Edwin Hubble

Comments Off on Edwin Hubble

1. Edwin Powell Hubble was an American astronomer born on November 19, 1889. He is known for his significant contributions to the field of astronomy.

  1. He discovered the law that bears his name, Hubble’s Law, which states that galaxies are moving away from each other and that their speed of recession increases with distance. This was a major breakthrough in understanding the universe’s expansion.

  2. In addition to Hubble’s Law, he also classified stars based on their spectral classifications as O-B-A-F-G-K-M. This is known as the Hertzsprung-Russell (HR) diagram and helps us understand stellar evolution.

  3. Hubble was an integral part of the Palomar Observatory Sky Survey (POSS), which provided astronomers with the first comprehensive maps of the entire sky, cataloguing millions of stars, galaxies, and nebulae.

  4. The “Hubble constant,” a fundamental parameter used in cosmology to describe the relationship between distance and expansion rate of the universe, is named after him despite it being refined by others since its original formulation in 1929.
