Decoding Deuterium in Saturn’s Ice: JWST Reveals Uniform D/H in Moon Water
Overview: Probing the D/H Ratio in Saturn’s Moon Ice The deuterium-to-hydrogen (D/H) ratio in water ice is a key fingerprint of how water formed and evolved in the early solar system. In giant planet systems, the D/H value can preserve the history of solid materials—ices and pebbles—that coalesced into moons, and it can reflect the…

Deuterated Water Ice on Saturn’s Satellites: Unveiling D/H Ratios
New JWST Detections Reveal Deuterium-Enriched Ice on Saturnian Moons The deuterium-to-hydrogen (D/H) ratio in water ice is a key tracer of how and where planetary bodies acquired their water. A recent study using the James Webb Space Telescope (JWST) reports robust spectroscopic detections of the 4.14 μm O-D stretch absorption on mid-sized Saturnian satellites. This…

Water’s Surprising Dual Nature: A Solid and a Liquid in One Under Tight Confines
Water’s Counterintuitive State Under Confinement Water is usually seen as either a liquid or a solid—depending on whether you’re in the ocean or in a freezer. Yet a team of scientists in Japan has revealed a striking anomaly: when water is forced into extremely tight spaces, its molecules can behave as if they are both…
