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

NASA - National Aeronautics and Space AdministrationPasadena, 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)

AAA says Travel Concerns Push Vacation Prices Lower

 

AAA urges Americans to be informed when shaping 2016 travel plans

AAAKnoxville, TN – Media publicity regarding terrorism, the stock market, and now the Zika virus is weighing on the minds of travelers, many of whom are turning to AAA for advice on whether they should alter their vacation plans.

AAA always encourages Americans to be cautious when traveling the world, and to be aware of any health or security alerts before leaving. Although much has been made about the Zika virus, and travelers should stay informed, Federal health officials have not issued travel restrictions to those countries with active virus transmission.

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

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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)

Widow turns grief to gracious deed

2nd Brigade Combat Team - StrikeFort Campbell KY, 101st Airborne Division

Fort Campbell, KY – On the early, frosty morning of December 12th, 1985, Amy Gallo’s Tennessee home was filled with the aroma of freshly baked cinnamon rolls. They were her husband’s favorite, and he hadn’t had them in over six months.

Like many mothers, Gallo was juggling the sometimes overwhelming tasks of cooking, cleaning and tending to her two children. Her youngest, Sarita, had just began walking, and was exploring every square inch of their home with her newly-found ability.

Gallo’s then 3-year-old son Chip, was quietly sitting in the living room watching “He-Man,” a popular cartoon in the 1980s.

NASA begins Study into Rapid Climate Change in Alaska and Northwestern Canada

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As part of a broad effort to study the environmental and societal effects of climate change, NASA has begun a multi-year field campaign to investigate ecological impacts of the rapidly changing climate in Alaska and northwestern Canada, such as the thawing of permafrost, wildfires and changes to wildlife habitats.

The Arctic Boreal Vulnerability Experiment (ABoVE) will bring together on-the-ground research in Alaska and northwestern Canada with data collected by NASA airborne instruments, satellites and other agency programs, including the Soil Moisture Active Passive (SMAP), Orbiting Carbon Observatory-2 (OCO-2), and upcoming Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) and NASA-ISRO Synthetic Aperture Radar (NISAR) missions.

NASA's ABoVE campaign will combine field work, airborne surveys, satellite data and computer modeling to study the effects of climate change on Arctic and boreal ecosystems, such as this region at the base of the Alaska Range south of Fairbanks. (NASA/Ross Nelson)

NASA’s Gemini Planet Imager discovers young Jupiter like planet

 

NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – One of the best ways to learn how our solar system evolved is to look at younger star systems in the early stages of development. Recently, a team of astronomers including NASA scientists discovered a Jupiter-like planet within a young system that could serve as a decoder ring for understanding how planets formed around our sun.

The new planet, called 51 Eridani (Eri) b, is the first exoplanet discovered by the Gemini Planet Imager (GPI), a new instrument operated by an international collaboration, and installed on the 8-meter Gemini South Telescope in Chile.

Artistic conception of the Jupiter-like exoplanet 51 Eridani b, with the hot layers deep in its atmosphere glowing through the clouds. Because of its young age, this cousin of our own Jupiter is still hot and carries information on the way it was formed 20 million years ago. (Danielle Futselaar and Franck Marchis, SETI Institute)
