See 1 picture of the black hole in the middle of Milky Way

Consortium Scholars Event Horizon Telescope (EHT), revealed, Thursday morning (12), the first image of a giant black hole in the middle of the Milky Way, the galaxy where the Solar System and, therefore, Earth.

The release of the image of Sagittarius A *, as the black hole is known, is in an international event involving scientists from the EHT and the European Southern Observatory (ESO).

In 2019, the same group of scientists unveiled the first image of a giant black hole. But this has taken place at the center of the galaxy M87, which is 55 million light-years away from our planet.

Sagittarius A * in one 26,000 light-years away from Earth. He studied for many years and his recordings were only possible thanks to the Event Horizont Telescope consortium, which now has 11 telescopes spread across the globe and has observations in eight locations around the world. .

Why does the image of Sagittarius A * look so blurry?

People who often do not respond to the problems that occur around astronomy will find the images released by scientists a little strange, because it has features that are a bit visual.

This is due to the fact that the image is the result of thousands of captures do, with different orientations of the movement of the black hole and the change of light intensity.

As black holes do not emit light, the major challenge in obtaining the shape of them is to capture the “silhouette” caused by the gravitational bending of light in gravity . Therefore, the only way to obtain images of the material in this space is to use a microwave spectrum combined with the power of different observations.

What is a black hole?

In short, the black is product location very heavy with gravity so strong not set up or no problem manage to escape them.

Something that scientists have always thought about in relation to the black hole is the study of the “event horizon” or the indelible point, which makes the region between the center and the inside of the group, once when something enters the area, it becomes impossible. escape.
