NASA’s Jason-2 satellite data points to possible El Niño in 2014

Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world’s oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate.

Lately, Jason-2 has seen something brewing in the Pacific—and it looks a lot like 1997.

NASA’s Curiosity Mars rover searches for next spot to drill

NASA - National Aeronautics and Space AdministrationPasadena, CA – The team operating NASA’s Curiosity Mars rover is telling the rover to use several tools this weekend to inspect a sandstone slab being evaluated as a possible drilling target.

If this target meets criteria set by engineers and scientists, it could become the mission’s third drilled rock, and the first that is not mudstone. The team calls it “Windjana,” after a gorge in Western Australia.

NASA's Curiosity Mars rover has driven within robotic-arm's reach of the sandstone slab at the center of this April 23 view from the rover's Mast Camera. The rover team plans to have Curiosity examine a target patch on the rock, called "Windjana," to aid a decision about whether to drill there. (NASA/JPL-Caltech/MSSS)

NASA’s Mars Curiosity rover stops to survey next Observations area

NASA - National Aeronautics and Space AdministrationPasadena, CA – On Wednesday, NASA’s Curiosity Mars rover drove the last 98 feet feet (30 meters) needed to arrive at a site planned since early 2013 as a destination for studying rock clues about ancient environments that may have been favorable for life.

The rover reached a vantage point for its cameras to survey four different types of rock intersecting in an area called “the Kimberley,” after a region of western Australia.

NASA's Curiosity Mars rover recorded this view of various rock types at waypoint called "the Kimberley" shortly after arriving at the location on April 2, 2014. (NASA/JPL-Caltech)

American Stroke Association reports awareness, response key for Stroke in Children

 

American Stroke Association - American Heart AssociationSan Diego, CA – Parents and healthcare professionals must be aware that children can have strokes and be prepared to respond to symptoms, according to research presented at the American Stroke Association’s International Stroke Conference 2014.

As in adults, warning signs of stroke in children are: sudden weakness or numbness of the face, arm or leg; sudden difficulty in speaking; sudden problems in seeing; sudden difficulty walking; dizziness; or sudden onset of headache.

NASA’s Deep Space Network celebrates 50 years of operation

 

Written by David Israel
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Deep Space Network, the world’s largest and most powerful communications system for “talking to” spacecraft, will reach a milestone on December 24th: the 50th anniversary of its official creation.

Over the past 50 years, antennas of the Deep Space Network (DSN) have communicated with just about every mission that has gone to the moon or beyond. The historic communiqués include “That’s one small step for man. One giant leap for mankind”; numerous encounters with the outer planets of our solar system; images taken by rovers exploring Mars; and the data confirming that NASA’s Voyager spacecraft had finally entered interstellar space.

Salon 615: It’s All About “The Voice”

 

Sandee Gertz - Author/Writer Nashville, TN – I’ve discovered another benefit of urban living in Downtown, Nashville: very cool neighbors.  Of course there are musicians and songwriters everywhere, and so when I passed my neighbor’s door and often heard him belting out classic rock tunes, I took him to be a touring musician who fronted a band.

I don’t know if what sealed that estimation was helped by the fact that he had long rocker-worthy hair, dressed in jeans and a T-shirt most days, and had this distinctively mellow yet baritone voice when he spoke going up and down on the elevator.

Austin Peay State University Tennis adds Three for Spring

 

APSU - Austin Peay State University SportsClarksville, TN – Head coach Ross Brown is pleased to announce a trio of mid-year additions to Austin Peay State University’s tennis teams. James Mitchell will join the Govs as they get set to defend their Ohio Valley Conference title, while Hannah Tatlock and Isabela Jovanovic join the women’s squad.

Mitchell hails from Australia, where he was a two-time All-Australia player for Lee Jarvinen at Applecross High School. He was a three-time Slazenger Cup captain and winner of the prestigious Australian cup in 2010, 2011 and 2012. He was also the National School’s captain in 2010 and 2011.

NASA Scientists work to detect Gravitational Waves created by merging Black Holes

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Throughout our universe, tucked inside galaxies far, far away, giant black holes are pairing up and merging. As the massive bodies dance around each other in close embraces, they send out gravitational waves that ripple space and time themselves, even as the waves pass right through our planet Earth.

Scientists know these waves, predicted by Albert Einstein’s theory of relativity, exist but have yet to directly detect one. In the race to catch the waves, one strategy — called pulsar-timing arrays — has reached a milestone not through detecting any gravitational waves, but in revealing new information about the frequency and strength of black hole mergers.

Merging black holes ripple space and time in this artist's concept. Pulsar-timing arrays -- networks of the pulsing cores of dead stars -- are one strategy for detecting these ripples, or gravitational waves, thought to be generated when two supermassive black holes merge into one.

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.
