Citizen Astronomy FTW

The video discusses the popular theory of the moon's formation, which suggests a Mars-sized impactor collided with Earth, forming the moon. Recent research challenges this theory, finding similar tungsten concentrations in both Earth and moon rocks, suggesting alternative explanations. The video also highlights a citizen science project, Snapshot Supernova, where volunteers helped identify new supernovae using data from the Sky Mapper telescope, demonstrating the power of human collaboration in scientific discovery.
