We Have the first image of the supermassive black hole, Sagittarius A*, at the center of our Milky Way galaxy. share by the scientists from the Event Horizon Telescope (EHT) .
The mystery of the supermassive black hole at the center of our Milky Way has finally been solved. The world has been gifted with the second photo ever of a supermassive black hole, released after years of research. The scientists at Event Horizon telescope (EHT) released the first image of Sagittarius A*, the supermassive black hole at the center of our galaxy. This was another major announcement after the first image of a black hole was announced in 2019. So let's know more about this important announcement in detail.
For years supermassive black holes have been a mystery. How these supermassive black holes were formed in the early universe is still a mystery that astronomers are trying to figure out. Scientists have long believed that a supermassive black hole hidden deep in our galaxy's chaotic central region was the only possible explanation for the strange things that occur there, such as giant stars slingshotting around an invisible something in space at a significant fraction of the speed of light. However, they have been cautious to declare so explicitly. When astronomers Reinhard Genzel and Andrea Ghez received a portion of the 2020 Nobel Prize in Physics for their work on Sagittarius A*, their citation said that they were honored for "discovering a gigantic compact object at the center of our galaxy," not the finding of a "black hole.
The EHT uses a method known as very long baseline interferometry (VLBI), which unites radio observatories on different continents to build a virtual Earth-size telescope.
The first final result from that work has already been seen: M87*. During the same campaign, the team collected raw data for the Sagittarius A* photograph, but turning those observations into an actual image took significantly longer.
