Stephan’s Quintet, a visual grouping of five galaxies located in the constellation of Pegasus, was one of the first images chosen to illustrate the power of the James-Webb Space Telescope compared to that of its predecessor, Hubble. But the JWST not only allows for taking sumptuous images, it also performs spectroscopic analysis that reveals the chemical composition of stars and astrophysical environments. We see an example with one of the supermassive black holes associated with the Stephan Quintet galaxies.
The James-Webb is still at the beginning of its observations and is already giving spectacular results. We even wonder if it is not providing us with elements to decide
Waiting to find out, let us be patient taking note of some results already obtained, such as those related to the famous
