's primary mirror is made of gold?
Yes. A reference encyclopedia entry states Webb's primary mirror segments are gold-plated beryllium with a gold coating for infrared reflectivity, and a NASA page describes the gold-covered primary mirrors. The claim is supported, though the mirror is gold-coated rather than solid gold.
