James Webb Space Telescope - Wikipedia
WEBUnlike Hubble, which observes in the near ultraviolet and visible (0.1 to 0.8 μm), and near infrared (0.8–2.5 μm) [ 14 ] spectra, Webb observes a lower frequency range, from long-wavelength visible light (red) through mid-infrared (0.6–28.3 μm).

WEBJan 7, 2022 · The JWST actually looks at two ranges of infrared light: the near infrared and mid-infrared. The near infrared is light with wavelengths very close to visible red light. It's the...
What Is the James Webb Space Telescope? - NASA Space Place
WEB4 days ago · The James Webb Space Telescope is the largest, most powerful space telescope ever built. It will allow scientists to look at what our universe was like about 200 million years after the Big Bang . The telescope will be able to capture images of some of the first galaxies ever formed.
Hubble vs. Webb - NASA Science
WEBHubble can observe in near-infrared light, but it was optimized for shorter ultraviolet and visible wavelengths of light (0.1 microns to 2.5 microns). This difference makes Hubble and Webb a formidable pair of observatories that together cover a broad wavelength range.
Webb FAQs - Science@NASA
WEBThe James Webb Space Telescope, also called Webb or JWST, is a large, space-based observatory, optimized for infrared wavelengths, which complements and extends the discoveries of the Hubble Space Telescope. It has longer wavelength coverage and greatly improved sensitivity.
WEBThe James Webb Space Telescope’s revolutionary technology will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Webb’s infrared telescope will explore a wide range of science questions to help us understand the origins of the universe and our place in it.
