JWST's MIRI Instrument is Having Problems Again By Nancy_A
They also compared how MIRI’s spectroscopy mode is working now versus how it worked earlier in the mission and they found that at the longest wavelengths, the throughput, or the amount of light that is registered by MIRI’s sensors, has decreased since the instrument was turned on and commissioned last year.
Cassiopeia A is a supernova remnant. It has been observed many times. This new image uses data from Webb’s Mid-Infrared Instrument to reveal Cas A in a new light. Credits: NASA, ESA, CSA, D. D. Milisavljevic , T. Temim , I. De Looze . Image Processing: J. DePasquale . It allows the telescope to see in the wavelength range from 5 to 27 micrometers. The instrument has 4 modes: imaging, medium-resolution spectroscopy, low-resolution spectroscopy, and coronagraphy.
In the meantime, MIRI observations will continue as planned, and engineers will determine if there’s a way to work around this issue, too.
