20th November 1889

Renowned as one of the most influential astronomers of the 20th century, Edwin Hubble fundamentally transformed our understanding of the cosmos by proving that the universe extends far beyond our own Milky Way galaxy. 

In the 1920s, Hubble's groundbreaking observations revealed that distant celestial objects were actually entirely separate galaxies, vastly expanding the known scale of the universe. He further revolutionised astrophysics by demonstrating that these galaxies are moving away from us at speeds proportional to their distance—a foundational discovery known as Hubble's Law that provided the crucial observational evidence for an expanding universe and laid the groundwork for the Big Bang theory.

Today, his extraordinary legacy continues to drive modern space exploration, most famously immortalised by the Hubble Space Telescope, which continually captures the universe's breathtaking depths. Reflecting on his monumental discoveries serves as a powerful reminder of humanity's enduring quest to comprehend the vast, dynamic cosmos we call home.
