NASA’s Dawn Spacecraft observations of asteroid Vesta help scientists determine accuracy of Space and Ground based Telescopes

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Tantalized by images from NASA’s Hubble Space Telescope and ground-based data, scientists thought the giant asteroid Vesta deserved a closer look. They got a chance to do that in 2011 and 2012, when NASA’s Dawn spacecraft orbited the giant asteroid, and they were able to check earlier conclusions.

A new study involving Dawn’s observations during that time period demonstrates how this relationship works with Hubble and ground-based telescopes to clarify our understanding of a solar system object.

NASA’s Herschel Space Telescope links Comet Shoemaker-Levy 9’s Impact to water around Jupiter

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have finally found direct proof that almost all water present in Jupiter’s stratosphere, an intermediate atmospheric layer, was delivered by comet Shoemaker-Levy 9, which famously struck the planet in 1994.

The findings, based on new data from the Herschel space observatory, reveal more water in Jupiter’s southern hemisphere, where the impacts occurred, than in the north. Herschel is a European Space Agency mission with important NASA participation.

This map shows the distribution of water in the stratosphere of Jupiter as measured with the Herschel space observatory. White and cyan indicate highest concentration of water, and blue indicates lesser amounts. The map has been superimposed over an image of Jupiter taken at visible wavelengths with the NASA/ESA Hubble Space Telescope. (Image credit: Water map: ESA/Herschel/T.

NASA Scientist reports on Jupiter’s Global Climate Changes

 

Written by Jia-Rui Cook
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Jupiter, the mythical god of sky and thunder, would certainly be pleased at all the changes afoot at his namesake planet. As the planet gets peppered continually with small space rocks, wide belts of the atmosphere are changing color, hotspots are vanishing and reappearing, and clouds are gathering over one part of Jupiter, while dissipating over another.

The results were presented today by Glenn Orton, a senior research scientist at NASA’s Jet Propulsion Laboratory, Pasadena, CA, at the American Astronomical Society’s Division for Planetary Sciences Meeting in Reno, NV.

NASA’s Wide-field Infrared Survey Explorer (WISE) images shows Dust Disk orbiting Young Star has Mysteriously Disappeared

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Imagine if the rings of Saturn suddenly disappeared. Astronomers have witnessed the equivalent around a young sun-like star called TYC 8241 2652. Enormous amounts of dust known to circle the star are unexpectedly nowhere to be found.

“It’s like the classic magician’s trick: now you see it, now you don’t. Only in this case we’re talking about enough dust to fill an inner solar system and it really is gone!” said Carl Melis of the University of California, San Diego, who led the new study appearing in the July 5th issue of the journal Nature.
