A European space probe found complex and solid organic molecules, which are the building blocks of life, in dust particles surrounding a comet. The organic molecules were discovered by the European Space Agency's Rosetta probe and are the first clear evidence of solid organic matter around a comet. "Our analysis reveals carbon in a far more complex form than expected," Dr. Hervé Cottin, one the scientists who discovered the molecules, said in a statement. "It is so complex, we can't give it a proper formula or a name!" The discovery supports new scientific theories that the building blocks of life on the surface of space rocks. NASA is sending the OSIRIS-REx probe to the asteroid Bennu in 2018 where it will acquire samples of the asteroid using the Solo cup-inspired reverse vacuum device. The 4,650-pound, $800 million spacecraft will launch during a 34-day window this September and should reach Bennu sometime in 2018. The probe will collect up to four pounds of material from Bennu and
