NASA scientists have
confirmed the presence of chemical vinyl cyanide through data collected
by the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.
Although this chemical is typically used on Earth to make acrylic
garments and tent fabrics, under the right conditions on Titan, they
could form flexible structures like cell membranes.
Produced
synthetically on Earth by converting hydrocarbon methyl ethylene, units
of hydrocarbons are strung together to form polymers or mixed with other
chemicals to create fibres. On Titan, the moon's rich abundance of
hydrocarbons in the atmosphere could theoretically do the same process.
"We
found convincing evidence that acrylonitrile is present in Titan's
atmosphere, and we think a significant supply of this raw material
reaches the surface," said lead researcher Maureen Palmer from NASA's
Goddard Space Flight Centre.
Previous studies had suggested the
possibility of vinyl cyanide existing on Titan, but until this
discovery, the chemical could not have been verified on the moon of
Saturn. This verification is another nudge towards the possibility of
life existing on other worlds - even in forms less conventional.
