In an interview with CNN this Saturday (14), astronomer Catarina Aydar said that the black hole recorded by the international consortium Event Horizon Telescope (EHT) does not pose a risk to planet Earth, even though it is also in the Milky Way.

“He’s the closest to us, but he’s still far away. It is not a risk for people who are here on Earth. The Earth is not directly influenced by it, but, at the same time, it is the closest for us to observe”, he said.

The image of so-called Sagittarius A*, or Sgr A*, captures light deflected by the strong gravity of the black hole, which is 4 million times more massive than the Sun.

“This black hole is actually very far away. So, as much as he is very powerful, has a very strong gravitational energy, he will only influence things that are very close to him”, he explained.

According to the expert, a number of mysteries surround black holes, mainly because the natural characteristics of these objects prevent anything that enters from leaving, including light. Now, one of the great mysteries that scientists are trying to solve “is how these black holes that are at the center of galaxies formed.”
