The day of the first published photograph of a black hole – level 2
The first black hole ever photographed is located at the center of the Messier 87 galaxy. It is about 55 million light-years away from Earth.
To produce the photograph, data from eight different telescopes were analyzed. These included telescopes in Hawaii, Chile, Spain, Mexico, and Antarctica.
The photograph was taken in April 2017, but it took two years for the team of scientists to analyze the data from the telescopes.
The first photograph of a black hole was published on April 10, 2019.
The black hole is 6.5 billion times more massive than the Sun. It is 40 billion kilometers wide.
The photograph confirmed Albert Einstein’s theory, which predicted the existence of black holes more than a century ago.
Difficult words: massive (big), predict (to say what will happen).
What other astronomical phenomena has Einstein's theory helped predict?
