It’s a telescope essentially as large as the Earth, and it is shedding light on some of the most mysterious phenomena in the universe.

A supermassive black hole churns at the heart of the Milky Way galaxy. To see it clearly, we need a telescope the size of the Earth. But building that is impossible.

So scientists have flipped the problem, and turned the Earth into a telescope.

The Event Horizon Telescope (EHT) is a global array of interconnected radio telescopes that is expected to soon provide humanity’s first glimpse of a black hole. And that’s just one of the many amazing things about it.

Here are some fascinating facts about the world’s most remarkable telescope.

About Perimeter

Perimeter Institute is the world’s largest research hub devoted to theoretical physics. The independent Institute was founded in 1999 to foster breakthroughs in the fundamental understanding of our universe, from the smallest particles to the entire cosmos. Research at Perimeter is motivated by the understanding that fundamental science advances human knowledge and catalyzes innovation, and that today’s theoretical physics is tomorrow’s technology. Located in the Region of Waterloo, the not-for-profit Institute is a unique public-private endeavour, including the Governments of Ontario and Canada, that enables cutting-edge research, trains the next generation of scientific pioneers, and shares the power of physics through award-winning educational outreach and public engagement.
