Black Hole Captured for First-Time: ‘We Have Seen What We Thought Was Unseeable'

"It feels like looking at the gates of hell, the end of space and time," said EHT scientist Heino Falcke

Scientists have unveiled humanity's first-ever photo of a black hole.

The Event Horizon Telescope, a network of eight radio observatories spanning the globe, captured a massive black hole "53.5 million light-years away in galaxy Messier 87," researchers with the National Science Foundation announced Wednesday.

"We have seen what we thought was unseeable," EHT assistant director and Harvard University senior research fellow Sheperd Doeleman said at news conference in Brussels.

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun.

The image of the black hole's event horizon, which is the outer edge of the collapsed star — also known as "the point of no return, which nothing, not even light can escape" — shows a bright ring around a black hole. The ring is formed as light bends in the intense gravity. Doeleman said the black hole is 6.5 billion times bigger than the Sun.

The findings also confirm Albert Einstein's general theory of relativity, said EHT scientist and professor of astronomy and physics at the University of Arizona Dimitrios Psaltis. Einstein predicted that a black hole is so massive and spins so quickly that nothing can break free from its gravitational pull. His theory also stated that this combination of forces creates a shadow in the form of a perfect circle.

Psaltis said their observation "matches the precise predictions of Einstein's general theory of relativity."

The group joined forces in 2006 in an effort to peer into the abyss for the first time. The collaboration of eight different telescopes spanning the globe was aimed to create a "earth-sized" telescope disk in order for researchers to be able to observe black holes, said Daniel Marrone, associate professor of astronomy at the University of Arizona.

In 2017, researchers detected two supermassive black holes: Sagittarius A at the center of the Milky Way and the much bigger one in M87.  While Sagittarius A is much closer to Earth, the black hole in M87 was easier to capture because of its sheer size and the fact that it has less material swirling around it, researchers said.  

Despite its massive size, the black hole is so far away that observing it from more than 50 million light-years away is like "taking a picture of a doughnut placed on the surface of the moon," according Psaltis.

Black holes have long existed in the realm of science fiction and depicted only by illustrations but never actually seen.

This thin disc of rotating material consists of the leftovers of a Sun-like star which was ripped apart by the tidal forces of the black hole. Shocks in the colliding debris as well as heat generated in accretion led to a burst of light, resembling a supernova explosion. (ESO, ESA/Hubble, M. Kornmesser)

"We're looking at a region that we've never looked at before, a region that we cannot really imagine being there," said EHT scientist Heino Falcke. "It feels like looking at the gates of hell, the end of space and time."
