For the first time ever, scientists have seen the light from behind a black hole.
The light "echo" was first predicted by Albert Einstein in his general theory of relativity, published in 1916.
This study began with the researchers’ desire to expand our understanding of black hole coronas, which are the source of the X-ray light that often radiates from the vicinity of these objects. . Bright flares of X-ray light are emitted by gas that falls into black holes from their accretion disks, the disks of dust and gas that surround and “feed” these objects.
The team spotted an X-ray flare in I Zwicky 1 that was so bright that some of the light reflected on the gas falling back into the black hole. When that reflected light was bent around the back of the black hole by the object’s extreme gravity, the team was able to spot it using the ESA and NASA space telescopes.
The team didn’t just observe this light, which is the first time it has been directly observed like this; they also took note of how the X-ray light changed color as it bent and moved around the back of the black hole. By observing the light’s journey around the back of the black hole, the researchers hope to understand more about what really goes on that close to these gravitational vortexes.
Following this groundbreaking study, the team aims to create a 3D map of the black hole’s surroundings, according to the statement. They also hope to better understand black hole coronas and explore how the corona of a black hole is capable of producing these bright X-ray flares.Our goal is to create a safe and engaging place for users to connect over interests and passions.
