The Hubble Space Telescope's 'Deep Field' observations are a series of images captured by the telescope over a period of 10 days in 1995. The images were taken of a small and seemingly empty patch of sky, but they revealed thousands of galaxies that were otherwise invisible.
The significance of the 'Deep Field' observations is that they showed us that the universe is much larger and more complex than we had previously thought. Before these observations, astronomers had estimated that there were approximately 100 billion galaxies in the observable universe. The 'Deep Field' observations suggested that the actual number could be much higher, possibly as many as 2 trillion galaxies.
The 'Deep Field' images also revealed that galaxies were much more diverse in shape and size than previously believed. Some galaxies were spiral-shaped, others were irregular, and some were even shaped like rings or tadpoles.
Overall, the 'Deep Field' observations fundamentally changed our understanding of the universe, showing us that it is much larger, more diverse, and more complex than we had ever imagined.

The Hubble Space Telescope's 'Deep Field' observations were a series of images taken in 1995 and 2003 which revealed thousands of galaxies in a small area of space. This deep observation of the universe provided evidence that the universe is much larger and more complex than previously thought, with a wide variety of galaxies and stars. It also showed that the universe is expanding at an accelerating rate, which has led to the development of the theory of dark energy.
The Hubble Space Telescope has made over 1.5 million observations since its launch it 1990, capturing stunning subjects such as Eagle Nebula and producing data that has been featured in almost 18000 scientific articles. But no image has revolutionized the way we understand the universe as much as the Hubble Deep Field.
The Deep Fields gave astronomers the first really clear look back to the time when galaxies were forming. The first deep fields - Hubble Deep Field North and South - gave astronomers a peephole to the ancient Universe for the first time and caused a real revolution in modern astronomy.
Thus astronomers have traced the evolution and formation of galaxies, discovered that most galaxies contain supermassive black holes and mapped the presence of mysterious dark matter that makes up most of the universe's mass and structure.
Taken over the course of 10 days in 1995, the Hubble Deep Field captured roughly 3000 distant galaxies varying in their stages of evolution.
