If you went through grade school, you've probably already learned about evaporation. It happens when a liquid can be sitting in one place and its molecules become a gas. That's the process called evaporation. It can happen when liquids are cold or when they are warm.
Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations. According to the study, this is designed to help scientists evaluate water resource management, assess recent trends of evaporation throughout the globe and validate surface hydrologic models in various conditions.
Generally, evaporation is tough to measure. With this new research, scientists plan to share data in hopes of learning more about the hydrologic cycle and to assess trends for acceleration, which could impact our climate locally, nationally and globally.
For the first time, scientists have discovered an Earth-size alien planet in the habitable zone of its host star, an "Earth cousin" that just might have liquid water and the right conditions for life.Read Story >
