The software used in space travel is sometimes curious. In the case of the JWST, the ISIM is controlled and operated with Javascript. The James Webb Space Telescope (JWST) Integrated Science Instrument Module (ISIM) runs on classic Javascript. The scripts used there are classic because it is a Javascript version from 2003.

The James Webb telescope has just started and is already setting records: it has photographed what is believed to be the oldest known galaxy. A few million years after the Big Bang and long before our solar system, a galaxy is said to have formed, as recorded by the James Webb Space Telescope (JWST). It is said to be the oldest star system discovered to date.

The first images from JWST show the shape and orientation of the primary mirror and wildly scattered stars. (With a trick, the JWST can take a picture of its own primary mirror)Image by NASA.
