That most galaxies move away from us; and that the general tendency is that galaxies that are farther away move away from us faster.
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.

Edwin Hubble noticed that galaxies are moving away from us in all directions. This observation led to the conclusion that the universe is expanding, which is now known as Hubble's Law.

Since the Hubble Telescope is in space, it avoids interference from the atmosphere.
The Hubble Space Telescope provides valuable insights into the universe by capturing high-resolution images of celestial objects like planets, stars, and galaxies. It helps astronomers study the origins of the universe, track the movement of celestial bodies, and explore the evolution of galaxies. Additionally, Hubble facilitates the discovery and observation of astronomical phenomena, deepening our understanding of the cosmos.
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
HST's observation time and instruments are managed by the Space Telescope Science Institute at Johns Hopkins University in Maryland.
Anyone can request observation time on HST - in the past, the Hubble Director has opened up his own time for use by amateur astronomers. Competition for time is fierce though, and is generally given to academics and scientists, though "targets of viewing opportunity" are considered if it falls within mission parameters. Anyone can download the thousands of photos taken by the Hubble, at hubblesite.org.

The Hubble Space Telescope was named after the American astronomer Edwin Hubble, who played a crucial role in changing our understanding of the universe by demonstrating that galaxies are moving away from each other.
