NASA’s AIM spacecraft data shows Teleconnections in Earth’s Atmosphere linking Climate and Weather across the Globe

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Earth’s poles are separated by four oceans, six continents and more than 12,000 nautical miles.

Turns out, that’s not so far apart.

New data from NASA’s AIM spacecraft have revealed “teleconnections” in Earth’s atmosphere that stretch all the way from the North Pole to the South Pole and back again, linking weather and climate more closely than simple geography would suggest.

Over 700 new planets discovered by NASA’s Kepler Mission

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler mission announced Wednesday the discovery of 715 new planets. These newly verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system.

NASA researchers prepare to create Coldest Spot in the Universe inside International Space Station

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Everyone knows that space is cold. In the vast gulf between stars and galaxies, the temperature of gaseous matter routinely drops to 3 degrees K, or 454 degrees below zero Fahrenheit.

It’s about to get even colder.

NASA researchers are planning to create the coldest spot in the known universe inside the International Space Station.

NASA’s Kepler Space Telescope observations brings new Insight about Planets Kepler’s discovered

 

Written by Michele Johnson
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – More than three-quarters of the planet candidates discovered by NASA’s Kepler spacecraft have sizes ranging from that of Earth to that of Neptune, which is nearly four times as big as Earth. Such planets dominate the galactic census but are not represented in our own solar system. Astronomers don’t know how they form or if they are made of rock, water or gas.

The Kepler team issued a report on four years of ground-based follow-up observations targeting Kepler’s exoplanet systems at the American Astronomical Society meeting in Washington. These observations confirm the numerous Kepler discoveries are indeed planets and yield mass measurements of these enigmatic worlds that vary between Earth and Neptune in size.

NASA’s Opportunity Rover continues to explore Mars after a Decade

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Eighth graders didn’t have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning’s Channel One news in her Fredericksburg, Texas, classroom caught her eye.

“I wasn’t particularly interested in space at the time,” she recalled last week inside the spacecraft operations facility where she now works at NASA’s Jet Propulsion Laboratory in Pasadena, CA. “I remember I was talking with friends, and out of the corner of my eye I noticed this thing bouncing and rolling on a red surface. I watched as it stopped and opened up, and it had this rover inside.”

NASA's Mars Exploration Rover Opportunity observed this outcrop on the "Murray Ridge" portion of the rim of Endeavour Crater as the rover approached the 10th anniversary of its landing on Mars.

NASA’s Kepler Space Telescope data reveals First Earth-size Rocky Planet

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have discovered the first Earth-size planet outside the solar system that has a rocky composition like that of Earth. Kepler-78b whizzes around its host star every 8.5 hours, making it a blazing inferno and not suitable for life as we know it. The results are published in two papers in the journal Nature.

“The news arrived in grand style with the message: ‘Kepler-10b has a baby brother,’” said Natalie Batalha, Kepler mission scientist at NASA’s Ames Research Center in Moffett Field, CA. Batalha led the team that discovered Kepler-10b, a larger but also rocky planet identified by NASA’s Kepler spacecraft.

This illustration compares Earth with the newly confirmed scorched world of Kepler-78b. Kepler-78b is about 20 percent larger than Earth and is 70% more massive. Kepler-78b whizzes around its host star every 8.5 hours, making it a blazing inferno. (David A. Aguilar (CfA))

NASA Gravity Recovery and Climate Experiment spacecraft data reveals Australia had Biggest Role in Sea Level Drop

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise during that time, finds a new study co-authored and co-funded by NASA.

In 2011, scientists at NASA’s Jet Propulsion Laboratory in Pasadena, CA, and the University of Colorado at Boulder reported that between early 2010 and summer 2011, global sea level fell sharply, by about a quarter of an inch, or half a centimeter.

Areas in greens and blues depict the greatest increases in mass, caused by excessive precipitation. The contour lines represent various land surface elevations. (Credit: NCAR/NASA/JPL-Caltech)

NASA asks “Is a Sleeping Climate Giant Stirring in the Arctic?”

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Flying low and slow above the wild, pristine terrain of Alaska’s North Slope in a specially instrumented NASA plane, research scientist Charles Miller of NASA’s Jet Propulsion Laboratory, Pasadena, CA, surveys the endless whiteness of tundra and frozen permafrost below.

On the horizon, a long, dark line appears. The plane draws nearer, and the mysterious object reveals itself to be a massive herd of migrating caribou, stretching for miles. It’s a sight Miller won’t soon forget.

Permafrost zones occupy nearly a quarter of the exposed land area of the Northern Hemisphere. NASA's Carbon in Arctic Reservoirs Vulnerability Experiment is probing deep into the frozen lands above the Arctic Circle in Alaska to measure emissions of the greenhouse gases carbon dioxide and methane from thawing permafrost - signals that may hold a key to Earth's climate future.
