Now the Dawn spacecraft has returned the best image yet of this cryptic region, after moving into a lower orbit around the planetoid in August. The image makes it clear that one of the spots is centrally located and highly concentrated, while the other appears to be more speckled. That rules out our Death Star hypothesis. Dawn’s chief engineer Marc Rayman says the spacecraft could soon answer our questions about the spots. “Soon, the scientific analysis will reveal the geological and chemical nature of this mysterious and mesmerizing extraterrestrial scenery.”
