How Can The James Webb Telescope Look Backwards In Time?

Nasa has released the deepest and sharpest image of the distant universe ever, taken by its James Webb SpaceTelescope.The image captured thousands of galaxies, including the faintest objects ever observed in the infrared, that appeared in the telescope’s view for the first time.The new James Webb Space Telescope photo captures just a slice of the vast universe, covering “a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground,” according to Nasa.
