Pasadena, CA – A series of atmospheric rivers that brought drought-relieving rains, heavy snowfall and flooding to California this week is highlighted in a new movie created with satellite data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite.

The images of atmospheric water vapor were collected by AIRS between January 7th and 11th. They show the amount of moisture present in the atmosphere and its movement across the Pacific Ocean to the United States, where much of it fell as rain or snow.

APSU College of Education prepares local teachers for 2017 Solar Eclipse

June 24, 2016 |

Clarksville, TN – On June 21st, Austin Peay State Univeristy (APSU) hosted an educational summit, “Preparing for the Big Event,” which provided elementary and middle school teachers from across Middle Tennessee with strategies on how to incorporate the eclipse into subjects such as science, mathematics, language arts, art and music.

More than 4,000 years ago, Chung K’ang, the fourth emperor of the Hea dynasty in China, reportedly executed two astronomers named Hi and Ho because they didn’t predict a solar eclipse.

NASA to use Spacecraft Orbiting Earth to track Air Pollution

April 26, 2016 |

Written by Steve Cole
NASA Headquarters

Washington, D.C. – For more than three decades NASA has focused its space-faring skills and science chops CSI-like on an elusive global killer. Later this month, that pursuit takes us to East Asia. In a few years, part way to the moon.

We are getting close.

Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available.

Satellites have documented that human-produced and natural air pollution can travel a long way. This 2014 NASA satellite image shows a long river of dust from western Africa (bottom of image) push across the Atlantic Ocean. (NASA)

NASA uses satellite data to solve questions about Earth’s rotational wobbles

April 9, 2016 |

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, CA – Using satellite data on how water moves around Earth, NASA scientists have solved two mysteries about wobbles in the planet’s rotation — one new and one more than a century old. The research may help improve our knowledge of past and future climate.

Although a desktop globe always spins smoothly around the axis running through its north and south poles, a real planet wobbles. Earth’s spin axis drifts slowly around the poles; the farthest away it has wobbled since observations began is 37 feet (12 meters).

Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth. (NASA/JPL-Caltech)

NASA researchers explore growing Food Crops during long Deep Space Missions

February 18, 2016 |

Written by Linda Herridge
NASA’s John F. Kennedy Space Center

Kennedy Space Center, FL – NASA plant physiologist Ray Wheeler, Ph.D., and fictional astronaut Mark Watney from the movie “The Martian” have something in common — they are both botanists. But that’s where the similarities end. While Watney is a movie character who gets stranded on Mars, Wheeler is the lead for Advanced Life Support Research activities in the Exploration Research and Technology Program at Kennedy Space Center, working on real plant research.

“The Martian movie and book conveyed a lot of issues regarding growing food and surviving on a planet far from the Earth,” Wheeler said. “It’s brought plants back into the equation.”

An artist concept depicts a greenhouse on the surface of Mars. Plants are growing with the help of red, blue and green LED light bars and a hydroponic cultivation approach. (SAIC)

NASA reports a strong, growing El Niño head to United States

December 31, 2015 |

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, CA – The current strong El Niño brewing in the Pacific Ocean shows no signs of waning, as seen in the latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission.

El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well.

The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño. The images can be viewed at:

The latest satellite image of Pacific sea surface heights from Jason-2 (left) differs slightly from one 18 years ago from Topex/Poseidon (right). In Dec. 1997, sea surface height was more intense and peaked in November. This year the area of high sea levels is less intense but considerably broader. (NASA/JPL-Caltech)

NASA examines Carbon emissions across the Earth to better understand our warming climate

November 15, 2015 |

Written by Kate Ramsayer, NASA Goddard Space Flight Center
and Carol Rasmussen, NASA’s Earth Science News Team

Washington, D.C. – Earth’s oceans and land cover are doing us a favor. As people burn fossil fuels and clear forests, only half of the carbon dioxide released stays in the atmosphere, warming and altering Earth’s climate. The other half is removed from the air by the planet’s vegetation ecosystems and oceans.

As carbon dioxide levels in the atmosphere continue their rapid, human-made rise past levels not seen for hundreds of thousands of years, NASA scientists and others are confronted with an important question for the future of our planet: How long can this balancing act continue? And if forests, other vegetation and the ocean cannot continue to absorb as much or more of our carbon emissions, what does that mean for the pace of climate change in the coming century?

NASA is advancing new tools like the supercomputer model that created this simulation of carbon dioxide in the atmosphere to better understand what will happen to Earth’s climate if the land and ocean can no longer absorb nearly half of all climate-warming CO2 emissions. (NASA/GSFC)

NASA sets the stage for upcoming Super Harvest Moon Eclipse

September 24, 2015 |

Science at NASA

Washington, D.C. – In the days before light bulbs, farmers relied on moonlight to help them harvest their crops. Many crops ripen all at once in late summer and early autumn so farmers found themselves extremely busy at this time of year. They had to work after sundown. Moonlight became an essential part of farming, and thus, the Harvest Moon was born.

According to folklore, the Harvest Moon is the full Moon that falls closest to the autumnal equinox, the hectic beginning of northern autumn. In 2015, the Moon is full on September 28th, less than a week after the equinox of September 23rd. The coincidence sets the stage for a nice display of harvest moonlight.
