The James Webb Telescope uses a giant golden mirror made of 18 smaller mirrors fitted together like a puzzle. This mirror collects light from the farthest corners of the universe. It can see a kind of light called infrared, which lets it peek through clouds of dust and gas to see hidden stars being born. A giant sunshield keeps it cool and shaded.

• The James Webb Telescope’s mirror is as wide as a two-story house.
• It can see light from galaxies that formed over 13 billion years ago.
• The telescope is named after James Webb, who led NASA during the early days of space exploration!
