Other intelligent life-forms will differ greatly in appearance - they may resemble the creature in E.T. or startle us with their beauty - but life itself is common, I'm certain.

We send messages all the time, free of charge. There's a big shell out there now, 80 light-years around us. A civilization only a little more advanced than we are can pick those things up.
Interpretation
What this quote means
The quote conveys the idea that our communications are constantly reaching beyond our planet into the cosmos, potentially to be picked up by other civilizations.
Frank Drake suggests that humanity's communications, which we often take for granted and send freely, have the potential to travel vast distances in space. This 'big shell' he refers to represents an area around Earth where signals emitted could be detected by other civilizations that are only slightly more advanced than ours, raising the possibility of interaction with extraterrestrial intelligences.

Forty years as an astronomer have not quelled my enthusiasm for lying outside after dark, staring up at the stars. It isn't only the beauty of the night sky that thrills me. It's the sense I have that some of those points of light are the home stars of beings not so different from us, daily cares and all, who look across space with wonder, just as we do.

There was a magic about pulsars... no other things in the sky had such labels on them. Each one had its own distinct pulsing frequency, so it could be identified by anybody, including other creatures, after a long period of time and far, far away.

Right now, there could well be messages from the stars flying right through this room. Through you and me. And if we had the right receiver set up properly, we could detect them. I still get chills thinking about it.
