Making a splash in search for interstellar water

more »
Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the special conditions found deep within frigid molecular clouds, where dust shields against destructive ultraviolet light and aids chemical reactions. NASA's James Webb Space Telescope will peer into these cosmic reservoirs to gain new insights into the origin and evolution of water and other key building blocks for habitable planets.

NASA's Webb Telescope to Make a Splash in the Search for Interstellar Water


NASA's Webb Telescope Will Map Cosmic Ices

Most of the water in the universe floats in vast reservoirs called molecular clouds. It coats the surface of dust grains, turning them into cosmic snowflakes. When stars and planets form, those snowflakes get swept up, delivering key ingredients for life. NASA’s James Webb Space Telescope will map water and other cosmic ices to gain new insights into these building blocks for habitable planets.

New 3-D measurements improve understanding of geomagnetic storm hazards

Measurements of the three-dimensional structure of Earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms.
