Certain entities which are lens-shaped or lenticular, appear at the center of a construct named for this scientist.
The deceleration parameter is proportional to the time derivative of a parameter named for this man. That parameter named for this scientist is defined as the time derivative of the scale factor divided by the scale factor. Certain entities which are lens-shaped or lenticular, appear at the center of a construct named for this scientist. A law named for this scientist states that the speed at which certain entities recede from the Earth is equal to their distance from the Earth times a constant named for him. That constant is equal to the reciprocal of the age of the universe. Elliptical and spiral galaxies can be found on his namesake tuning fork diagram. For 10 points, name this American astronomer who lends his name to a telescope that in 1990 was launched into space.
