We present a testable hypothesis related to an origin of life on land in which fluctuating
volcanic hot spring pools play a central role. The hypothesis is based on experimental …

The origin of life is still one of humankind's great mysteries. At the transition between
nonliving and living matter, protocells, initially featureless aggregates of abiotic matter, gain …

Measurements of trace gases in planetary atmospheres help us explore chemical conditions
different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are …

Saturn's moon Enceladus has an ice-covered ocean; a plume of material erupts from cracks
in the ice. The plume contains chemical signatures of water-rock interaction between the …

Saturn's moon Enceladus emits plumes of water vapour and ice particles from fractures near
its south pole,,,,, suggesting the possibility of a subsurface ocean,,. These plume particles …

Saturn's moon, Enceladus, is a geologically active waterworld. The prevailing paradigm is
that there is a subsurface ocean that erupts to the surface, which leads to the formation of a …

While grounded in the hard sciences of physics, chemistry, geology, and astronomy, as well
as well-accepted principles in the life sciences, astrobiology remains the most speculative of …

The plume of Enceladus is unique in the solar system in providing direct access to fresh
material from an extraterrestrial subsurface ocean. The Cassini Mission, though not …

The detection of silica-rich dust particles, as an indication for ongoing hydrothermal activity,
and the presence of water and organic molecules in the plume of Enceladus, have made …

Astrobiology is the science that seeks to understand the story of life in our universe.
Astrobiology includes investigation of the conditions that are necessary for life to emerge …
