J'ai déjà parlé ici de ce que certains appellent la possible "mégastructure" extra-terrestre.
Le mystère autour de ce phénomène ne se dissipe pas, bien au contraire:
By carefully examining all the full-frame images collected during Kepler’s observational campaign, Montet and Simon discovered something astonishing: Not only did the star’s light output occasionally dip by up to 20 percent, its total stellar flux diminished continuously over the course of four years.
(...) “The part that really surprised me was just how rapid and non-linear it was,” Montet told Gizmodo. “We spent a long time trying to convince ourselves this wasn’t real. We just weren’t able to.”
