Ocean Tides On Asynchronously Rotating Planets Orbiting Low-mass Stars
Planets in the liquid-water habitable zone of low-mass stars experience large tidal forces, 103 to 104 times those on Earth, due to the small distance between the habitable zone and […]

Water Planet Chemistry: Ocean Acidification Is More Pervasive Than Previously Thought
New research by an international team of oceanographers has found that ocean acidification has significantly compromised 40% of the global surface ocean, and 60% of the subsurface ocean to a […]

Noble Gas Depletion On Titan: Clathrate Sequestration During The Open Ocean Phase
A plausible explanation for the absence of primordial argon, krypton, and xenon in Titan’s current atmosphere is that these gases were sequestered in clathrate hydrates during Titan’s “open-ocean” phase.

JWST Reveals Spectral Tracers of Recent Surface Modification on Europa
Europa has been modified by a variety of geologic processes, exposing internally-derived materials that are heavily irradiated by charged particles trapped in Jupiter’s magnetosphere.

Were Earth’s Blue Oceans Once Green?
Scientists find evidence that our oceans used to be green, suggesting that this may be a sign of primitive life, including that on alien worlds.

When Did Earth’s Ocean Acidity Allow Life To Commence?
Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on […]
