Clyde Tombaugh

“I have a feeling that the quest for extraterrestrial intelligence is a one-way street. We are on the receiving end, but not the sending end.”

“I have been to the ends of the solar system.”

“Yes, I was a farm boy, and I did get a C in astronomy in college. But I've been looking at the sky all my life.”

“I estimate the probability of discovering life on another planet in my lifetime is virtually zero.”

“I was just a farm boy from Kansas, but I had a dream. I wanted to see what was out there.”

“It was a moment of high adventure.”

“I really had a tiger by the tail. I couldn't let go.”

“Can you imagine young people nowadays making a telescope?”

“The whole thing was a long, hard, tedious job.”
