Scientists have identified one of the most distant dormant black holes ever observed using the James Webb Space Telescope. This discovery opens a new window into understanding how galaxies formed and evolved in the early universe.
The black hole is located in a galaxy named MRG-M0138, situated more than 10 billion light-years away from Earth. Its mass is reported to be approximately six billion times that of the Sun.
Experts believe this black hole existed when the universe was about three billion years old, placing it in a very early period of cosmic history.
How was it detected?
The observation was made using James Webb’s infrared data. Researchers identified the black hole by analyzing the effects of its gravitational pull on the motion of surrounding stars, since the black hole itself does not emit strong radiation directly.
This method is a crucial tool for detecting inactive black holes, as dormant black holes are much harder to spot due to their lack of strong emissions.
New questions about the early universe
Scientists suggest that this black hole may have once been an intensely active quasar. Such a phase could have suppressed star formation within the galaxy and influenced the subsequent development of MRG-M0138.
The discovery could help improve understanding of the connection between the growth of supermassive black holes and the evolution of galaxies. Observations like this are clarifying the complex structure of the early universe.
This achievement by James Webb also highlights the telescope’s capability to study distant celestial objects, providing significant findings that may reduce unknowns about the universe’s earliest epochs.
