As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and young stellar objects as its immediate products.
Carbon capture and storage (CCS) (or carbon capture and sequestration) is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation.
Green plants use carbon dioxide during photosynthesis, in which carbon dioxide and water are used to produce glucose (which gives the plant energy) and oxygen. Plants are known as carbon sinks because they absorb carbon dioxide from the atmosphere and âfixâ or hold onto carbon in the form of glucose within their tissues.
