Light moves incredibly quickly, but fast isn't the same as instantaneous.
, telescopes can be time machines, and it all has to do with the speed at which light travels through space.It seems like almost the same thing across smaller distances, like the space between a lamp turning on in your living room, and your spot across that room on the couch. One flip of the switch, and the light is already there.Even something as close on a cosmic scale as the moon, which is a miniscule 239,000 miles away from Earth, is affected by the phenomenon.
"At that distance, [the galaxies'] light tells what the universe was like billions of years ago," the website for the Webb Telescope explains."Since the age of the universe is about 13.8 billion years, these distant observations allow astronomers to measure changes over the lifetime of the universe."NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date.
Cluster SMACS 0723 in particular"is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared."
