Definition

Proper noun: * Edwin Powell Hubble: A United States astronomer. He is famous for discovering that the universe is expanding. His observations showed that the speed at which galaxies (then called nebulae) move away from us increases with their distance. This discovery provided key evidence for the Big Bang theory. He lived from 1889 to 1953.

Usage

• Edwin Powell Hubble is used as a proper noun to refer to the historical figure, his work, and his legacy in astronomy.

Advanced Usage

• "Hubble's Law": The astronomical observation that the velocity at which galaxies recede is proportional to their distance. This is a direct result of his work.
  • Astronomy students must understand Hubble's Law and its implications.
• "Hubble constant (H₀)": The unit of measurement in Hubble's Law that describes the rate of expansion of the universe.
