For 10 points, name this astronomer whose name adorns a space telescope.
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.
