William Huggins

William Huggins was a 19th-century British astronomer who pioneered the use of spectroscopy to study stars and nebulae. By analyzing the light they emit, he identified their chemical compositions and physical properties, transforming astronomy into a science grounded in physics. His work allowed scientists to understand what distant celestial objects are made of and how they behave, advancing our knowledge of the universe. Huggins is considered a founder of astrophysics, blending astronomy with chemistry and physics to explore the cosmos more deeply.
