In a new study, self-sustaining chemical reactions were discovered which carry the potential to support alien life, which is very different from the elements present on Earth.
The biology of Earth hinges on organic compounds which comprise carbon along with elements like phosphorus, sulphur, nitrogen, oxygen and hydrogen. Scientists believe that alternative chemical frameworks can lead to the existence of alien life forms.
For long, scientists have wondered if alien life might evolve on the basis of significantly different chemistry. Researchers have speculated if silicon may work as a backbone for biology.
