NASA’s Landsat-5 satellite used to detect Underground Forest Fungi from Space

NASA - National Aeronautics and Space AdministrationPasadena, CA – A NASA-led team of scientists has developed the first-ever method for detecting the presence of different types of underground forest fungi from space, information that may help researchers predict how climate change will alter forest habitats.

Hidden beneath every forest is a network of fungi living in mutually beneficial relationships with the trees. Called mycorrhizal fungi, these organisms spread underground for miles, scavenging for nutrients that they trade with trees for sugars the trees make during photosynthesis. “Nearly all tree species associate with only one of two types of mycorrhizal fungi,” explained coauthor Richard Phillips of Indiana University, Bloomington.

NASA’s Dawn Spacecraft provides high resolution details of Bright Spots and complex features on Dwarf Planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists from NASA’s Dawn mission unveiled new images from the spacecraft’s lowest orbit at Ceres, including highly anticipated views of Occator Crater, at the 47th annual Lunar and Planetary Science Conference in The Woodlands, Texas, on Tuesday.

Occator Crater, measuring 57 miles (92 kilometers) across and 2.5 miles (4 kilometers) deep, contains the brightest area on Ceres, the dwarf planet that Dawn has explored since early 2015. The latest images, taken from 240 miles (385 kilometers) above the surface of Ceres, reveal a dome in a smooth-walled pit in the bright center of the crater.

A look at NASA’s Dawn spacecraft year of Orbiting dwarf planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One year ago, on March 6th, 2015, NASA’s Dawn spacecraft slid gently into orbit around Ceres, the largest body in the asteroid belt between Mars and Jupiter.  Since then, the spacecraft has delivered a wealth of images and other data that open an exciting new window to the previously unexplored dwarf planet.

“Ceres has defied our expectations and surprised us in many ways, thanks to a year’s worth of data from Dawn. We are hard at work on the mysteries the spacecraft has presented to us,” said Carol Raymond, deputy principal investigator for the mission, based at NASA’s Jet Propulsion Laboratory, Pasadena, California.

NASA Study reveals Sierra Snow can be reduced by Atmospheric River Storms

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new study by NASA and several partners has found that in California’s Sierra Nevada, atmospheric river storms are two-and-a-half times more likely than other types of winter storms to result in destructive “rain-on-snow” events, where rain falls on existing snowpack, causing it to melt. Those events increase flood risks in winter and reduce water availability the following summer.

The study, based on NASA satellite and ground-based data from 1998 through 2014, is the first to establish a climatological connection between atmospheric river storms and rain-on-snow events. Partnering with NASA on the study were UCLA; Scripps Institution of Oceanography, San Diego; and the Earth System Research Laboratory, Boulder, Colorado.

NASA creates animated view of Dwarf Planet Ceres using Dawn Spacecraft images

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A colorful new animation shows a simulated flight over the surface of dwarf planet Ceres, based on images from NASA’s Dawn spacecraft.

The movie shows Ceres in enhanced color, which helps to highlight subtle differences in the appearance of surface materials. Scientists believe areas with shades of blue contain younger, fresher material, including flows, pits and cracks.

NASA’s Dawn Spacecraft photos reveal details of Dwarf Planet Ceres over 200 years since it’s discovery

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New Year’s Day, 1801, the dawn of the 19th century, was a historic moment for astronomy, and for a space mission called Dawn more than 200 years later. That night, Giuseppe Piazzi pointed his telescope at the sky and observed a distant object that we now know as Ceres.

Today, NASA’s Dawn mission allows us to see Ceres in exquisite detail. From the images Dawn has taken over the past year, we know Ceres is a heavily cratered body with diverse features on its surface that include a tall, cone-shaped mountain and more than 130 reflective patches of material that is likely salt. But on that fateful evening in 1801, Piazzi wasn’t sure what he was seeing when he noticed a small, faint light through his telescope.

Giuseppe Piazzi used this instrument, called a Ramsden Circle, to discover Ceres on January 1, 1801. The telescope is on display at the Palermo Observatory in Sicily. (NASA/JPL-Caltech/Palermo Observatory)

NASA’s Dawn spacecraft delivers photos from it’s lowest orbit of dwarf planet Ceres

 

Written by Elizabeth Landau / Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Dawn spacecraft, cruising in its lowest and final orbit at dwarf planet Ceres, has delivered the first images from its best-ever viewpoint. The new images showcase details of the cratered and fractured surface. 3-D versions of two of these views are also available.

Dawn took these images of the southern hemisphere of Ceres on December 10th, at an approximate altitude of 240 miles (385 kilometers), which is its lowest-ever orbital altitude. Dawn will remain at this altitude for the rest of its mission, and indefinitely afterward. The resolution of the new images is about 120 feet (35 meters) per pixel.

This image of Ceres was taken in Dawn's low-altitude mapping orbit around a crater chain called Gerber Catena. A 3-D view is also available. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

Knoxville, TN | Thompson-Boling Arena

Tennessee Volunteers - UT VolsKnoxville, TN – Tennessee concludes its pre-Christmas schedule on Tuesday when welcomes in-state foe ETSU to Thompson-Boling Arena for a 7:00pm ET tipoff. A live streaming broadcast of the game will be available online only through SEC Network +.

The Vols (5-5) will be aiming to stay perfect at home this season as they are a perfect 5-0 at Thompson-Boling Arena in 2015-16. UT has showcased an uptempo and efficient offense in Knoxville, averaging 86.2 points per game in its five home wins. The senior duo of Kevin Punter Jr. and Armani Moore has been the catalyst behind those offensive figures as the tandem is putting up an average of 43.2 ppg at home.
