#Constellation.js

We had the sky up there, and we used to lay on our backs and look up at them, and discuss whether they was made or just happened. 
— Mark Twain

The contemplation of celestial things will make a man both speak and think more sublimely and magnificently when he descends to human affairs. 
— Cicero
