6 days ago · Edwin Hubble, American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as the leading observational cosmologist of the 20th century.
Aug 12, 2012 · At the time Mount Wilson was the centre of observational astronomy. The 100-inch Hooker Telescope was then the most powerful on Earth. Hubble soon met his greatest scientific rival, Harlow Shapley, who had made his reputation measuring the size of the Milky Way, our own galaxy.
Apr 2, 2014 · Edwin Hubble. Astronomer Edwin Hubble revolutionized the field of astrophysics. His research helped prove that the universe is expanding, and he created a classification system for galaxies...
By studying the light emitted from various galaxies, 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.
Edwin Hubble, for whom the Hubble Space Telescope is named, was one of the leading astronomers of the twentieth century. His discovery in the 1920s that countless galaxies exist beyond our own Milky Way galaxy revolutionized our understanding of the universe and our place within it.
In 1929 he made another startling find - all galaxies seemed to be receding from us with velocities that increased in proportion to their distance from us - a relationship now known as Hubble's Law. This discovery was a tremendous breakthrough for the astronomy of that time as it overturned the conventional view of a static Universe and showed ...
