SETI is a mirror, a mirror that can show ourselves from an extraordinary perspective and can help to trivialize the differences among us.

We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.

We misuse language and talk about the 'ascent' of man. We understand the scientific basis for the interrelatedness of life, but our ego hasn't caught up yet.

Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.

We are the laws of chemistry and physics as they have played out here on Earth, and we are now learning that planets are as common as stars. Most stars, as it turns out now, will have planets.

We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star.

The existence of life beyond Earth is an ancient human concern. Over the years, however, attempts to understand humanity's place in the cosmos through science often got hijacked by wishful thinking or fabricated tales.

In the future, will our technologies help stabilise or planet and population, leading to a very long lifetime for us? Or will we destroy our world and its inhabitants, after only a brief appearance on the cosmic stage?

Our television transmitters leak out from the Earth. And actually, there's a sphere surrounding the Earth from the earliest television signals, maybe 70 years ago, that's going out one light year per year. But it's really weak.

As I was leaving graduate school in 1974, I was recruited to join a fledgling SETI project at the Hat Creek Observatory in California, mainly because I knew how to program an ancient PDP8/S computer that had been donated to the project.

I can actually build my equipment at the back end of the telescope such that it takes the data from all of the separate antennas and adds the signal together with different time delays and different phase shifts - it's as if I were picking out up to eight individual pixels in this large field of view.

Life has evolved to thrive in environments that are extreme only by our limited human standards: in the boiling battery acid of Yellowstone hot springs, in the cracks of permanent ice sheets, in the cooling waters of nuclear reactors, miles beneath the Earth's crust, in pure salt crystals, and inside the rocks of the dry valleys of Antarctica.

The space that we're looking through is nine-dimensional. If you build a mathematical model, the amount of searching that we've done in 50 years is equivalent to scooping one 8-ounce glass out of the Earth's ocean, looking and seeing if you caught a fish. No, no fish in that glass? Well, I don't think you're going to conclude that there are no fish in the ocean. You just haven't searched very well yet. That's where we are.

Might it be the discovery of a distant civilization and our common cosmic origins that finally drives home the message of the bond among all humans. Whether we're born in San Francisco or Sudan or close to the heart of the Milky Way Galaxy, we are the products of a billion-year lineage of wandering stardust. We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.
