Drake, Carl Sagan and Jill Tarter worked diligently to establish a solid scientific footing for SETI, many astronomers remained skeptical or even hostile to the endeavour. This left the space agency gun shy about funding new research. People often think astronomers have carried out exhaustive searches for extraterrestrial intelligence, but nothing could be further from the truth.

For decades, there has essentially been no public money for SETI and only whiffs of private funding. Things, however, are just starting to change — for the best of reasons. New and revolutionary science has transformed our understanding of life and the universe. While the search for intelligence in the universe was being starved to death, something remarkable happened in the study of less advanced forms of life. Beginning in the s, the field of astrobiology — the study of life in its astronomical context — began piling up one revolutionary discovery after another.

From the recognition that Mars was once a very wet planet to the discovery of extremophile bacteria living in the harshest conditions on Earth, astrobiology rewrote our understanding of how life and planets can go together. But the most important element of the astrobiological revolution — and the one most relevant to the study of intelligence and extraterrestrial civilizations — came with the stunning discovery of exoplanets. The question of other planets orbiting other stars is so old that even ancient Greek philosophers beat each other up about it.

Then, in , we answered it when two Swiss astronomers found a Jupiter-sized world orbiting a relatively nearby star. We finally knew we were not alone, at least when it came to planets. Soon, new exoplanets were discovered on a weekly basis, including worlds in the all-important Goldilocks Zone. These were planets with temperatures just right for liquid H2O and, perhaps, life to exist.

By , scientists had found so many exoplanets that they could say with confidence that every star you see at night hosts at least one world. And if you count just five of those stars, one of them will have a planet in the Goldilocks Zone. In the past few years, astrobiologists have moved past simply discovering planets wholesale. Now, the emphasis is to unpack the detailed nature of individual worlds. The process, called atmospheric characterization , means we may be just a few decades away from having real data to argue over about life on distant worlds.

The importance of this possibility cannot be overstated. After thousands of years, and thousands of people just voicing their opinions about life in the universe, in a few decades we may have actual evidence. And because it is science, years will be needed to sort out the implications.

But one way or another, the exoplanet revolution means evidence in the form of carefully collected data is on its way. That is a game-changer, and it demands an end to the skepticism that can still swirl around attempts to think scientifically about extraterrestrial intelligence. To see how this change emerges, you need to first see how atmospheric characterization actually works.

Without the biosphere, the oxygen would quickly react away. With a flotilla of new and more powerful telescopes on the horizon for atmospheric characterization, scientists are now readying themselves by exploring different pathways for the evolution of biospheres on other worlds.

The game now is to find how different forms of alien life can leave imprints — called biosignatures — in the light we catch from those distant worlds. But as these studies deepen, it becomes painfully obvious that staring hard at exoplanets to find biosignatures might just as easily mean we trip over evidence of something more remarkable: technosignatures.

It could be the imprint, in reflected star light, of vast farms of solar energy collectors on a planet. In fact, being smart in science often means preparing for possibilities before you do an experiment or make observations. The workshop brought more than 40 researchers like me together to help NASA map ways a scientific search for technosignatures might be carried out. Advances in artificial intelligence now allow vast amounts of data to be automatically collected, processed and screened for interesting signals.

And the rest of the world is catching on. When the astronomers reported their results and considered all the different explanations a swarm of comets, orbiting clouds of dust, etc. It was a watershed moment, as two professional astronomers were explicitly saying, yes, an exo-civilization should be on the table at this point. And there are still those who claim that any scientist studying exo-civilizations is just in it for the media attention.

But for someone such as Prof. Loeb, the time has passed for fearing the giggle factor in talking about exo-civilizations. He is pushing boundaries because, in his view, we have come too far to not discuss them as a scientific possibility. Astronomer Milan Cirkovic likes to emphasize how the question of other civilizations touches our deepest and most enduring questions about humanity and our place in the universe.

The exoplanet revolution has forced us to see that our world may be just one of many and is perhaps not so different. We are standing on a frontier when it comes to the study of life and the universe. But like all great challenges, the frontier makes demands of us. The question of alien life and civilizations is head-spinningly exciting, but the only way it will be answered is with science. And science, by design, is slow, deliberate and precise. In other words, it can be very boring. So while it is time to abandon the dismissive giggling or pointless hostility over thinking about other intelligent beings in the universe, it is also time for all of us to become savvy consumers of science news.

Whatever discoveries lie ahead, they are going to be thrilling, as they change our view of ourselves and our future. The road ahead will be long and arduous, but that is just as it should be.
