-These mirrors represent a radical departure from the conventional solid-glass mirrors used in the past, producing a new generation of telescopes now exploring the universe in optical and infrared light
-They have a honeycomb structure on the inside; made out of Ohara E-6 low expansion glass which is molded by melting it into a honeycomb interior while spin casting in a custom-designed rotating oven
-Honeycomb mirrors offer the advantages of their solid counterparts - rigidity and stability - but they can be significantly larger, and dramatically lighter
