Scientists have seen light from behind a black hole for the first time ever. The astronomers' discovery proves Einstein's predictions right over a century later.

An animation of how light rays can be gravitationally bent to form a photon sphere. A photon sphere [1] or photon circle [2] arises in a neighbourhood of the event horizon of a black hole where gravity is so strong that emitted photons will not just bend around the black hole but also return to the point where they were emitted from and consequently display boomerang-like properties.

An echo of ShaSS 073 galaxy's light detected by ESO's VLT Survey Telescope. The ShaSS 622-073 system is composed of the larger galaxy ShaSS 073 (seen in yellow in the image on the right) and the smaller galaxy ShaSS 622 (seen in blue) that are at the very beginning of a merger.
It is only restricted by the speed of light. Closer to the black hole spacetime starts to deform. In some convenient coordinate systems, there are more paths going towards the black hole than paths moving away. [Note 1] Inside the event horizon all future time paths bring the particle closer to the center of the black hole.
The black hole duo is the closest pair found through visible and X-ray light. While other black hole pairs have been observed before, they are usually much farther apart.
A view of M87* black hole in polarised light Sagittarius A*, black hole in the center of the Milky Way. The Event Horizon Telescope (EHT) is an active program that directly observes the immediate environment of black holes' event horizons, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observing the black hole ...
