ROUGH CUT (NO REPORTER NARRATION) An international scientific team on Wednesday announced a milestone in astrophysics - the first-ever photo of a black hole - using a global network of telescopes to gain insight into celestial objects with gravitational fields so strong no matter or light can escape.

The research was conducted by the Event Horizon Telescope (EHT) project, an international collaboration begun in 2012 to try to directly observe the immediate environment of a black hole using a global network of Earth-based telescopes.

The announcement was made in simultaneous news conferences in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo.
