Wolf-Rayet stars are known to be efficient dust producers, and the Mid-Infrared Instrument (MIRI) on NASA?s James Webb Space Telescope shows this to great effect. Cooler cosmic dust glows at the longer mid-infrared wavelengths, displaying the structure of WR 124?s nebula. The nebula is made of material cast off from the aging star in random ejections, and from dust produced in the ensuing turbulence. This brilliant stage of mass loss precedes the star?s eventual supernova, when nuclear fusion in its core stops and the pressure of gravity causes it to collapse in on itself, and then explode. As MIRI demonstrates here, Webb will help astronomers to explore questions that were previously only left to theory about how much dust stars like this create before exploding in a supernova, and how much of that dust is large enough to survive the blast and go on to serve as building blocks of future stars and planets.

A fully deployed OTIS, with the secondary mirror extended over the primary mirror, is removed from Chamber A after a successful thermal-vacuum test in 2017. Seen still in the chamber is a sunshield simulator, called the L5 Simulator, representing the fifth and innermost layer of the sunshield. The telescope would be shipped to the Northrop Grumman facility in California to be integrated with the real sunshield. I was suspended on a lift for this shot. Page 119
