An international collaboration will allow humans to see a supermassive black hole for the first time. Although we have residual evidence of black holes' existence, such as measurements of the gravitational pull around the holes, we've never been able to see these invisible entities. Thanks to this ongoing project, we soon will.

Scientists believe that black holes exist at the center of every galaxy. Our galaxy’s black hole is called Sagittarius A, and lurks within the Sagittarius constellation, NASA reports. Starting in April 2017, a team of international researchers linked telescopes around the globe, aiming them simultaneously at Sagittarius A, the National Radio Astronomy Observatory reported. This black hole is about 26,000 light years away from Earth and has a mass equal to 4 million suns.
