Tiny Sky Patch Reveals a Universe of Galaxies, Thanks to Hubble
TL;DR Summary
In December 1995, the Hubble Space Telescope spent ten days staring at a tiny, seemingly empty patch near the Big Dipper to avoid foreground clutter. The resulting Hubble Deep Field exposed about 3,000 galaxies in that minute patch, turning emptiness into a crowded view of the cosmos and shaping our understanding of galaxy formation and the scale of the universe.
- In 1995, astronomers aimed the Hubble Space Telescope at a tiny patch of sky that looked almost empty — a dark spot near the Big Dipper no wider than a pinhead held at arm’s length. After 10 days of exposures, the darkness resolved into roughly 3,000 gala Space Daily
