Stephan’s Quintet, a visual grouping of five galaxies located in the constellation Pegasus, was among the first images chosen to illustrate the power of the James-Webb Space Telescope in comparison with that of its predecessor, Hubble. But the JWST not only makes it possible to take sumptuous images, it also performs spectroscopic analyzes revealing the chemical composition of stars and astrophysical environments. We see an example with one of the supermassive black holes associated with the galaxies of the Stephan Quintet.
The James-Webb is still only at the very beginning of its observations and it is already giving spectacular results. We even wonder if he is not providing us with elements to decide
While waiting to find out, let’s be patient while taking note of certain results already obtained, such as those concerning the famous
