These Squiggles May Be Some of the Oldest Fossil Life on Earth

Researchers say the fossils were left by 3.42-billion-year-old microbes. They could offer clues as to what sort of life may exist on other planets.

New clues to ancient life from billion-year-old lake fossils | Earth | EarthSky

We think of earthly life as evolving from the sea. But newly discovered microscopic "ball" fossils - found in ancient lake sediments in Scotland - suggest that evolution from single-celled to multi-cellular organisms might have occurred in lakes.

Below the verdant surface and organic rich soil, life extends kilometers into Earth's deep rocky crust. The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms — like a microbial coating of the rock surface.

EarthSky | Methane on Enceladus: A possible sign of life?

Something is producing a lot of methane on Enceladus, in its subsurface ocean. Could it be life? A new study seems to support that exciting possibility.

Buried beneath 20 kilometers of ice, the subsurface ocean of Enceladus—one of Saturn's moons—appears to be churning with currents akin to those on Earth. The theory, derived from the shape of Enceladus's ice shell, challenges the current thinking that the moon's global ocean is homogenous, apart
