Hubble observed that galaxies were moving away from each other, indicating that the universe is expanding. He discovered a relationship between a galaxy's distance from Earth and its velocity, known as Hubble's law, providing evidence for this expansion.
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.
The evidence for Hubble's Law, which shows the relationship between distance and recession velocity of galaxies, was collected through observing the redshift of light from galaxies. Astronomers used spectroscopy to measure the redshift of galaxies, which is caused by the Doppler effect as the galaxies move away from us. By studying the redshift of galaxies at different distances, astronomers were able to support the idea that the universe is expanding.
The Hubble telescope has made numerous groundbreaking discoveries, including determining the rate of expansion of the universe, discovering new exoplanets, capturing images of distant galaxies, and providing evidence for the existence of dark matter.
Hubble is a space telescope that has provided stunning images of distant galaxies, nebulae, and other celestial objects. It has helped scientists better understand the universe's age, size, and expansion rate. Hubble has also made important discoveries, such as finding evidence for dark energy and observing distant exoplanets.

Edwin Hubble was famous for measuring the red shift of distant galaxies and interpreting that as evidence of the expansion of the Universe.

Edwin Hubble showed that the red-shift of distant galaxies was as predicted by Georges LeMaitre's hypothesis, which was later named the Big Bang.
