Photo of black hole. How Scientists Captured the First Image of a Black Hole

Historic First Images of a Black Hole Show Einstein Was Right (Again)

. Trying to take an image of that from the 26,000 light year distance at which the Earth sits from the center of the Milky Way is like trying to spot an orange on the surface of the moon—with the naked eye. Scientists are also curious about the mechanism by which some supermassive black holes traveling at near light-speed. True to the nature of the science, the picture does not show the black hole itself. With time they they emit enormous amounts of energy.

The larger the diameter, or aperture, of the telescope, the greater its ability to gather more light and the higher its resolution or ability to image fine details. Three new telescopes are being brought online—in Greenland, France and another in Arizona—and a second observing run was already conducted in April 2018. Although the famed physicist was skeptical that black holes even existed, solutions to his equations for the general theory of relativity, which he , predicted that if the extra-massive objects populated the universe, they should be spherical, resembling a dark shadow embedded in a ring of light. The National Science Foundation and agencies in East Asia then joined in to bankroll the project to the tune of more than £40m. A team of 200 scientists pointed the networked telescopes towards M87 and scanned its heart over a period of 10 days.

Gathering data for four days around the world gave the team a substantial amount of data to process. Problematically, though, that mass estimate is much larger than the number derived from the motion of orbiting gas, which is the easier, more commonly used technique when trying to weigh a black hole. At the time, no-one thought it was possible. The crescent of light comes from luminous gases, heated to hundreds of billions of degrees, that orbit just outside the black hole, tracing the region just beyond the event horizon. It then took two years for scientists to assemble the mugshot. Click the link to confirm your subscription and begin receiving our newsletters.

Before the team could begin collecting data, they had to find a time when the weather was likely to be conducive to telescope viewing at every location. With only five nights available during the observing window, Fish and his colleagues met daily to make the nerve-wracking decision whether to activate the network, juggling information about current weather conditions at each site and how those conditions might change over the coming days. In the end, six observatories in Mexico, Hawaii, Arizona, Chile, and Spain aimed their eyes into sky and stared at M87, which is the biggest galaxy in the center of the Virgo cluster. Comparing and combining the radio waves must be done with extraordinary care, so that critical information about the size and structure of the event horizon is not lost when they are added together. Then, because combining observations from different observatories is no simple task, four teams processed the data independently, using different algorithms and testing it against different models.

In the popular imagination, it was thought that capturing an image of a black hole was impossible because an image of something from which no light can escape would appear completely black. Further, the event horizon should be roughly circular and of a predictable size, which depends on the black hole's mass. For a parallel light ray not be drawn into the object it must be 2. What astronomers hope to finally see when they add up all the signals is a halo of light surrounding a dark circle—the shadow of the black hole. Locking down an image of M87's supermassive black hole at such distance is comparable to photographing a pebble on the Moon, the scientists said. The data also offer some hints about how some supermassive black holes manage to unleash gargantuan jets of particles traveling at near light-speed.

For your security, we've sent a confirmation email to the address you entered. But this time, it's the real deal. They have exotic properties and are mysterious to us. The great distances between this collection of installations, known as the Event Horizon Telescope array, actually increases their effectiveness. Even more intriguing is the question of what happens when an object falls into a black hole.
