NASA’s Coral Reef Airborne Laboratory (CORAL) to begin detailed survey of Coral Reefs

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new three-year NASA field expedition gets underway this year that will use advanced instruments on airplanes and in the water to survey more of the world’s coral reefs, and in far greater detail, than ever before.

The COral Reef Airborne Laboratory (CORAL) will measure the condition of these threatened ecosystems and create a unique database of uniform scale and quality.

Coral reefs, sometimes called the rainforests of the sea, are home to a quarter of all ocean fish species. They protect shorelines from storms and provide food for millions of people, yet very little of the world’s reef area has been studied scientifically.

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:

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)

Interpreting Wall Street’s wild swings benefits from perspective

 

F&M Investment Services - Raymond James - Clarksville, TNClarksville, TN – The stock market sell-off continued Monday, as the Dow Jones Industrial Average and other major domestic indices saw a significant drop in early morning trading, regained some ground as the day progressed, but still closed down 3% to 4% for the day.

Global markets were also down, notably in China, Hong Kong, Germany and the United Kingdom. The pullback appears to be driven by concern over slowing global growth, particularly as China’s economy (one of the world’s largest) falters, as well as the drop in commodity prices, namely oil.

Colby Wilson’s Atlanta Braves Report: Moylo the Maverick

 

Atlanta BravesClarksville, TN – In an up-and-down (mostly down) Atlanta Braves season, you take solace in the little things. Jace Peterson looking like a potential cornerstone, for instance. The A.J. Pierzynski Revival. The on-going delight that is watching Andrelton Simmons range deep into the hole, make the impossible backhanded stab, stop on a dime, set, load his cannon of an arm and throw a hustling batter out by two steps.

But the most enjoyable phrase we’ve heard all season happened last week:

“The Braves have purchased the contract of Peter Moylan from Triple-A Gwinnett.”

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.

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)

NASA study reveals Oceans Temperature Rise Slowed

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new NASA study of ocean temperature measurements shows that in recent years, extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans. Researchers say this shifting pattern of ocean heat accounts for the slowdown in the global surface temperature trend observed during the past decade.

Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory, Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized.

NASA’s Chandra X-ray Observatory detects X-Ray Light Echoes of far away Neutron Star

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Astronomers using NASA’s Chandra X-ray Observatory have discovered the largest and brightest set of rings from X-ray light echoes ever observed.

These extraordinary rings, produced by an intense flare from a neutron star, provide astronomers a rare chance to determine how far across the Milky Way galaxy the star is from Earth.

The rings appear as circles around Circinus X-1, a double star system in the plane of our galaxy containing a neutron star, the dense remnant of a massive star pulverized in a supernova explosion.

A light echo in X-rays detected by NASA’s Chandra X-ray Observatory has provided a rare opportunity to precisely measure the distance to an object on the other side of the Milky Way galaxy. The rings exceed the field-of-view of Chandra’s detectors, resulting in a partial image of X-ray data. (NASA/CXC/U. Wisconsin/S. Heinz)

NASA and University of Texas researchers find two seafloor troughs that could threaten East Antarctica Glacier

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers at the University of Texas at Austin, NASA and other research organizations have discovered two seafloor troughs that could allow warm ocean water to reach the base of Totten Glacier, East Antarctica’s largest and most rapidly thinning glacier.

The discovery likely explains the glacier’s extreme thinning and raises concern about its impact on sea level rise.

This is the East Antarctic coastline. Icebergs are highlighted by the sunlight, and the open ocean appears black. (NASA)
