Reply to comment by termsofsurrender in Chinese researchers create the world's largest silicon carbide aspherical mirror by tommos

Not to diminish this particular achievement but that’s kind of a weird take - considering JWST. Also SiC was used for the 3.5m mirror on ESA’s Herschel (Far IR) telescope.

You're right. JWST is an amazing achievement. Herschel's mirror was comprised of smaller mirrors, while the PhysOrg article says that the Chinese made a record-breaking 3m blank.
