Although the chemistry on Earth and in interstellar clouds is much different, the results can be very similar. This and other recent studies show that prebiotic chemistry -- the formation of the molecular building blocks necessary for the creation of life -- occurs in interstellar clouds long before that cloud collapses to form a new solar system with planets. 'Many of the interstellar molecules discovered to date are the same kinds detected in laboratory experiments specifically designed to synthesize prebiotic molecules. This fact suggests a universal prebiotic chemistry,' said Jan M. Hollis of NASA's Goddard Space Flight Center in Greenbelt, MD. This suggests that the molecular building blocks for the creation of life on a new planet might get a head start in the dust of interstellar clouds.
The galaxy is a petri dish for life carrying planets. Very strange.
