Salts and Organics Observed on Ganymede’s Surface by NASA’s Juno

NASA’s Juno mission has observed mineral salts and organic compounds on the surface of Jupiter’s moon Ganymede. Data for this discovery was collected by the Jovian InfraRed Auroral Mapper (JIRAM) spectrometer aboard the spacecraft during a close flyby of the icy moon. The findings, which could help scientists better understand the origin of Ganymede and […]

Water-Watching Satellite Monitors Warming Ocean off California Coast

The international Surface Water and Ocean Topography mission is able to measure ocean features, like El Niño, closer to a coastline than previous space-based missions. Warm ocean waters from the developing El Niño are shifting north along coastlines in the eastern Pacific Ocean. Along the coast of California, these warm waters are interacting with a […]

Cassini Data Reveals Building Block for Life in Enceladus’ Ocean

Phosphorus, a key chemical element for many biological processes, has been found in icy grains emitted by the small moon and is likely abundant in its subsurface ocean. Using data collected by NASA’s Cassini mission, an international team of scientists has discovered phosphorus – an essential chemical element for life – locked inside salt-rich ice grains […]

NASA Teams with Forest Service to Tally America’s Oldest Trees

Century-old sugar maples in Wisconsin. Five-hundred-year-old cedars in Oklahoma. Fifty-foot-wide oaks in Georgia. These trees grace our nation’s old-growth forests, and scientists say they hold unexplored mysteries from their roots to their rings. In an effort to steward these resources, on Earth Day 2022 the Biden Administration called upon the Department of Agriculture and the […]

NASA Space Mission Takes Stock of Carbon Dioxide Emissions by Countries

A NASA Earth-observing satellite has helped researchers track carbon dioxide emissions for more than 100 countries around the world. The pilot project offers a powerful new look at the carbon dioxide being emitted in these countries and how much of it is removed from the atmosphere by forests and other carbon-absorbing “sinks” within their borders. The […]
