All life on Earth depends on water, and the cycle of rain, rivers, oceans, and rain again is crucial to maintaining a stable and habitable climate. Planets with water are always at the top of the list when scientists discuss where to look for life throughout the galaxy. According to a recent study, there may be many more planets than previously believed that contain significant amounts of water, possibly even half of them being rock and half water. The problem? Instead of flowing as seas or rivers on the surface, all that water is likely entrenched in the rock. Rafael Luque, a postdoctoral researcher at the University of Chicago and the paper's first author, stated that it was unexpected to find evidence for so many water worlds orbiting the most prevalent form of star in the galaxy. It has significant ramifications for the search for terraforming planets. Scientists are discovering evidence of an increasing number of planets in distant solar systems as a result of improved telesco...

In Jiangxi Province, China, Poyang Lake regularly changes in size between the winter and summer seasons. Lake water levels are often low in the winter. The largest freshwater lake in the nation then fills up as a result of summer rains from the Yangtze River. However, in the summer of 2022, the lake has not risen. In fact, the lake dried up early and water levels dropped to levels not seen in decades as a result of a protracted heat wave and drought that affected much of the Yangtze River Basin.

For a larger, higher-resolution view, click the image. On June 23, Poyang Lake reached its highest water levels of the year (as measured at the Xingzi Station). According to the Jiangxi Hydrological Monitoring Center, following that, the lake's water levels dropped quickly due to the combination of high tempera...

The second-largest reservoir in the country, Lake Powell, is currently at its lowest elevation since it was filled in the middle of the 1960s. The aerial perspective is depressing. Lake Powell, a crucial part of the western U.S. water supply, is currently only 26 percent full. Since 1967, this is the lowest point. The lake's surface had a water elevation of 3,533.3 feet on August 22, 2022. More than 166 feet lower than "full pool" (elevation 3,700 feet). Parts of Lake Powell are visible in the natural-color satellite photos on this page, taken by the Landsat spacecraft in the summers of 2017 and 2022. The photos from 2017 were taken by the Operational Land Imager on Landsat 8, while those from 2022 were taken by the Operational Land Imager-2 on Landsat 9. Southeast Utah and northeastern Arizona share a boundary with Lake Powell; the majority of the area depicted is in Utah.
