That is a collection of micrometeorites found in Antarctica, featured in the 2020 book Atlas of Micrometeorites.
Every year, roughly 10 particles of space dust land on each square meter of Earth’s surface.
That means that they are everywhere. They are on the streets. They are in your home. You may even have some cosmic dust on your clothe.
Round and multicolored like tiny marbles, micrometeorites are as distinctive as they are ubiquitous, yet they escaped notice until the 1870s, when the HMS Challenger expedition dredged some up from the bottom of the Pacific Ocean.

Holography is the photographic process of recording light that is scattered by an object, and presenting it in a three-dimensional way. Invented in the early 1950s by the Hungarian-British physicist Dennis Gabor, the discovery later earned him the Nobel Prize in Physics in 1971.
