NASA Finds Material that Could Support Possible Life on Saturn’s Moon
Cassini also found evidence of several Earth-like qualities of Titan that could support life.

Another Cassini discovery involved the observation of hydrogen molecules in ice particles and vapor shooting upward from the moon’s surface.

microbial life. Now, the space agency is sharing a new finding that supports the earlier discoveries.

Scientists examining Cassini data said they identified “strong confirmation” of the presence of another molecule seen as important for enabling life.

Evidence of the molecule hydrogen cyanide was found in data relating to the same shooting flows of ice and water vapor observed by Cassini on Enceladus.

The team used data collected by an instrument aboard Cassini designed to measure the activity of gas, ions and ice particles around Saturn.

The new evidence is described in a study in Nature Astronomy by scientists from NASA’s Jet Propulsion Laboratory (JPL) in California.

The lead writer of the study, Jonah Peter, is currently a doctoral student at Harvard University.

He called the discovery of hydrogen cyanide “particularly exciting,” saying the molecule is “the starting point for most theories on the origin of life.”

NASA said in a statement that for life to exist in space, there must be collections of the right building blocks. One of the most important of these is amino acids.

“Hydrogen cyanide is one of the most important and versatile molecules needed to form amino acids,” NASA noted.

The researchers said hydrogen cyanide molecules can join together in many different combinations.

They can also serve as a precursor for different kinds of amino acids.

In addition, the latest examination of Cassini data suggested the underground ocean on Enceladus “holds a powerful source of chemical energy.”

“Unidentified until now, the energy source is in the form of several organic compounds, some of which, on Earth, serve as fuel for organisms,” NASA

said. Astronomers involved in the research said that the discovery provides fresh evidence that there may be more chemical energy inside Enceladus than previously thought.

The more energy that is available, the team said, the more likely it is that life can form and survive.

“Not only does Enceladus seem to meet the basic requirements for habitability said JPL’s Jonah Peter, “we now have an idea about how complex biomolecules could

form there, and what sort of chemical pathways might be involved.”

The search for possible life on Titan will continue when NASA launches its Dragonfly exploratory mission in 2026.

Dragonfly is a drone, or pilotless aircraft. The vehicle is designed to capture images and also land on Titan to collect data.
