Probe, Telescopes Tag Team to Spy Jupiter’s Great Red Spot

The spacecraft Juno prepares to fly over the great red spot of Jupiter, with a little help from his terrestrial probe friends.

On July 10, Juno only 5,600 miles (9,000 kilometers) above the century-old storm, about twice the diameter of Earth. The probe transform numerous instruments by determining what makes the storm and how it enters the gas giant.

But Juno scientists do not go blind: in the May telescopes, Subaru and Gemini North in Hawaii to measure coordinated Jupiter at different wavelengths, providing information on the atmosphere at different depths within the Great Red Act.

“Observations with Earth’s most powerful telescopes improve planned spacecraft observations by providing three additional types of context,” said Glenn Orton, a member of Juno’s science team at NASA’s Jet Propulsion Laboratory in California, at a statement.

“We have a spatial context to see the whole planet.” We extend and complement our temporal context by seeing functionality in time, and as a complement of different wavelengths of Juno. ”

This view of Jupiter in the observations in the middle infrared arrived on January 14 by the Subaru telescope in Hawaii, which enters the tropospheric warming. The camera and the infrared spectrometer through the cooled telescope (comics) captured images.

Researchers Gemini, Subaru, University of California, Berkeley and Tohoku University in Japan worked together to plan all observations completed on May 18, NASA officials said in the statement.

The Gemini North telescope examined Jupiter through near-infrared filters that absorb light from Jupiter’s high atmosphere and clouds, showing a long, well-structured wave of methane and hydrogen on the east side of a large red spot.

This false color image is from the Subaru telescope in Hawaii, taken using a medium infrared filter. May 18 is a longer wavelength than the one used for Gemini above the photograph, taken on the same night.) Large red spot appears as a cold region with a thick layer of clouds.
The same afternoon, researchers used the Subaru Telescope to investigate the mid-infrared, revealing different layers of the planet’s atmosphere.

Subaru’s view showed that within “cold and cloudy” the Great Red Spot increases toward its center, with a warmer and clearer periphery, Orton said. “A northwest of the region was exceptionally turbulent and chaotic, with cold and cloudy groups, alternating with bands that were warm and clear.”

Researchers can combine these new observations with other views on the gaseous ground-based telescope to determine what to expect for the dramatic flyby Juno. NASA’s Juno mission spent a year exploring the planet, starting July 4 and 32 exploring the planet orbiting the end of the mission in February 2018.
