Looking on the bright side, MIRI can still make observations in other modes, and NIRCam - the instrument that captured the telescope’s view of Neptune - isn’t affected by the glitch. The cutting-edge, 10 billion James Webb Space Telescope ( JWST) shared its debut image with the world on July 12, 2022, peering deeper into the universe than any telescope before it. Because of the snag, the JWST team has paused MIRI’s observations in its medium-resolution spectroscopy mode until an adequate solution is found. The most recent issue involves increased friction in one of the mechanisms for JWST’s Mid-Infrared Instrument, or MIRI. There have also been glitches to deal with, and unlike the Hubble Space Telescope in its heyday, there’s no way for a repair team to make a service call.
It’s been eight months since the 6-ton telescope arrived at its observation point, a million miles from Earth, and astronomers have been wowed by the results so far. And this month, JWST captured its first images and spectral data from Mars. Last month, astronomers unveiled the telescope’s first pictures of Jupiter as well as its polar auroras and faint rings.
Infrared detectors are also well-suited for looking within dusty nebulas and analyzing the atmospheres of alien planets.īut as the images released today illustrate, JWST can also produce fresh views of the celestial objects within our own solar system.

JWST’s infrared imagers are optimized to look at the frontiers of the cosmos - including extremely redshifted objects near the edge of the observable universe.
