[NEWS] Three links about interstellar communication: Arecibo, Sonar Festival, Luyten's Star, GJ 273b

• The Arecibo radio observatory of Puerto Rico, famous for (among other things) the first effort at communicating with extraterrestrial civilizations, has been saved from demolition. National Geographic reports.


• Wired looks at how the Sonar music festival got music to be transmitted and eventually decoded by a hypothetical civilization at Luyten's Star, on GJ 273b.


• George Dvorsky at io9 shares convincing arguments that the Luyten's Star transmission is not likely to cause harm--among other things, advanced extraterrestrial civilizations are likely to know we are here. And, hey, if they like our techno, maybe good things can come of this.
