A problem with JWST’s infrared camera detector causes light to bleed from one pixel to another, undermining the quality of its images on some categories of targets. However, work led by two PhD students has provided a solution, which is already being used to multiply the data available from some observations previously considered disappointing.

It’s hard to believe the Hubble Space Telescope was considered a disaster shortly after launch, with misshaping of the primary mirror smearing its images badly. A mission to fit corrective mirrors fixed that problem and gave us 30 years of priceless visions of the universe. Before JWST was launched, astronomers were painfully aware that its far mor
