“Methane Bubbles Frozen in Lake Baikal” is copyrighted by Kristina Makeeva. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteLake Baikal in Russia, the world's deepest and oldest freshwater lake, contains vast amounts of methane. These frozen bubbles in the lake's ice are pockets of methane gas. While most of the methane remains trapped, its potential release is a subject of scientific study due to its role as a greenhouse gas.
