There have been quiet rumblings after a pre-print paper was released on ArXiv from two French-Canadian researchers who interpreted certain sky signal data to be possibly of intelligent extraterrestrial origin. According to their research, it’s not just one star candidate. There are several, all coming from data in the Sloan Digital Sky Survey. These stars experienced rapid bursts of light that, to some researchers, would be the calling card of an intelligent civilization turning on an optical (rather than radio) beacon. There’s something quite tantalizing about the conclusion, “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,” and the paper has been accepted into Publications of the Astronomical Society of the Pacific.
