MANOA, Hawaii (University of Hawaii PR) — The first on-the-ground detection of water on the Moon’s surface was reported by an international team of researchers, including Shuai Li, a planetary geologist at the University of Hawaiʻi at Mānoa. Understanding the concentrations and distributions of water on the Moon is critical to understanding its formation and evolution, and to providing water resources for future human exploration.
Models and lab tests suggest the asteroid could be venting sodium vapor as it orbits close to the Sun, explaining its increase in brightness.
PASADENA, Calif. (NASA PR) — As a comet zooms through the inner solar system, the Sun heats it, causing ices below the surface to vaporize into space. The venting vapor dislodges dust and rock, and the gas creates a bright tail that can extend millions of miles from the nucleus like an ethereal veil.
