Black Hole.. A Movie Soon

The group of scientists that took the very first image of the black hole in the space, had recently announced that they are planning to capture the first video of the black hole as well.

The video will be a full color one of the hole at the center of a distant galaxy.

According to BBC, the scientists will launch satellites to form a supplement for the current network of eight telescopes to make the movie.

Researchers believe that this network will make them able to see the supermassive black hole.

The challenge comes here for scientists as they are planning of taking a color picture of an object whose gravity is so intense that not even light can escape.

Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the idea of the so-called Event Horizon Telescope (EHT), told BBC News that the next step was to see a black hole in action.

"Just like planets, a black hole rotates. And because of its incredibly strong gravity, it distorts space and time around it. And so seeing this very weird effect of space itself being rotated is one of the holy grails of astrophysics."

Earlier this year, the EHT team published a photograph of a supermassive black hole at the heart of a distant galaxy measuring 40 billion km across - three million times the size of Earth. The image shows superheated gas falling into it in different shades of orange.

According to the scientists, a black hole has no colour of course. But what astronomers can see is the material pouring into it that becomes superheated gas. This gas is thought to change colour as it gets closer to it. Like the Sun when it sets behind clouds in the evening, light from the superheated material will have to travel through more gas on its way to instruments on Earth. So the effect will be to change the colour and appearance of the material around the black hole.
