A sacred Tibetan lake, a crack in the Antarctic ice shelf and deforestation in Cambodia are among images captured by Nasa and the ESA this month
Yamzho Yumco (Sacred Swan) Lake is one of the three largest sacred lakes in Tibet. It is surrounded by snow-capped mountains and is highly crenellated with many bays and inlets. The lake is home to the Samding monastery which is headed by a female reincarnation, Samding Dorje Phagmo. The image covers an area of 49.8km by 60km. Aster images map and monitor the changing surface of our planet, such as glacial advances and retreats; potentially active volcanoes; crop stress; cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.
