The day of the first published photograph of a black hole – level 3
The first black hole that was photographed is located at the center of the Messier 87 galaxy, which is about 55 million light-years away from Earth.
The photograph was actually a composite of data collected by eight different radio telescopes, including telescopes in Hawaii, Chile, Spain, Mexico, and Antarctica.
Although the photograph was taken in April 2017, it took two years for the team of scientists to process and analyze the data from the telescopes.
The first photograph of a black hole was released on April 10, 2019.
The black hole is 6.5 billion times more massive than the Sun and has a diameter of 40 billion kilometers.
The photograph confirmed Albert Einstein’s theory, which predicted the existence of black holes more than a century ago.
Difficult words: composite (one thing made of different things), diameter (a line from one side of a circle to the other going through the center).
What other discoveries or theories can be made by observing and studying black holes?
