Washington, July 23 (PTI) According to a study, large craters on Saturn's largest moon, Titan, are the best places to look for the building blocks of life.
With images and data from the spacecraft Cassini and Huygens Probe, scientists around Catherine Neish of the University of Western Ontario in Canada, on the best places in search of biological molecules on the surface of titanium.
The surface of titanium has abundant carbon-rich molecules (hydrocarbons) that have
However, titanium is far too cold to have liquid water on the surface.
Cassini radar measurements, orbiting Saturn for thirteen years, were able to peer through Titan's optically dense atmosphere, revealing the terrain of this enigmatic world.
Cassini's radar revealed lakes, dunes, mountains, river valley, and not many craters, suggesting that there are processes that re-emerge and fill or erode older craters.
The discovery of a similar world over nine times as far from the Sun was monumental, researchers said] Although methane lakes were perhaps the obvious choice to look for signs of life, researchers instead found craters and cryovolcanoes (regions where liquid water under Titan's icy surface breaks out) to the most enticing places.
Both features promise to melt the icy crust of titanium into liquid water, a necessary step to form complex biomolecules.
"When we mix Tholine (organic matter when simple gas mixtures are exposed to cosmic rays) with liquid water, we make amino acids very fast," said Morgan Cable of NASA's Jet Propulsion Laboratory in the US.
"So any place where liquid water is on the Titan surface or near its surface could produce the precursor ors to life ̵
