00:00On this day in space.
00:03In 1962, the European Southern Observatory was born.
00:07Happy birthday, European Southern Observatory!
00:10The European Southern Observatory, or ESO, is an intergovernmental research organization
00:14made up of 16 nations that work together to study the southern sky.
00:18Before ESO, all the major ground-based telescopes in the world were in the northern hemisphere.
00:23So ESO built some really big and really awesome telescopes in Chile,
00:27and with these telescopes, scientists have discovered exoplanets like Proxima b,
00:31they've found the oldest star in the Milky Way,
00:33and they've shown that the universe is expanding at an accelerating rate.
00:36And that's what happened on this day in space.
