The James Webb Space Telescope has identified a supermassive black hole, named Abell 2744−QSO1, existing just 700 million years after the Big Bang. This discovery highlights the surprising early formation of such massive objects in the Universe's evolution.
- 01The James Webb Space Telescope (JWST) focuses on the early Universe's evolution.
- 02Abell 2744−QSO1 is identified as an early supermassive black hole, existing shortly after the Big Bang.
- 03Gravitational lensing has magnified and revealed three images of QSO1, indicating variations in its emissions.
- 04The black hole's mass is estimated to be over 10 million times that of the Sun, making it exceptionally large for its time.
- 05The discovery challenges previous assumptions about the formation of black holes in the early Universe.

The James Webb Space Telescope (JWST) has made a groundbreaking discovery by identifying a supermassive black hole, named Abell 2744−QSO1, that existed just 700 million years after the Big Bang. Initially referred to as 'little red dots,' these objects were found to be early versions of the supermassive black holes that are now known to reside at the centers of most galaxies. Gravitational lensing has played a crucial role in confirming the nature of QSO1, allowing astronomers to observe it as it appeared in the early Universe. The phenomenon has not only magnified the black hole but also created three distinct images of it, revealing variations in its emissions. This suggests that QSO1 has been feeding on varying amounts of material over time. With a mass exceeding 10 million times that of the Sun, this black hole is notably large for its era, presenting new insights into the formation and evolution of massive cosmic structures during the Universe's infancy.
