Famous Astronomers

Astronomy has advanced thanks to the brilliance and curiosity of countless astronomers throughout history. From ancient stargazers to modern astrophysicists, these individuals have pushed the boundaries of our knowledge and inspired generations.

Below were some influental astronomers:

• Galileo Galilei – First to use a telescope for astronomy
• Edwin Hubble – Proved the universe is expanding
• Annie Jump Cannon – Cataloged hundreds of thousands of stars
• Stephen Hawking – Theories on black holes and cosmology

Galileo Galilei was the first to use a telescope for astronomical observations, discovering moons around Jupiter and phases of Venus. Edwin Hubble proved that the universe extends far beyond our Milky Way, and that it is expanding—a discovery that shaped modern cosmology.

Annie Jump Cannon developed the stellar classification system still used today and cataloged hundreds of thousands of stars. Stephen Hawking made groundbreaking contributions to our understanding of black holes and the nature of the universe.

Today, astronomers use powerful telescopes and computers to explore everything from the origins of the universe to the search for life on distant worlds. Their work continues to unravel the mysteries of the cosmos.
