Glaciers are a key indicator of climate change, the proverbial canaries in the coal mine. Studying past and present behavior of glaciers and analyzing possible long-term changes help governments to better understand the impacts of climate change on water resources.
The TSIS instrument on the International Space Station is continuing NASA's 40-year record of tracking the Sun's radiant energy.
Precise polarization measurements of the Cosmic Microwave Background (CMB) radiation, an ancient glow from the early universe, may help scientists better understand how the universe rapidly expanded in a burst called “inflation” moments after the Big Bang.
Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible.
The Perseid Meteor Shower peaks on the night of August 12 into the morning of August 13. With a clear sky, observers will be able to see up to 60 meteors per hour at its peak.
The Parker Solar Probe will help scientists learn more about the solar wind, an exotic stew of magnetic forces, plasma and particles.
