2023-11-07 20:03:09 Astronomers have discovered the most distant black hole ever detected in X-ray using the Chandra and James-Webb space telescopes. The X-ray emission is a telltale signature of a growing supermassive black hole. This discovery could explain how some of the first supermassive black holes in the Universe formed. This will also interest you … Read more
2023-11-07 07:41:50 Black holes fascinate theoretical physicists because they are probably for a theory of quantum gravity, and probably also for a unified theory of matter and forces like the hydrogen atom and the study of thermal radiation at the equilibrium of a black body were for the discovery of quantum mechanics. Black holes suggest … Read more
2023-08-07 17:36:50 The Hubble Telescope has shown us that there are many instances of large colliding galaxies in the observable Universe, and have been for billions of years. However, quickly, after the discovery of quasars about 60 years ago, people began to think that large black holes might be hiding in the hearts of galaxies. … Read more

2023-07-02 16:19:22 Supermassive black holes have a mysterious origin. They are behind the quasars of the active nuclei of galaxies and the James-Webb telescope has just spectacularly broken the Hubble record for revealing galaxies that once had a quasar. The James Webb Space Telescope (JWST) continues to push the boundaries of observations once accessible to … Read more
