The telescope 'guarantees a lot of future-interesting science.'
Dr. Massimo Stiavelli, project lead at JWST talks about the successes and failures of preparing the largest telescope in the world for deployment.
"Some of the results that are reported will need to be verified. It is good that we [can now] see a number of galaxies at redshift — greater than 10 galaxies [which are less than 500 million years old] because it guarantees a lot of future-interesting science for JWST."Recently, astronomical data has been combined across observatories, especially the Chandra observatory and JWST, producing exciting results about celestial bodies.
"I could easily imagine JWST becoming involved with following up a gravitational wave detection, for instance, if one such event appears particularly interesting."One of the difficulties encountered during the JWST's construction was the sunshield, which is a massive triangular that resembles a giant slice of pie. Dr. Stiavelli noted that there were some concerns regarding unfolding the heavy material's layers.
Dr. Stiavelli pointed out that the module and mirrors were exposed to temperatures as low as 40K , which equates to -388F or -233C, while the hot side is only a few feet away from the cold side and experiences temperatures as high as 230F. . This calls for the sunshield to be capable of handling extreme temperature variations.
