Earthlings have never seen a black hole - but that could change tomorrow

At the Event Horizon Astrophysicists Set to Reveal First

First results from the project, known as the Event Horizon Telescope, are being unveiled at 9 a.m. ET (6 a.m. PT) Wednesday during a global wave of briefings. He said that imaging the Milky Way's black hole is just as hard as spotting an orange on the surface of the moon.

The image of Sagittarius A, the black hole at the center of our Milky Way galaxy, is set to be released tomorrow.

But how can telescopes capture the image of a Black Hole when as its concept implies it is nothing but a black hole?

He and his colleagues are acting as if they have something to celebrate.

The EHTC press release said it will present its first results in multiple simultaneous press conferences around the world.

Six media events around the world will be held simultaneously in Washington, D.C, Brussels, Santiago, Shanghai, Taipei and Tokyo. The team and their friends have booked the National Air and Space Museum for a party that evening.

Countless theories, calculations, and estimations have been made about black holes, leading science to suspect a jet black "pit" of sorts with gravitational pull so intense that nothing can escape it. This includes the director of the EHT project, Shepherd Doeleman, from the Harvard-Smithsonian Center for Astrophysics, Daniel Marrone, an astronomer with the University of Arizona, Avery Broderick, from the University of Waterloo in Canada, and Sera Markoff, of the University of Amsterdam, Netherlands.

A black hole's event horizon, one of the most violent places in the universe, is the point of no return beyond which anything - stars, planets, gas, dust, all forms of electromagnetic radiation including light - gets sucked in irretrievably. The vague idea of a black hole - meaning, a singularity so dense and so massive that its escape velocity is greater than the speed of light - was first theorized by English scientist John Michell in the 18th century, and later developed further by Albert Einstein in the 20th century in his General Theory of Relativity.

Much of the speculation says Wednesday's news will be about Sagittarius A*.

Astronomers have, however, been able to observe the effects a black hole has on the stars and cosmic gas clouds surrounding it.

Since 2017, the Event Horizon Telescope Collaboration (EHT) has been studying two supermassive black holes, one located at the center of the Milky Way, called Sagittarius A*, the other found at the core of the supergiant elliptical galaxy Messier 87.

And the black hole is only located about 26,000 light-years away from Earth - a distance of 152,844,260,000,000,000 miles (245,978,990,000,000,000km).

Photos of black holes have been elusive for a number of reasons.

Psaltis described a black hole as "an extreme warp in spacetime", a term referring to the three dimensions of space and the one dimension of time joined into a single four-dimensional continuum.
