(Phys.org) —With this new view of a spectacular stellar nursery ESO is celebrating 15 years of the Very Large Telescope—the world's most advanced optical instrument. This picture reveals thick clumps of dust silhouetted ...

NASA's Webb Telescope components meet 'Big Red'

(Phys.org)—"Big Red" isn't a golden retriever or a NASA engineer, it's the nickname for a small chamber that helps ensure equipment can withstand very cold temperatures that would be experienced in space.

'Giant erector set' supports Webb Telescope test component

(Phys.org)—A new photograph taken inside the giant clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., shows what looks like a giant Erector Set supporting a test component of the James Webb Space Telescope.

Scanning Webb's surrogate eye

(Phys.org) -- Engineer Erin Wilson adds aluminum tape to electrical cables to protect them from the cold during environmental testing of special optical equipment. These tests will verify the alignment of the actual flight ...
