An over-massive galactic black hole is a supermassive black hole that has a mass that exceeds the expected limit for its host galaxy. This means that it is significantly larger and more massive than other black holes found in similar galaxies.
This over-massive galactic black hole was discovered using a combination of observations from different telescopes. Scientists used data from X-ray, infrared, and radio telescopes to confirm the presence of the black hole and determine its mass.
This discovery challenges our current understanding of how black holes form and grow. It also suggests that there may be other factors at play in the growth of black holes, such as mergers with other galaxies.
No, this black hole is located in a distant galaxy and poses no threat to Earth. Black holes do not actively seek out and consume objects, and their effects are only felt when objects come too close to their event horizon.
Scientists will continue to study this black hole and others like it to better understand their formation and growth. They will also use new and advanced technologies to gather more detailed data and possibly uncover more over-massive galactic black holes in the future.
