APSU professor Jack Deibert publishes book on historic 1868 survey of Wyoming

 

Austin Peay State University - APSUClarksville, TN – In 1871, geologist Ferdinand Hayden led the first federally funded geological survey into the Yellowstone region of northwestern Wyoming.

His findings, along with the work of his survey team, were instrumental in convincing Congress to establish Yellowstone as the first U.S. National Park, but a new book by Dr. Jack Deibert, Austin Peay State University professor of geology, sheds light on the historical significance of Hayden’s earlier journey into this region.

APSU’s Scott Raymond creates animated T-Rex Dinosaur for Nickelodeon’s Kids Choice Awards

 

APSU - Austin Peay State UniversityClarksville, TN – Despite how the old saying goes, at Austin Peay State University, those who can really do teach.

Assistant professor of animation Scott Raymond recently came to APSU following a successful career in computer animation, working for DreamWorks Animation on recent films, including “Kung Fu Panda 3,” “Home,” “Penguins of Madagascar” and “Mr. Peabody and Sherman.”

NASA’s Lunar Reconnaissance Orbiter discovers younger than expected Volcanic Activity on the Moon

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old.

This time period corresponds to Earth’s Cretaceous period, the heyday of dinosaurs. Some areas may be less than 50 million years old.

“This finding is the kind of science that is literally going to make geologists rewrite the textbooks about the moon,” said John Keller, LRO project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The feature called Maskelyne is one of many newly discovered young volcanic deposits on the Moon. Called irregular mare patches, these areas are thought to be remnants of small basaltic eruptions that occurred much later than the commonly accepted end of lunar volcanism, 1 to 1.5 billion years ago.

NASA reports Comet could possibly Collide with Mars in 2014

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Over the years, the spacefaring nations of Earth have sent dozens of probes and rovers to explore Mars.  Today there are three active satellites circling the red planet while two rovers, Opportunity and Curiosity, wheel across the red sands below. Mars is dry, barren, and apparently lifeless.

Soon, those assets could find themselves exploring a very different kind of world.

NASA reports Flyby of Earth could cause Seismic Activity on Asteroid 2012 DA14

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – For eons, Earth has felt the tremors of asteroids striking our planet. From the extinction of the dinosaurs 65 million years ago to the felled forests around Tunguska in 1908, the space rocks keep coming.

This week, Earth strikes back. When asteroid 2014 DA14 makes a record close approach to our planet on February 15th, the space rock could be the one feeling tremors.

Dinosaur Footprints found at NASA’s Goddard Space Flight Center Campus safely moved

 

Written by Karl B. Hille
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A grouping of 110 to 112 million-year-old dinosaur footprints pressed into mud from the Cretaceous Period have now been safely moved from their original setting on the grounds of NASA’s Goddard Space Flight Center in Greenbelt, MD.

Until further scientific study is possible, the footprints, now wrapped in protective material, will be stored on the Goddard campus.

This imprint shows the right rear foot of a nodosaur - a low-slung, spiny leaf-eater - apparently moving in haste as the heel did not fully settle in the cretaceous mud, according to dinosaur tracker Ray Stanford. It was found recently on NASA's Goddard Space Flight Center campus and is being preserved for study. (Credit: Ray Stanford)

Origin of Dinosaur-Killing Asteroid Remains a Mystery

 

Written by Whitney Clavin
Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Observations from NASA’s Wide-field Infrared Survey Explorer (WISE) mission indicate the family of asteroids some believed was responsible for the demise of the dinosaurs is not likely the culprit, keeping open the case on one of Earth’s greatest mysteries.

While scientists are confident a large asteroid crashed into Earth approximately 65 million years ago, leading to the extinction of dinosaurs and some other life forms on our planet, they do not know exactly where the asteroid came from or how it made its way to Earth. A 2007 study using visible-light data from ground-based telescopes first suggested the remnant of a huge asteroid, known as Baptistina, as a possible suspect.

Scientists think that a giant asteroid, which broke up long ago in the main asteroid belt between Mars and Jupiter, eventually made its way to Earth and led to the extinction of the dinosaurs. Data from NASA's WISE mission likely rules out the leading suspect, a member of a family of asteroids called Baptistina, so the search for the origins of the dinosaur-killing asteroid goes on. This artist's concept shows a broken-up asteroid. (Image credit: NASA/JPL-Caltech)
