James Webb Space Telescope
A large infrared observatory with a segmented primary mirror and a sunshield.
Why it matters
Infrared measurements reveal objects and physical processes that visible light alone cannot fully describe.
Specific hardware / optics
Overview
Webb studies faint infrared radiation from distant galaxies, forming stars and planetary systems. Its deployment and thermal design were central to creating an observatory that could operate far from Earth.
Educational reference, reviewed . This page is not a live mission-status report.
How it works
Mirror segments act together to collect light. The sunshield separates a warm Sun-facing side from cold optics, reducing unwanted thermal radiation in infrared observations.
Why it matters
Infrared measurements reveal objects and physical processes that visible light alone cannot fully describe.
