wants to find out how the building blocks of life are created. the vacuum chamber is designed to simulate phenomena like the clouds of. dust between the stars these clouds are huge and consist mostly of hydrogen plus tiny carbon and silicon dust particles. and. those dense molecular clouds contain hydrogen and dust the dust just surrounded by a sheet of ice the ice consists mostly of water but also of other molecules such as carbon monoxide carbon dioxide or ammonia. the accumulation of gas and dust prevents radiation from neighboring stars from penetrating the clowned but there is one thing in space that has no problem breaking through to the deepest and coldest regions. the energy of the cosmic rays is so high that it can penetrate the
