O how loud
It calls devotion! genuine growth of night!
Devotion! daughter of Astronomy!
An undevout Astronomer is mad.
— Edward Young, 'Night Thoughts.'
Astronomers, like burglars and jazz musicians, operate best at night.
— Miles Kington, 'Welcome to Kington.'
From our home on Earth, we look out into the distances and strive to imagine the sort of world into which we were born. With increasing distance our knowledge fades until at the last dim horizon we search among ghostly errors for landmarks scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be suppressed.
— Edwin P. Hubble, 'Realm of the Nebulae,' 1936
