CSI: LMC

This is what the scene of the crime looks like. The apparent collision may simply be an illusion - don't be fooled. But what we've got here are two dead stars, but no bodies - at least none we've found. But by comparing an optical image (shown in purple) with a Chandra X-ray image (in green and red), forensic astronomers found clues to the identities of the corpses. The lower one had an iron deficiency - probably an overweight star who never ate right and died too young. In contrast the one on the upper left had plenty of iron - probably a lightweight who would've lived to a ripe old age if not for a treacherous neighbor. Motives are hard to discern, but when you live in a violent place like the LMC, who needs a motive?
