We all know and have heard about the mysterious black hole phenomena. We have known the fact about the black hole and the whole theory on how our planet came into existence. Space is beyond our imaginations, the more we get to know about it, the more mesmeric it gets.

We have come a long way to discovering mind-blowing facts about space, galaxies and the universe. We all have a concept and image of a black hole as a big black dark shadow having galaxies revolving around it. A Black hole is massively powerful, we can only have an idea from the fact that nothing can escape it, even particles and electromagnetic radiation such as light—can’t escape from inside it. Humans only know a little about the Universe.

But with time, technology has evolved. Scientists are claiming to release the first ever real picture of a black hole. A black hole which we have in our minds and imagination of artists and people, as well what’s in the books is going to demolish soon. It’s going to be a historic and important moment in human history.

A new project to examine the supermassive black hole at the center of our galaxy is about to announce the results of its scans. Spotting a black hole is quite hard and more difficult to capture its visual image.

The event horizon telescope is probably trying to take visual of a black hole. And the results will be announced next week.
Instead of a single giant instrument, the Event Horizon Telescope (EHT) is a project connecting dozens of observatories to scan the environment directly around the supermassive black hole at the Center of the Milky Way.

Dr. Paul McNamara, an astrophysicist at the European Space Agency, tells the AFP: “More than 50 years ago, scientists say there was something very bright at the Center of our galaxy.”

This mysteriously bright object was very dense, and had a “gravitational pull strong enough to make stars orbit around it very quickly — as fast as 20 years”, Dr. McNamara added.
Our own solar system takes 230 million years to orbit the Milky Way.

Taking a picture of a black hole is difficult because they don’t emit or reflect any light. So, what are we going to see? “They’re trying to get an image of the black hole’s shadow,” says Avi Loeb at Harvard University

“It’s very different from the shadow cast by an opaque object because a black hole isn’t opaque, it’s absorbing light,” says Loeb. “As a result, we should see a dark inner region surrounded by a sliver of light that looks like a crescent moon.”

That crescent shape is predicted by Albert Einstein’s theory of special relativity, which says that matter moving towards us will look brighter and anything moving away would be dimmed. We may also see the effects of the immense gravity of a black hole, says Loeb, in the form of gravitational lensing which can bend light as it passes nearby.

We will have just a fuzzy picture of two black holes as, if we want to have that much accurate picture we need an EHT sized of our earth.

Still, however, it’s a milestone for our world.  The capability of the human mind is endless.
