Quote by Harlow Shapley

"We are made of star-stuff. We are a way for the cosmos to know itself."

"The universe is a vast and awesome place. We are incredibly fortunate to have the opportunity to study it."

"Our galaxy is but one of millions. Humility before the cosmos is the beginning of wisdom."

"We must never stop asking questions about our place in the universe."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
