First ever black hole images in the final stage of 'printing — CAS

The nature of one refutes the other.

The telescope uses radio dishes around the world to create an Earth-sized interferometer, which is basically an instrument in which the interference of two beams of light is employed to make precise measurements. Concurrent announcements will be made in Tokyo, Brussels, Taipei, Santiago, and Shanghai. With that, astrophysics will have opened one more tiny crack in the wall of secrets that is the universe. There's a lot riding on what we see on Wednesday, and while we've seen black holes in science fiction for decades, we might be in for a surprise.

Black holes can not be directly observed from the Earth because the black hole's gravity pulls in all approaching light.

The EHT project claims it is an worldwide effort that aims to capture the first-ever image of a black hole.

The US National Science Foundation has scheduled a news conference in Washington to announce a "groundbreaking result from the Event Horizon Telescope (EHT) project", an global partnership formed in 2012 to try to directly observe the immediate environment of a black hole.

An artist's illustration shows Sagittarius A*, the black hole at the center of our Milky Way galaxy. It has a mass equivalent to about 4.1 million of our suns. What a real black hole actually looks like, however, could differ significantly.

One, known as Sagittarius A*, is 26,000 light years away from Earth at the center of our own Milky Way galaxy. Black holes exist from the size of a human cell to more massive than the sun. That allows for an enormous amount of data to be gathered and collated-and over the course of the past two years, it was the collation more than the collection that was the more complicated part. Only when they were done did they regroup and prepare for the April 10 announcement.

Scientists are about to reveal the first image of a black hole and its event horizon-the theoretical boundary that marks the "point of no return".

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

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. However, a black hole that is located within the crowded centre of a galaxy draws matter toward itself. "Usually people think it only swallows something". Theory states that the singularity is permanently hidden from view behind the "event horizon", defined as the radius within which nothing can leave the black hole. Instead they were nearly sucked in, but instead were accelerated by the violent energy in the vicinity of the hole and blasted away.

The EHT is by no means finished with its black hole work. Since then, telescopes in France and Greenland have been added to the network.
