Scientists say that a meteorite that crashed into Earth 40 years ago contains millions of different carbon-containing, or organic, molecules.
Although they are not a sign of life, such organic compounds are life’s building blocks, and are a sign of conditions in the early Solar System.
It is thought the Murchison meteorite could even be older than the Sun.
The results of the meteorite study are published in the Proceedings of the National Academy of Sciences.
