Horizon - How BIG is the Universe?

Mapping the universe is a job for pioneers. Nick Risinger is blazing a trail through the American Southwest.

Nick Risinger "You have to be pretty persistent. No stopping. You've got to keep going."

Nick wants to put our entire galaxy on the map. He's on a single-handed mission, to photograph the Milky Way.

Nick Risinger "New Mexico is a great place to take photos. It's dry, it's high, and there's not a whole lot of city around here. There's a break in the weather and you get a full, almost a full night in. Other times, you only get, you know, 10% of the night. But it's all luck of the draw."

In the modern world, few of us have skies dark enough to see the Milky Way. But Nick plans to show us our home galaxy like we've never seen it before.

Nick Risinger "I'm trying to give people that broad, big-picture understanding of the entire night sky, and where they fit into that."

Our galaxy has nearly half a trillion stars. Most of them are too dim and distant to see. But Nick's cameras are more than 2000 times more sensitive than the naked eye.

Nick Risinger "If I had known how much work it would be going into it, I probably wouldn't have even started. But my personality is, once you start something, you finish it."

After two years, he's photographed 20 million stars… By stitching together more than 37,000 separate images.

Nick Risinger "Some people might be driven crazy by hearing shutters clack all night long. But it is actually music to my ears, because it means they are working."

By combining data from six different cameras, he's captured something that would tax even the world's most powerful telescopes. His final image is the highest definition, full colour map ever made of the Milky Way.

But he hasn't just mapped it… He's made a hand-held gate to the Galaxy.

Nick Risinger "This is like a window to the sky. And you can point it in any direction and be shown exactly what you're looking at. So here, we're looking at the centre of our galaxy. This is our Milky Way. You can see this bright cluster of many small stars."

The map reveals more features with every level of detail.

Nick "As we zoom in here to the centre of the galaxy, I'll point out this dark patch here, this is the Pipe nebula, and it's one of my favourite landmarks to help me orient myself."

But it's the sheer size of the image that reveals its true ambition. From one side to the other, it's 100,000 light years.

Nick "This image is such a big subject, and it makes you feel so small. 100,000 light years! It boggles the mind just trying to comprehend just how vast that is."

But the fact is, the map of the universe has barely begun.
