Black holes, dark matter, dark energy, antimatter and many other unimaginable scientific discoveries and theories have been made with the Hubble telescope. With its help, humanity has seen the most distant galaxies, located millions of light years away from us.
Although these phenomena have always existed, people learned about them only thanks to a special instrument, invented it and sent it into space.

Hubble changed the perception of the World, and it ceased to be the same.
