An appreciation of the Hubble’s Deep Field images

posted by Jason Kottke   Mar 03, 2017

More than 20 years ago, the Hubble Space Telescope took a photo of a patch of seemingly dark sky and, lo, it was filled with hundreds and hundreds of galaxies.

About ten years after that, they looked even deeper into the night sky and observed thousands of galaxies, each containing hundreds of billions of stars. The video above is an appreciation of these Deep Field images and what they taught us about the Universe.

In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavour was risky — what, if anything, was going to show up? But what came back was nothing short of spectacular: an image of over 1,500 galaxies glimmering in a tiny sliver of the universe. Alex Hofeldt helps us understand the scale of this image.
