A paperclip-sized probe could probe a black hole's event horizon

A research program proposes launching a nanospacecraft with a light sail, propelled by a laser beam at up to about a third of the speed of light, to reach a nearby black hole within decades and test the theory of relativity under extreme conditions—if one is found.

This is the first image 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. It took five years to process the image. Credit: EHT Partnership

Improving the ability to observe the black hole at the center of the galaxy will make it possible to test Einstein's theory of general relativity

Says Dr. Shahar Hadar, a theoretical astrophysicist from the University of Haifa and Oranim College who also works in the development of the next generation of the Event Horizon Telescope. He also explains why it took five years to produce the photograph

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

Photographing the event horizon of the black hole at the center of the Milky Way is within reach in a few years * The diameter of the black hole that has consumed 4 million suns - barely reaches the orbit of Mercury
