Charles Darwin (1809–1882) was a British scientist whose work on evolution—the way living things change over generations—revolutionized.

Edwin Hubble discovered that other galaxies exist outside the Milky Way. His work led to our current understanding of the expansion of the universe.

This legacy reflects the work of the telescope’s namesake, renowned 20th century astronomer Edwin Powell Hubble. Like the Hubble Space Telescope, Edwin Hubble’s discoveries transformed the frontier […]

#Today In History In 1924, American astronomer Edwin Hubble pointed out that the Andromeda galaxy does not belong to the Milky Way, and there are many galaxies in the universe. He is recognized as the founder of galaxy astronomy and the pioneer of observational cosmology, and is honored as the father of galaxy astronomy by the astronomy community.
