The problem with trying to take a picture of a black hole is that it consumes everything, even the light around it. Now, a team of scientists is working to make the first image of a black hole by using telescopes around the world to look at its shadowy edge.
Called BlackHoleCam, the project recently received a Synergy Grant from the European Research Council for 14 million (a little over $19 million). In a statement, Heino Falcke, a radio astronomy professor at Radboud University Nijmegen in the Netherlands and one of the three BlackHoleCam principal investigators, explained:
While most astrophysicists believe black holes exist, nobody has actually ever seen one. The technology is now advanced enough that we can actually image black holes and check if they truly exist as predicted: If there is no event horizon, there are no black holes.
The event horizon is that edge where everything turns to nothing (although, based on the hallucinatory events of the 1997 sci-fi horror film of the same name, you REALLY dont want to see whats out there). The theory is that theres a supermassive black hole right at the center of our beloved Milky Way galaxy, and this is the one the BlackHoleCam is aiming to photograph. Its not quite a photograph in the traditional sense one hurdle being, of course, that photographs are all about capturing light, and black holes are sort of the least photogenic things in our universe in that regard. The image would rely on a whole team of telescopes around the world (including the fancy new ALMA observatory in Chile), with their data synthesized by supercomputers. Or, as Space.com writes in their coverage: This method can, in effect, create a virtual telescope the size of the entire Earth. Awesome!
