There's a black hole announcement coming this week, and it'll be a big one. It's coming from the Event Horizon Telescope, a global network of telescopes that has been working for 13 years to bring us the very first photo of a black hole.

This is a HUGE undertaking. Black holes are among the most elusive objects in the Universe. They have such intense gravity, not even electromagnetic radiation - light, radio waves, X-rays, etc. - can travel fast enough to achieve escape velocity.

That 'point of no return' is called the event horizon.
