The interstellar comet 3I/ATLAS carries a chemical clue to conditions in the planetary system of its origin, locked away long before it reached our sun. Its methane signature is unusually rich in heavy hydrogen, suggesting that the comet's frozen ingredients took shape in an intensely cold environment around another star—or in the cloud that preceded it.
What materials did ancient Egyptians use to preserve the dead, and how can their composition still be investigated thousands of years later?
