🚨JWST HAS DETECTED "SEMI HEAVY WATER" ON AN ALIEN WORLD The James Webb Space Telescope has found evidence of HDO, sometimes called semi heavy water, in the atmosphere of WASP-39b, a scorching gas giant around 700 light years away. HDO is water in which one hydrogen atom has been replaced by the heavier isotope deuterium. By measuring its abundance, scientists can now begin reconstructing where a planet formed, what material it accumulated and how its atmosphere changed over time. The inferre...
