A stunning new preview of a NASA black hole illustrates how gravity distorts our view



  Black World with a Black Hole

When viewed almost from the edge, a turbulent gas disk rotating around a black hole acquires a crazy double appearance. The extraordinary gravity of the black hole changes the paths of light coming from different parts of the disk, creating a distorted image. The extreme gravitational field of the black hole redirects and distorts the light coming from different parts of the disc, but exactly what we see depends on our viewing angle. The biggest distortion occurs when looking at the system almost at the edge. Credit: NASA Goddard Space Flight Center / Jeremy Schnittman

This new visualization of a black hole illustrates how its gravity distorts our gaze, distorting its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole in which the incident matter has gathered into a thin, hot structure called a storage disk. The extreme gravity of the black hole emits light emitted from different parts of the disc, which produces a blurred appearance.

Bright nodes are continuously formed and scattered in the disk as magnetic fields wind and twist through the flowing gas. Closest to the black hole, gas travels around the speed of light, while the outer parts rotate a little more slowly. This difference stretches and cuts the bright knots, creating light and dark canvases in the disc.

Viewed from the side, the disc appears brighter on the left than on the right. The glowing gas on the left side of the disk moves so fast that the effects of Einstein's relativity give it a boost in brightness; the opposite happens on the right side, where the gas that moves away from us becomes slightly darker. This asymmetry disappears when we see the disc right on it, because from this point of view none of the material moves along our line of sight.

Closest to Black Hole, Gravitational Bending so excessive that we can see the underside of the disc as a bright light ring, clearly outlining the black hole. This so-called "photonic ring" is made up of many rings that progressively become paler and thinner, than light that circles the black hole two, three or even more times before it escapes to reach our eyes. Because the black hole modeled in this rendering is spherical, the photon ring looks almost circular and identical from every viewing angle. Inside the photonic ring is the shadow of the black hole, an area that is approximately twice as large as the event horizon – its point of no return.

"Simulations and movies like these really help us visualize what Einstein meant when he said gravity distorts matter of space and time," explains Jeremy Schnittman, who generates these magnificent images using personalized software at the Space Center NASA's Goddard flights to Greenbelt, Maryland. "Until recently, these visualizations were limited to our imagination and computer programs. I never thought it would be possible to see a real black hole. ”However, on April 10, the Horizontal Event Telescope team released its first ever shadow image of a black hole using radio observations on the heart of the M87 Galaxy.
