NASA’s most ambitious space endeavor in a while, the James Webb Space Telescope (JWST), gathered all the headlines when it launched off into space. It is supposed to learn more about the early universe and unravel its secrets. Quite unsurprisingly, alongside the hype, there are also comparisons being drawn with another space telescope that’s already up there — the Hubble Space Telescope (HST).
But, these two space equipment are functionally different from each other. While HST mainly analyzes heavenly objects using ultraviolet (UV) and visible light, JWST will do this by detecting near-infrared light instead. This sensitivity to infrared wavelength would allow Webb to study the oldest galaxies in the universe. Hubble’s operations revolve around gazing at relatively close galaxies that form much later.
Apart from their respective mission objectives, their dimensions, features, and orbits differ. The James Webb Space Telescope is the successor to the Hubble Space Telescope. It builds upon the work previously done by HST.
James Webb Vs. Hubble: Usage & Specifications
So, those are the basic differences that set JWST and HST apart. While Hubble has been a standout performer for NASA for the past few decades, Webb plans to do the same in the years to come.
