The James-Webb is located on one of the Lagrange points, where, to put it roughly, the forces of the Earth and the Sun on it are balanced, allowing it to maintain a relative position with respect to these stars without consuming much of fuel, while being relatively protected from the infrared radiation which would disturb its observations. It is 1.5 million kilometers from Earth. Knowing that the radio waves carrying the James-Webb data travel at the speed of light, or about 300,000 km/s, it therefore takes about 5 seconds for this data to reach Earth. It has two antennas to communicate with the Earth, the so-called “high gain” one offering a rate of 3.5 megabytes per second. I do not know in what form the data is transmitted, and therefore cannot tell you how to translate them into images such as we can consult them on our screens, after the different wavelengths have been translated into colors appreciable by the eye. human.
