Text, MYTH versus REALITY

Myth side

Text, The James Webb Space Telescope can see the same things the Hubble Space Telescope sees.

Reality side

Text, Hubble sees mostly visible light, while Webb is designed to observe infrared light. While Hubble can view some wavelengths of the infrared sky, Webb’s vision extends much farther into the infrared than Hubble can observe. Webb will also have a much larger mirror than Hubble. It can see fainter objects, more-distant objects, and stars that are hidden from Hubble's view.
