Using Algorithms to Help Find Life on Icy Ocean Worlds

by Saima May Sidik 21 March 202521 March 2025

Scientists could use machine learning to analyze atmospheric samples in order to help identify microbes on frozen moons. They’re testing the concept using bottles of brine and smelly bacteria.

Looking for Life on Enceladus: What Questions Should We Ask?

Sarah Stanley, Science Writer by Sarah Stanley 8 May 202411 June 2024

On icy ocean worlds, a research framework built around the theory of organic chemical evolution could surface deeper insights than a hunt limited to direct evidence of life.

That’s No Moon; It’s an Ocean World

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 7 February 20248 January 2025

If Saturn’s cratered moon Mimas has liquid water beneath its surface, ocean worlds might be far more common in the solar system than we thought.

Uranus is a shiny blue-white orb, slightly off center in this image. Its rings are seen nearly face on, and six bright blue dots show the six brightest moons of the planet. There are several reddish galaxies in the background.
