"So numerous are the objects which meet our view in the heavens, that we cannot imagine a point of space where some light would not strike the eye; innumerable stars, thousands of double and multiple systems, clusters in one blaze with their tens of thousands of stars...till, at last, from the limit of our senses, even these thin and airy phantoms vanish in the distance."
On the Connexion of the Physical Sciences by Mary Somerville (1858)
