Problem: Does this sound correct? A Spectroscopy from spacecraft like Cassini helped with defining Enceladus' surface composition, by checking the spectroscopy of infrared and visible light which revealed to us the surface is mostly water ice. By examining its composition using a mass spectrometer, Cassini also flew over plumes erupting from Enceladus' south pole, and it confirmed the surface's chilly and chemically rich composition by finding water vapor, salts, ammonia, and organic molecules. B As we discovered evidence of an underground ocean below Enceladus's ice crust, scientists believe that life could exist under its surface. Liquid water, heat from tidal flexing, and organic chemicals found in the plumes point to conditions similar to what we found in the Earth's deep-sea hydrothermal vents where life develops without sunlight. These elements make Enceladus among the most likely sites for alien life searches. Need Assignment Help?
