Scientists are currently searching for humanity’s genetic inheritance in frozen balls of ice orbiting our sun. Comets– once thought of as portents of disaster and destruction–may now be the answer to how complex life-forming molecules made their way to Earth.
ESA’s Rosetta Mission recently conducted an in-depth analysis of Comet 67P, gathering essential information on understanding how our Solar System was formed. During this mission, one of the instruments aboard Rosetta uncovered a mysterious ‘song’ the comet was emitting. Scientists believe the sound was produced by neutral particles being released from the comet’s interior core into space, where they become electrically charged due to a process called ionization.
