We recently looked at the $100 million infusion into the SETI effort by Yuri Milner, with backing by major figures in the field. When I'm considering SETI developments, I always look to Michael Michaud, whose judicious perspective in his book Contact with Alien...

What It Means to be Human Without Earth: Existential Horror and Hope in Aniara
In the summer of 2018, I took a vacation with my family on an ocean cruise. Being on that cruise ship was very much like being in a small city – minus any vehicles larger than a forklift truck – with just about anything you might want only a stroll away, unless you...
Writing a Social Insect Civilization
Communicating with extraterrestrials isn’t going to be easy, as we’ve learned in science fiction, all the way from John Campbell’s Who Goes There? To Ted Chiang’s Story of Your Life (and the movie Arrival). Indeed, just imagining the kinds of civilizations that might...
On ‘Sun-like’ Stars
The thought of a planet orbiting a Sun-like star began to obsess me as a boy, when I realized how different all the planets in our Solar System were from each other. Clearly there were no civilizations on any planet but our own, at least around the Sun. But if Alpha...
The Ethics of Spreading Life in the Cosmos
We keep trying to extend our reach into the heavens, but the idea of panspermia is that the heavens are actually responsible for us. Which is to say, that at least the precursor materials that allow life to emerge came from elsewhere, and did not originate on Earth....
Pondering Life in an Alien Ocean
No one ever said Europa Clipper would be able to detect life beneath the ice, but as we look at the first imagery from the spacecraft’s star-tracking cameras, it’s helpful to keep the scope of the mission in mind. We’re after some critical information here, such as...
Deep Space Implications for CubeSats
The Hera mission has been dwarfed in press coverage by the recent SpaceX Starship booster retrieval and the launch of Europa Clipper, both successful and significant. But let’s not ignore Hera. Its game plan is to check on the asteroid Dimorphos, which became the...
Advancing Space Technology and Preparing for Contact with Extraterrestrial Intelligence through Multilateralism
Is it possible that we can account for the Fermi paradox by looking to our own behavior as a species? Some science fiction of the 1950s pointed in that direction, as witness The Day the Earth Stood Still (1951). Dr Kelvin F Long addresses the question in terms of the...
Are Interstellar Quantum Communications Possible?
A favorite editor of mine long ago told me never to begin an article with a question, but do I ever listen to her? Sometimes. Today’s lead question, then, is this: Can we expand communications over interstellar distances to include quantum methods? A 2020 paper by...
Set Your Gyros for Mars: Giving a Second Chance to Conquest of Space
Larry Klaes began developing a following for his deep dives into science fiction cinema long ago on Centauri Dreams, through memorable looks at films like The Thing from Another World, Forbidden Planet and The Day the Earth Stood Still. Although he delves into recent...
