Sagittarius A

This is the first photograph of Sagittarius A* the supermassive black hole at the center of our galaxy. This is the first direct visual evidence of the presence of this black hole. Until now, it has been recognized for its influence on the stars close to it. The black hole was imaged using the Event Horizon Telescope (EHT), an array that joined together eight existing radio observatories around Earth to create one virtual "Earth-sized" telescope. The telescope is named after the event horizon, a nickname for the boundary of the black hole beyond which no light can escape. Credit: EHT Partnership

First image of the black hole at the center of our galaxy Sagittarius A* (Sagittarius Ai Kochav) which until now has been studied for its effect on other stars, this time we can see its event horizon. Photographed by the Ofek Al-Havain partnership which connected eight radio observatories into one radio telescope the size of the Earth
Observations made with the European Southern Observatory's (ESO) Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the center of the Milky Way moves exactly as Einstein predicted in his theory of general relativity. Its orbit is in the shape of a rosette and not in the shape of an ellipse as Newton predicted in his theory of gravity. Figure: ESO
