High-molecular-weight organic matter in the particles of comet 67P/Churyumov–Gerasimenko

The COSIMA mass spectrometer on the Rosetta spacecraft has analysed the solid organic matter found in dust particles emitted by comet 67P/Churyumov–Gerasimenko; this matter is similar to the insoluble organic matter extracted from carbonaceous chondrites such as the Murchison meteorite, but is perhaps more primitive. The COSIMA mass spectrometer on board the ESA Rosetta spacecraft has detected more than 27,000 particles in the vicinity of comet...
