ジェイムズ・ウェッブ宇宙望遠鏡(ジェイムズ・ウェッブうちゅうぼうえんきょう、英: James Webb Space Telescope、JWST)は、アメリカ航空宇宙局(NASA)が中心となって開発を行っている赤外線観測用宇宙望遠鏡である。ハッブル宇宙望遠鏡の後継機 ...

Webb will observe primarily in the infrared and will have four science instruments to capture images and spectra of astronomical objects. These instruments will provide wavelength coverage from 0.6 to 28 micrometers (or "microns"; 1 micron is 1.0 x 10-6 meters). The infrared part of the electromagnetic spectrum goes from about 0.75 microns to a few hundred microns. This means that Webb's instruments will work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range (in particular in the red and up to the yellow part of the visible spectrum).
The instruments on Hubble can observe a small portion of the infrared spectrum from 0.8 to 2.5 microns, but its primary capabilities are in the ultra-violet and visible parts of the spectrum from 0.1 to 0.8 microns.
