How much of the universe is hidden in a single sliver of sky?

How small are we in the scale of the universe? - Alex Hofeldt · 4:08 · Video: TED-Ed · Watch at the source

In short: In 1995, astronomers took a massive risk by pointing the Hubble Telescope at what appeared to be empty space. This video explores the staggering scale of what they discovered: a tiny patch of sky teeming with thousands of galaxies.

The video examines the profound implications of the Hubble Deep Field, an observation conducted in 1995. By directing the Hubble Telescope toward a seemingly vacant area near the Big Dipper, scientists uncovered a universe far more crowded than previously imagined.

The resulting image revealed over 1,500 galaxies glimmering within a remarkably small section of the cosmos, fundamentally shifting our understanding of the vastness and density of the universe.
