The great infrared observatory of the modern era.
The James Webb Space Telescope is designed to observe infrared light. Because the expansion of the universe stretches light from the most distant galaxies into the infrared, Webb can see objects from the universe's early history.
Webb uses a large segmented primary mirror to gather faint light and a tennis-court-sized sunshield to block the Sun's heat. Operating far from Earth and kept very cold, it can detect faint infrared signals.
Infrared light passes through clouds of dust that block visible light, so Webb can look inside stellar nurseries and study disks where planets form, as well as the atmospheres of exoplanets. Its launch and journey are covered under Space Missions.
How this connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
