"It does at first appear that an astronomer rapt in abstraction, while he gazes on a star, must feel more exquisite delight than a farmer who is conducting his team."
"Two things [are] more necessary in astronomy than in any other science: patience and organised coöperation. Patience because many of the phenomena develop so slowly that a long time is necessary for them to become measurable, coöperation because the material is too large and too various to be mastered by one man, or even by one institute. And coöperation not only between different workers and institutions all over the world, but also cooperation with predecessors and successors for the solution of problems that require, by their very nature, more than one mans lifetime. The astronomer—each working at his own task...—is always conscious of belonging to a community, whose members, separated in space and time, nevertheless feel joined by a very real tie, almost of kinship. He does not work for himself alone, he is not guided exclusively, and not even in the first place, by his own insight or preferences, his work is always coordinated with that of others as a part of an organised whole. He knows that, whatever his special work may be it is always a link in a chain, which derives its value from the fact that there is another link to the left and one to the right of it. It is the chain that is important, not the separate links."

Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars

"A strange weasel-built creature with a curly tail."
"Although Uranus and Neptune are superficially twin planets, they are different enough to remind us - as do Venus and Earth - that we still have a lot to learn about the mix of natural laws and historical accidents that formed the planets and fashioned their destinies."
"And God made two great lights, great for their use To man, the greater to have rule by day, The less by night, altern."
"L’Astronomie est utile, parce qu’elle nous élève au-dessus de nous-mêmes; elle est utile, parce qu’elle est grande; elle est utile, parce qu’elle est belle… C’est elle qui nous montre combien l’homme est petit par le corps et combien il est grand par l’esprit, puisque cette immensité éclatante où son corps n’est qu’un point obscur, son intelligence peut l’embrasser tout entière et en goûter la silencieuse harmonie."
"And teach me how To name the bigger light, and how the less, That burn by day and night."
