16 Years of Hubble Data In One Incredible Picture. The Hubble Legacy Field

TL;DR

NASA's Hubble Space Telescope captures 265,000 galaxies in the Hubble Legacy Field image, showcasing galaxy evolution from 13.3 billion years ago.

Transcript

NASA’s Hubble Space Telescope launched on April 24, 1990, and it’s been hard at work ever since, studying the cosmos like no other observatory in human history. Several times in its journey, astronomers have called upon Hubble to study a single spot in the sky for weeks at a time, staring as far as it can, almost to the edge of the observable Unive...
