last April, an international consortium of astronomers made public the first photo of the shadow of a black hole. In the historic image, we saw the irregular outline of a monster supermassive located in the galaxy Messier 87, at 55 million light-years from Earth. The obtaining of the snapshot, although blurred, it required a work immense, and it was a technological advance unprecedented. Probably, astronomers will be able to provide better images in the next few years and perhaps look to the new simulation done by NASA.

The black holes are distinguished by a gravitational field so strong that nothing, not even light, manages to escape from them. The matter that falls accumulates in a structure, slim and horny-called accretion disk. The spectacular display of the u.s. space agency illustrates how the brutal severity of these wells cosmic distorts our view, deforming its environment as if it were a mirror of fair.

The gravitational field far from the black hole redirects and distorts the light coming from different parts of the disk, but exactly what we see depends on our angle of vision. The greatest distortion occurs when viewing the system nearly horizontally. Seen from the side, the disk looks brighter on the left than on the right.

The prediction of Einstein

closer to the black hole, we can see the bottom of the disk as a ring of bright light. Is the so-called "ring photon"), consisting of multiple rings that become progressively more weak and thin, from the light that has surrounded the black hole, two, three or even more times before escape to reach our eyes. Because the black hole is modeled in this display is spherical, the ring of photons is seen almost circular and identical from any angle of vision. Within the ring of photons is the shadow of the black hole, an area approximately twice the size of the event horizon, their point of no return.

"simulations and films such as these really help us to visualize what Einstein meant when he said that gravity warps the fabric of space and time ", says Jeremy Schnittman, who generated the images using a custom software at the Goddard Space Flight Center of NASA in Greenbelt, Maryland. "Until very recently, these visualizations are limited to our imagination and computer programs. I never thought that it would be possible to see a black hole in real", he says in reference to the photo of the heart of M87.
