Edwin Powell Hubble Cop Quotations

The great spirals... apparently lie outside our stellar system.

There we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial.

The history of astronomy is a history of receding horizons.

Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive to the entire electromagnetic spectrum - we explore the universe around us and call the adventure science.
