James Webb Space Telescope “City Lights in Space”? The Reality
1. What JWST Actually Observes
The James Webb Space Telescope observes in infrared light, which lets it see:
Distant galaxies forming stars.
Exoplanet atmospheres.
Dust clouds and nebulae.
JWST does not detect artificial lights or cities outside Earth.
2. Why People See “Lights”
Infrared images often show bright spots where stars are forming or galaxies are dense.
These glowing regions are natural phenomena:
Clusters of young, hot stars.
Heated dust and gas.
Nebulae reflecting starlight.
They can look like city lights to the untrained eye, but they are purely natural.
