The history of astronomy is a history of receding horizons.

Wisdom cannot be directly transmitted, and does not readily accumulate through the ages.

A scientist naturally and inevitably ... mulls over the data and guesses at a solution. He proceeds to testing of the guess…

Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.

The great spirals, with their enormous radial velocities and insensible proper motions, apparently lie outside our Solar system.

Observation always involves theory.

Science is the one human activity that is truly progressive. The body of positive knowledge is transmitted from generation to generation.

Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and…

With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary-the utmost limits of our telescopes. There, we…

I knew that even if I were second or third rate, it was astronomy that mattered.

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

Astronomy is something like the ministry. No one should go into it without a call. I got that unmistakable call, and I…

Equipped with his five senses, man explores the universe around him and calls the adventure Science.

All nature is a vast symbolism: Every material fact has sheathed within it a spiritual truth.

Past time is finite, future time is infinite.

— Edwin Powell Hubble

At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will…

The outstanding feature, however, is the possibility that the velocity-distance relation may represent the de Sitter effect, and hence that numerical data…
