He also developed a diagram to classify galaxies, called his namesake tuning fork.
Albert Einstein denounced the cosmological constant after reading of this man's research. This scientist discovered that all deep space objects not only had a red shift relative to the Earth, but also to each other, a result that suggested an expanding universe. The proportionality between the speed of recession and the distance from the Earth defines this scientist's namesake constant. He also developed a diagram to classify galaxies, called his namesake tuning fork. For 10 points, name this astronomer whose name adorns a space telescope.
