Feb 6, 2015: Every 13 months, Earth and Jupiter have a close encounter. Astronomers call it an "opposition" because Jupiter is opposite the Sun in the sky. Our solar system’s largest gas planet rises in the east at sunset, and soars overhead at midnight, shining brighter than any star in the... Read More

Dec 31, 2014: It's active. It's passive. And it's got a big, spinning lasso. Scheduled for launch on Jan. 29, 2015, NASA's Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth's soils with an unprecedented accuracy and resolution. The instrument's three... Read More

Dec 31, 2014: A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study estimates that tropical forests absorb 1.4 billion metric tons of carbon dioxide out... Read More
