ESOcast 215 Light: Interstellar Thread of One of Life’s Building Blocks Revealed
Phosphorus, present in our DNA and cell membranes, is an essential element for life. But how it arrived on the early Earth is something of a mystery. Astronomers have now traced the journey of phosphorus from star-forming regions to comets using the combined powers of ALMA and the European Space Agency’s probe Rosetta.
