![]() ![]() Infrared light can penetrate this dusty shroud and to tell scientists what is inside.” ![]() These instruments provide wavelength coverage from 0.6 to 28 microns.Īccording to information from NASA, “infrared observations are important because light emitted from stars and planets just forming lie hidden behind cocoons of dust that absorb visible light. The ISIM’s main instruments, which allow for the incredible images, include its Near-Infrared Camera (NIRCam), Near-Infrared Spectrograph (NIRSpec), Mid-Infrared Instrument (MIRI) and Fine Guidance Sensor/Near Infrared Imager and Slitless Spectrograph (FGS/NIRISS). Its main capabilities are in the ultra-violet and visible parts of the spectrum (0.1 to 0.8 microns). Hubble’s instruments can observe a small portion of the infrared spectrum from 0.8 to 2.5 micrometers or microns. It houses four main instruments that are detecting light from distant stars and galaxies, as well as other planets orbiting other stars. The ISIM is the main payload of the JWST. JWST is NASA’s premier space observatory with its large infrared telescope and 6.5-meter primary mirror. ISIM is one of the three major elements that comprise the JWST’s observatory flight system, its optical telescope element and spacecraft element and sunshield. The intricate detail in the images depicted the capabilities of all four of Webb’s state-of-the-art scientific instruments that are contained in its Integrated Science Instrument Module or ISIM. Webb’s capabilities were designed to “go beyond” what Hubble has already accomplished by looking primarily at the Universe in infrared light, while Hubble studies the Universe at optical and ultraviolet wavelengths with some infrared capability. Webb’s mirror is much bigger in fact than Hubble’s, which allows the telescope to look farther back in time. JWST is NASA’s premier space observatory with its large infrared telescope and 6.5-meter primary mirror and is the successor to the Hubble Telescope. Recently, the James Webb Space Telescope (JWST), NASA’s largest and most powerful space science telescope, began transmitting incredible, never before seen images of distant stars, galaxies and planets down to Earth to the wonder and amazement of JWST mission officials, stargazers and astronomy buffs around the world.
