The day of the first published photograph of a black hole – level 1


Messier 87 is a galaxy. It is 55 million light-years away from Earth. Scientists photograph the center of the galaxy. They use eight telescopes. These telescopes are, for example, in Hawaii, Chile, Spain, Mexico, and Antarctica. The scientists see a black hole at the center of the galaxy.

The scientists photograph the black hole in April 2017, but it takes two years to analyze the information from the telescopes.

The scientists publish the first official photograph of a black hole on April 10, 2019.

The black hole is 6.5 billion times bigger than the Sun. It is 40 billion kilometers wide.

One hundred years ago Albert Einstein has a theory about black holes. Now, this theory is true.

Difficult words: telescope (a tool which helps to see things bigger), publish (to make public).

What other predictions did Einstein make about black holes that have since been proven true?
