How the Event Horizon Telescope took first ever image of a black hole

The video explains the challenges of capturing an image of a black hole, which is difficult due to its nature of not allowing light to escape and its small size from an astronomical perspective. To overcome this, scientists connected radio dishes globally, creating a virtual telescope the size of Earth. This international effort involved hundreds of researchers and significant data storage. The result was the first direct visual evidence of a supermassive black hole, showcasing the power of global collaboration and technological innovation.

Why are black holes difficult to capture in images?

• Light cannot escape their gravity.

• They move too quickly across the sky.

• They are too large to fit in a telescope's view.

• They emit too much light.

What was the key innovation in capturing the image of a black hole?

• Using a single powerful telescope.

• Connecting radio dishes globally.

• Capturing images from space.

• Using infrared technology.
