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

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)

UT Vols Basketball take on East Tennessee Buccaneers at Thompson-Boling Arena, Tuesday

 

Tennessee (5-5) vs. East Tennessee (5-5)

Tuesday, December 22nd, 2015 | 7:01pm ET (6:01pm CT)
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.

Tennessee Vols Basketball faces Gonzaga Bulldogs, Saturday

 

Tennessee (5-4) vs. Gonzaga (7-3)

Saturday, December 19th, 2015 | 11:00pm ET (10:00pm CT)
Seattle, WA | Keyarena

Tennessee Volunteers - UT VolsKnoxville, TN – Tennessee heads to the West Coast for the first time in six years when it takes on Gonzaga in the annual Battle in Seattle on Saturday night. The Vols and Bulldogs tip off at 11:00pm ET (10:00pm CT) on ESPNU.

The cross-country trip comes on the heels of an 81-62 win for Tennessee (5-4) over Florida Atlantic on Wednesday night. The victory snapped a three-game skid for the Volunteers and improved their home record to a perfect 5-0. UT is still seeking its first win away from Knoxville under head coach Rick Barnes — an ailment it will seek to remedy as it makes only its second-ever appearance in the Emerald City.

NASA’s Dawn spacecraft data reveals new insights into Dwarf Planet Ceres’ Bright Spots

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Ceres reveals some of its well-kept secrets in two new studies in the journal Nature, thanks to data from NASA’s Dawn spacecraft. They include highly anticipated insights about mysterious bright features found all over the dwarf planet’s surface.

In one study, scientists identify this bright material as a kind of salt. The second study suggests the detection of ammonia-rich clays, raising questions about how Ceres formed.

NASA’s Dawn spacecraft continues to provide insightful information about Dwarf Planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Mysteries and insights about Ceres are being discussed this week at the European Planetary Science Conference in Nantes, France. NASA’s Dawn spacecraft is providing scientists with tantalizing views and other data about the intriguing dwarf planet that they continue to analyze.

“Ceres continues to amaze, yet puzzle us, as we examine our multitude of images, spectra and now energetic particle bursts,” said Chris Russell, Dawn principal investigator at the University of California, Los Angeles.

NASA’s Dawn spacecraft captures high detail photos of Bright Spots on Dwarf Planet Ceres

 

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

NASA - National Aeronautics and Space AdministrationPasadena, CA – The brightest spots on the dwarf planet Ceres gleam with mystery in new views delivered by NASA’s Dawn spacecraft. These closest-yet views of Occator crater, with a resolution of 450 feet (140 meters) per pixel, give scientists a deeper perspective on these very unusual features.

The new up-close view of Occator crater from Dawn’s current vantage point reveals better-defined shapes of the brightest, central spot and features on the crater floor. Because these spots are so much brighter than the rest of Ceres’ surface, the Dawn team combined two different images into a single composite view — one properly exposed for the bright spots, and one for the surrounding surface.

This image, made using images taken by NASA's Dawn spacecraft, shows Occator crater on Ceres, home to a collection of intriguing bright spots. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA’s Dawn mission releases video that gives flyover perspective of dwarf Planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Striking 3-D detail highlights a towering mountain, the brightest spots and other features on dwarf planet Ceres in a new video from NASA’s Dawn mission.

A prominent mountain with bright streaks on its steep slopes is especially fascinating to scientists. The peak’s shape has been likened to a cone or a pyramid. It appears to be about 4 miles (6 kilometers) high, with respect to the surface around it, according to the latest estimates. This means the mountain has about the same elevation as Mount McKinley in Denali National Park, Alaska, the highest point in North America.
