Born on November 20, 1889 in Marshfield, Missouri, Hubble spent his youth honing athletic skills in basketball, football, baseball, track, and boxing, while mentally feeding his curiosity through science fiction novels.He entered the University of Chicago in 1906 as an undergraduate, earning a bachelor’s degree in mathematics and astronomy.He briefly deviated from his path of exploration, largely fueled by his father’s expectations, to study law at Oxford University as a Rhodes Scholar. But his deep longing to pursue a career in the sciences outweighed his father’s visions, and Hubble switched gears and obtained a Ph.D. in astronomy from the University of Chicago in 1914, setting his focus on the heavens.Destined for the cosmos, Hubble’s journey led him to Mount Wilson Observatory in California and the 100-inch Hooker Telescope, the world’s largest at the time. Hubble used the 100-inch telescope to observe faint, fuzzy, cloud-like patches of light broadly labeled nebulae. Up until the early 20th century, our perception of the cosmos fell within the bounds of the Milky Way. Although astronomers speculated about the existence of other galaxies in our universe, they had no observable evidence of them. It wasn’t until Hubble pointed the Hooker Telescope at the constellation Andromeda that our perspective shifted.Hubble studied what was then known as the Andromeda Nebula, an object that for centuries appeared as an elongated cloud of light. In 1923, he resolved individual stars in this “nebula.”

Hubble’s continued observations of Andromeda resulted in one of the most transformative discoveries in cosmology. He uncovered his first Cepheid variable star, a type of star used to measure distances in space by how it changes brightness. A Cepheid variable star’s intrinsic brightness is directly related to its cycle from bright to dim and back to bright again. By charting the changes in these stars, Hubble discovered that Cepheid variable stars in Andromeda were much farther away than those in the Milky Way. This contrast in distance led Hubble to believe the Andromeda Nebula was a galaxy in its own right. Hubble used this technique to study other so called “nebulae” in the universe, and concluded that millions of galaxies existed beyond our own.Hubble devised what is now the most influential system for classifying them: the Hubble Classification Scheme. This method of classifying galaxies arranges them in two main categories based on their shapes – elliptical or spiral – and is subdivided based on specific characteristics of each galaxy.By 1929, Hubble had completely reimagined our place in the universe; not only was it home to millions of other galaxies, but the universe itself was expanding as well.Hubble discovered that the light appeared displaced toward the red end of the spectrum. It became apparent that our universe was ceaselessly expanding outward, and all galaxies housed within it were moving away from one another. This phenomenon, known as redshift, reveals that the farther a galaxy is away from us, the redder its light will appear. Hubble also demonstrated that galaxies farther away from us are receding faster than those nearby – a fundamental observation now known as Hubble’s Law.From one man’s glimpse into the heavens to humanity’s universal quest to understand the unknown, Edwin Hubble’s contributions to cosmology have pushed humanity to the ultimate edge of the cosmic frontier. Today, the Hubble Space Telescope carries his name and enduring legacy with pride, as it searches for the questions we have yet to ask and the answers still waiting discovery.
