In July we started receiving audio signals from outside the solar system, and we’ve been studying them since.
Tweets contain sound samples on Soundcloud, data visualisations, and notes about life at the observatory …all generated by code.
ARP is a fictional radio telescope observatory, it’s a Twitter & SoundCloud bot which procedurally generates audio, data-visualisations, and the tweets (and occasionally long-exposure photography) of an astronomer/research scientist who works at ARP, who is obsessive over the audio messages, and who runs the observatory’s Twitter account.
We examine the possibility that Fast Radio Bursts (FRBs) originate from the activity of extragalactic civilizations. Our analysis shows that beams used for powering large light sails could yield parameters that are consistent with FRBs.
I’m guessing Paul Gilster may have thoughts on this.
Churchill, as it turns out, had some pretty solid ideas on SETI.
Churchill was a science enthusiast and advocate, but he also contemplated important scientific questions in the context of human values. Particularly given today’s political landscape, elected leaders should heed Churchill’s example: appoint permanent science advisers and make good use of them.
One might think sending messages to other stars would be a massive, expensive job. No. It isn’t. The Cosmic Call was essentially a crowdfunded hobby project.
We find that the detected signals have exactly the shape of an ETI signal predicted in the previous publication and are therefore in agreement with this hypothesis.
We have made a radio reconnaissance of the star KIC 8462852 whose unusual light curves might possibly be due to planet-scale technology of an extraterrestrial civilization.
Nothing to report yet.
A fascinating guest post by Brian McConnell on Centauri Dreams: what if there’s a galactic equivalent to the internet, allowing civilisations to communicate with a system analogous to packet switching.
Unfortunately this kind of focussed signalling would be hard to detect. But on the other hand, it could explain the Fermi paradox.
The most interesting anomaly uncovered by a Zooniverse project since Hanny’s Voorwerp.
A beautiful bit of design fiction.
A free PDF download from NASA on all things SETI, specifically the challenges of interspecies interstellar communication.
From the cave paintings at Lascaux to the Pioneer plaques and Voyager golden records to Trevor Paglen’s “The Last Pictures” project, Paul Glister examines the passage and preservation of art and information through time. Fascinating.
Or perhaps, as Paglen envisions, those who find a Pioneer Plaque, a Voyager Record, or one of our electromagnetic transmissions will be interested enough to search us out, coming upon a future Earth where all that is left of humanity are our terrestrial ruins and that artificial ring of geosynchronous satellites, with one of them having a particular golden artifact bolted to its pitted hull. In that scenario, about all that would be left for the visiting ETI to do in terms of learning about us would be grand-scale dumpster diving.
This is not only the single most important human endeavour that you can participate in, it is also ridiculously gorgeous.
Re-examining Von Neumann probes, reconciling their apparent scarcity with the Fermi paradox.
A classic (very) short science fiction story that posits an interesting solution to the Fermi paradox.
Would you like SETI to resume sweeping the skies in search of extraterrestrial life? Now you can put your money behind re-kickstarting that noble mission.
A nine-point document that constitutes a "Declaration of Principles Concerning Activities Following the Detection of Extraterrestrial Intelligence."
The search for Dyson spheres.
The title of "most bizarre IE quirk" is hotly contested, given just how many of them there are. But John has found a real humdinger here.
