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.

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.
Interpretation
Pulsars are unique celestial objects that can be identified by their distinct pulsing frequencies.
In this quote, Frank Drake highlights the extraordinary nature of pulsars, fascinating astronomical objects that emit regular pulses of radiation. This distinct characteristic allows for their easy identification across vast distances, suggesting that both humans and potentially other life forms can recognize these celestial signals over extended periods and distances in the cosmos.
In practice
During a lecture on astrophysics, you might quote this to illustrate the uniqueness of pulsars.
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.
While NASA talks about 'Are we alone?' as a number one question, they are putting zero money into searching for intelligent life. There's a big disconnect there.
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.
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.
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.
Genes are not about inevitabilities; they're about potentials and vulnerabilities.
There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.
Species evolve exactly as if they were adapting as best they could to a changing world, and not at all as if they were moving toward a set goal.
I've been so lucky to have done two spacewalks. If you looked at your wristwatch, I was outside about 15 hours, which is about 10 times around the world. And, you know, there's a whole time dilation, distortion thing.
There's a misconception that survival of the fittest means survival of the most aggressive. The adjective 'Darwinian' used to refer to ruthless competition; you used to read that in business journals. But that's not what Darwinian means to a biologist; it's whatever leads to reproductive success.
There are so many intricacies to our brain that won't be understood unless we start to look at the system as a whole. All these different details don't operate in isolation.
