That means the boulder-sized meteorite’s lunar crash could have been visible to anyone on Earth who happened to be staring up at the moon at 8:07 p.m. GMT, weather permitting. “At that moment I realized that I had seen a very rare and extraordinary event,” Jose Madiedo, a professor at the University of Huelva, said in a statement. Madiedo witnessed the collision using two moon-watching telescopes in the south of Spain that are part of the Moon Impacts Detection and Analysis System, or MIDAS observatory. More
