Edwin hubble

#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.

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

We used to think that our own galaxy was the entire universe. Edwin Hubble expanded that understanding to unimaginable distances. Before Hubble, we didn't know about distant galaxies. Telescopes of the time saw only fuzzy areas of what were deemed gas clouds and dust, referred to as nebulae.

Overview The Hubble Space Telescope has given humanity an aperture to the universe for more than three decades. Its discoveries have fundamentally enhanced our understanding of the cosmos. 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 […]

Edwin Hubble

Edwin Powell Hubble was an American astronomer. He profoundly changed astronomers' understanding of the nature of the universe by demonstrating the existence of other galaxies besides the Milky Way. He also discovered that the degree of redshift observed in light coming from a galaxy increased in proportion to the distance of that galaxy from the Milky Way. This became known as Hubble's law, and would help establish that the universe is expanding. Hubble died of a cerebral thrombosis on…
