NASA Pinpoints Cause of Earth’s Recent Record Carbon Dioxide Spike

The last El Nino in 2015-16 impacted the amount of carbon dioxide that Earth’s tropical regions released into the atmosphere, leading to Earth’s recent record spike in atmospheric carbon dioxide. The effects of the El Nino were different in each region Credits: NASA/JPL-Caltech

NASA Pinpoints Cause of Earth’s Recent Record Carbon Dioxide Spike

NASA Pinpoints Cause of Earth’s Recent Record Carbon Dioxide Spike A new NASA study provides space-based evidence that Earth’s tropical regions were the cause of the largest annual increases in atmospheric carbon dioxide concentration seen in at least 2,000 years. Scientists suspected the 2015-16 El […]

This is a Test: Asteroid Tracking Network Observes Oct. 12 Close Approach

On Oct. 12, 2017, a small (15-30 meter) asteroid known as 2012 TC4 will safely fly past Earth. Based on continuing observations, scientists have determined that it will pass the Earth at a distance of about 26,000 miles (42,000 kilometers). Credits: NASA/JPL-Caltech

This is a Test: Asteroid Tracking Network Observes Oct. 12 Close Approach On Oct. 12, a small asteroid designated 2012 TC4 will safely pass by Earth at a distance of approximately 26,000 miles (42,000 kilometers). This is a little over one-tenth the distance to the […]

Mars Study Yields Clues to Possible Cradle of Life

This view of a portion of the Eridania region of Mars shows blocks of deep-basin deposits that have been surrounded and partially buried by younger volcanic deposits. The image was taken by the Context Camera on NASA's Mars Reconnaissance Orbiter and covers an area about 12 miles wide. Credits: NASA/JPL-Caltech/MSSS

Mars Study Yields Clues to Possible Cradle of Life

Mars Study Yields Clues to Possible Cradle of Life The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. A recent international report examines observations by NASA’s […]
