First close up picture of a Black Hole (Conspiracy / Strange)

It's all lies, not even a real image. It's a computer generated mock up of what they think it looks like from the data they created :-jack the picture is useless it means nothing.


Is this an actual photograph?

No, not in the traditional sense. "It is difficult to make an image with radio waves," Crew said. The mission scientists measured radio waves being emitted from the black hole's event horizon :-roll and then processed that information with a computer to make the image that you see.


How did scientists capture this image?

Over 200 astronomers around the world took the measurements using eight ground-based radio telescopes collectively known as the Event Horizon Telescope (EHT). These telescopes are typically located at high-altitude sites such as volcanoes in Hawaii and Mexico, mountains in Arizona and the Spanish Sierra Nevada, the Atacama Desert and Antarctica, according to a statement from the National Science Foundation.

In April 2017, the astronomers synchronized all the telescopes to take measurements of radio waves being emitted from the event horizon of the black hole, all at the same time. Synchronizing the telescopes was akin to creating an Earth-size telescope with an impressive resolution of 20 microarcseconds — enough to read a newspaper in the hands of a New Yorker all the way from a cafe in Paris, according to the statement. (In comparison, the black hole they imaged is about 42 microarcseconds across).

They then took all these raw measurements, analyzed them and combined them into the image that you see.
