Other light curves - like the one below - show clear patterns. We think that most of the variability is caused by star spots, or pulsations. Having Planet Hunters sort these light curves as variable is an important part of the scientific research that we're trying to do. The Dark Secrets of the Bird World 66 million years ago, a large asteroid about six miles in diameter smashed into what is present-day Mexico. It was the most unpleasant thing you can imagine for everyone here at the time, and it ended up causing the extinction of over 75% of species, including all the dinosaurs. Right? It killed off all the dinosaurs—that’s how the story goes. The thing is, when we picture dinosaurs, we picture large, reptile-looking guys tramping about on land being dicks. But there were also a lot of other kinds of dinosaurs, including some with feathers who could fly. Birds aren’t just the descendants of dinosaurs, they are dinosaurs. Birds are close relatives of the notorious Velociraptor—they share a common ancestor with it from the Jurassic period.
