How a Single Image Taken in 1995 Revolutionized Astronomy

The Hubble Space Telescope has been one of the most important scientific instruments to have ever been deployed, and it has provided countless advancements to the fields of astronomy and cosmology. This fascinating video takes a look at one of the earliest and most important images the telescope took and how it continues to impact science even 25 years later.

Coming to you from Vox, this excellent video details the 1995 Hubble Space Telescope deep field observation and how it vastly changed our knowledge of the universe and even how astronomers work with data. The two things I have always loved about these images are the age of the light we are looking at and the sheer vastness contained in such a tiny spec (relatively speaking) of space. The image shows some galaxies that are over 12 billion years old, meaning they were around at a relatively young time for the universe, giving us amazing insight into its history. It also boggles my mind just how much is contained in each of those little blips of light. Entire galaxies with millions or billions of stars reside in those seemingly innocuous specs, reinforcing how the universe operates on scales of size that are truly beyond our own intuitive grasp. Check out the video above for the full story.
