WebSep 13, 2024 · Diffraction spikes are typically produced in telescopes which use a secondary mirror held in front of the main mirror; it’s the secondary supports that create them. The JWST has a secondary mirror held in front of the main segmented mirror. There are three supports, one vertical and two angled at 150º to the vertical. WebNov 16, 2024 · Yes, the artifacts are caused by the characteristics of the telescope's optics. The wavelength of light is also a factor, so the diffraction artifacts will manifest differently for different colors. And the way the data is processed also impacts how easily the diffraction artifacts are noticeable.

Explanation WebMar 16, 2024 · While some of the largest ground-based telescopes on Earth use segmented primary mirrors, Webb is the first telescope in space to use such a design. The 21-foot, 4-inch (6.5-meter) primary mirror – much too big to fit inside a rocket fairing – is made up of 18 hexagonal, beryllium mirror segments.
