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…

Australian scientists sharpen James Webb telescope images with innovative software
Australian Researchers Sharpen James Webb Telescope Images When NASA launched the James Webb Space Telescope (JWST) in 2021, its mission hinged on keeping a razor-sharp view from a distance of about 1.5 million kilometers. A team of Australian scientists has now contributed a significant upgrade to that goal by refining Webb’s image quality through software…
