# Arthur Auwers: The Meticulous Star Mapper Who Built Celestial GPS

0:00Hi, this is Alex Cantrowitz. I'm the host of Big Technology podcast, a long time reporter and an on-air contributor to CNBC. And if you're like me, you're trying to figure out how artificial intelligence is changing the business world and our lives. So each week on Big Technology, I bring on key actors from companies building AI tech and outsiders trying to influence it, asking where this is all going. They come from places like Nvidia, Microsoft, Amazon, and plenty more. So if you want to be smart with your wallet, your career choices, and meetings with your colleagues and at dinner parties, listen to Big Technology podcast wherever you get your podcasts. Hey, I'm Josh Spiegel, host of the podcast, Lunatic in the newsroom. If you enjoy journalism that drifts into mild panic, wild overthinking, and a guaranteed nervous breakdown, Lunatic in the newsroom is for you. It's news like you've never heard before. The only newsroom with a panic button, you'll laugh, you'll cry, and gasp and horror as the show spirals completely out of control. It's not just news, it's emotionally unstable. Lunatic in the newsroom,

1:02listen today. Number Astronomy to Night Podcast. This is your Astronomy to Night Podcast. Welcome Star Grazes. Today, March 23rd marks a truly fascinating date in astronomical history. On this very date in 1882, the German astronomer Arthur Hours made one of the most painstaking contributions to astronomy. You've probably never heard of, but trust me, you've benefited from it countless times. You see, Hours was obsessed, and I mean obsessed, with creating the most accurate star catalogue the world had ever seen. While other astronomers were out there discovering flashy, unabulating comets, Hours was meticulously measuring the positions of thousands upon thousands of stars with the precision of someone checking their work on a final exam multiple times. On March 23rd 1882, he published monumental revisions to the fundamental catalogue, which became the backbone for virtually all celestial navigation and coordinate systems for

Every telescope pointed at the sky for the next century was essentially using Arthur Hours coordinates. It's a perfect reminder that astronomy isn't always about the most dramatic discoveries, sometimes the real heroes of the meticulous record keepers who build the infrastructure that makes everything else possible.
