Jupiter’s Storm Clouds

The more I look at this image the more I like it and it is little wonder this was NASA’s Image of the Day.

This was a submission on the JunoCam site. Be sure to check that site out too; maybe even download some images and see how you do.

This particular piece of work was done by citizen scientists Matt Brealey and Gustavo B C. Well done.

The original caption from NASA: This image captures a close-up view of a storm with bright cloud tops in the northern hemisphere of Jupiter.

NASA’s Juno spacecraft took this color-enhanced image on Feb. 7 at 5:38 a.m. PST (8:38 a.m. EST) during its 11th close flyby of the gas giant planet. At the time, the spacecraft was 7,578 miles (12,195 kilometers) from the tops of Jupiter’s clouds at 49.2 degrees north latitude.

Citizen scientist Matt Brealey processed the image using data from the JunoCam imager. Citizen scientist Gustavo B C then adjusted colors and embossed Matt Brealey’s processing of this storm.

Jupiter’s North Pole

NASA’s caption:  In this composite image, derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission to Jupiter, shows the central cyclone at the planet’s north pole and the eight cyclones that encircle it. JIRAM collects data in infrared, and the colors in this composite represent radiant heat: the yellow (thinner) clouds are about 9 degrees Fahrenheit (-13°Celsius) in brightness temperature and the dark red (thickest) are around -181 degrees Fahrenheit (83°Celsius).

Jupiter’s South Pole

I think this is my new favorite JunoCam image so far. The image above was from PeriJove 11 and the processing was masterfully done by Kevin M Gill and uploaded to the JunoCam site.

You can click the image above for a larger version although I recommend checking out this one at the JunoCam link to South Pole by Kevin Gill to see the wonderful detail in the full sized version.

I also realize I have a “new favorite” quite often, you might find another.  Here’s a link to this and other submissions on JunoCam

The Best So Far

Wow! What a great job by Kevin Gill the citizen scientist who produced this beautiful image of Jupiter using data from the JunoCam aboard the Juno spacecraft. I think this is the best JunoCam submission so far, really good. You can click the image above for a larger view and go to the JunoCam site to see the full sized version and it is worth it – seriously have a look.  Happily, you might disagree about this being the best so far; after all there ARE quite a few to choose from.

Don’t forget — YOU can also try your hand at working with the JunoCam data to create images like this.  In fact NASA has gone out of their way to make it easy,  When you have something you like you can even upload them to share on the NASA site.  How?  Easy, just go to the JunoCam Image Processing Gallery and click on the Submissions Guidelines link.

Here’s the original caption:

Colorful swirling cloud belts dominate Jupiter’s southern hemisphere in this image captured by NASA’s Juno spacecraft.

Jupiter appears in this color-enhanced image as a tapestry of vibrant cloud bands and storms. The dark region in the far left is called the South Temperate Belt. Intersecting the belt is a ghost-like feature of slithering white clouds. This is the largest feature in Jupiter’s low latitudes that’s a cyclone (rotating with clockwise motion).

This image was taken on Dec. 16, 2017 at 10:12 PST (1:12 p.m. EST), as Juno performed its tenth close flyby of Jupiter. At the time the image was taken, the spacecraft was about 8,453 miles (13,604 kilometers) from the tops of the clouds of the planet at a latitude of 27.9 degrees south.

The spatial scale in this image is 5.6 miles/pixel (9.1 kilometers/pixel).

Citizen scientist Kevin M. Gill processed this image using data from the JunoCam imager.

Near Jupiter’s Cloudtops

The Juno spacecraft was only 18,906 km / 11,747 miles above the cloud tops of Jupiter – pretty bold.

Here’s the original caption: See Jovian clouds in striking shades of blue in this new view taken by NASA’s Juno spacecraft.

The Juno spacecraft captured this image when the spacecraft was only 11,747 miles (18,906 kilometers) from the tops of Jupiter’s clouds — that’s roughly as far as the distance between New York City and Perth, Australia. The color-enhanced image, which captures a cloud system in Jupiter’s northern hemisphere, was taken on Oct. 24, 2017 at 10:24 a.m. PDT (1:24 p.m. EDT) when Juno was at a latitude of 57.57 degrees (nearly three-fifths of the way from Jupiter’s equator to its north pole) and performing its ninth close flyby of the gas giant planet.

The spatial scale in this image is 7.75 miles/pixel (12.5 kilometers/pixel).

Because of the Juno-Jupiter-Sun angle when the spacecraft captured this image, the higher-altitude clouds can be seen casting shadows on their surroundings. The behavior is most easily observable in the whitest regions in the image, but also in a few isolated spots in both the bottom and right areas of the image.

Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager.

JunoCam’s raw images are available at www.missionjuno.swri.edu/junocam for the public to peruse and process into image products.

Moon Shadow

What a nice image of a moon shadow on Jupiter.  Wanted to show this and hopefully I can in-between internet and power outages – it’s really windy and believe it or not most leaves are STILL on the trees.

Nice processing work on the Juno image from Gerald Eichstädt and Seán Doran (see below).  Image credit: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt and Seán Doran

More about Amalthea from NASA.  Click the image below for a larger version.

From NASA – Jupiter’s moon Amalthea casts a shadow on the gas giant planet in this image captured by NASA’s Juno spacecraft. The elongated shape of the shadow is a result of both the location of the moon with relation to Jupiter in this image as well as the irregular shape of the moon itself.

The image was taken on Sept. 1, 2017 at 2:46 p.m. PDT (5:46 p.m. EDT), as Juno performed its eighth close flyby of Jupiter. At the time the image was taken, the spacecraft was 2,397 miles (3,858 kilometers) from the tops of the clouds of the planet at a latitude of 17.6 degrees.

Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager. The image has been rotated so that the top of the image is actually the equatorial regions while the bottom of the image is of the northern polar regions of the planet.

Io and Europa

Another really great JunoCam image; this one processed by citizen scientist Roman Tkachenko.

NASA – This color-enhanced image of Jupiter and two of its largest moons — Io and Europa — was captured by NASA’s Juno spacecraft as it performed its eighth flyby of the gas giant planet.

The image was taken on Sept. 1, 2017 at 3:14 p.m. PDT (6:14 p.m. EDT). At the time the image was taken, the spacecraft was about 17,098 miles (27,516 kilometers) from the tops of the clouds of the planet at a latitude of minus 49.372 degrees.

Closer to the planet, the Galilean moon of Io can be seen at an altitude of 298,880 miles (481,000 kilometers) and at a spatial scale of 201 miles (324 kilometers) per pixel. In the distance (to the left), another one of Jupiter’s Galilean moons, Europa, is visible at an altitude of 453,601 miles (730,000 kilometers) and at a spatial scale of 305 miles (492 kilometers) per pixel.

Juno Looks at Jupiter’s Northern Lights

Jupiter has pretty impressive auroras as Juno can attest. This particular aurora in Jupiter’s north is not from the recent solar flare responsible for ours.  The CME associated with our current storm occurred on 04 September and arrived here late yesterday, so it has a ways to go before it gets to Jupiter – about 4 more AU.

This particular view is from Juno’s it was taken by Juno’s Ultraviolet Imaging Spectrometer (UVS) instrument on 11 December 2016 which also explains why Jupiter is not visible.

This could be just me, but the aurora looks sort of happy to be there.

SPECTACULAR!

A breath taking image and great work from citizen scientists Gerald Eichstädt and Seán Doran using data from  the Juno spacecraft and publicly available at JunoCam. Fantastic job!!!!  Be sure to click the image for  the larger version.

NASA’s caption: A dynamic storm at the southern edge of Jupiter’s northern polar region dominates this Jovian cloudscape, courtesy of NASA’s Juno spacecraft.

This storm is a long-lived anticyclonic oval named North North Temperate Little Red Spot 1 (NN-LRS-1); it has been tracked at least since 1993, and may be older still. An anticyclone is a weather phenomenon where winds around the storm flow in the direction opposite to that of the flow around a region of low pressure. It is the third largest anticyclonic oval on the planet, typically around 3,700 miles (6,000 kilometers) long. The color varies between red and off-white (as it is now), but this JunoCam image shows that it still has a pale reddish core within the radius of maximum wind speeds.

Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager. The image has been rotated so that the top of the image is actually the equatorial regions while the bottom of the image is of the northern polar regions of the planet.

The image was taken on July 10, 2017 at 6:42 p.m. PDT (9:42 p.m. EDT), as the Juno spacecraft performed its seventh close flyby of Jupiter. At the time the image was taken, the spacecraft was about 7,111 miles (11,444 kilometers) from the tops of the clouds of the planet at a latitude of 44.5 degrees.
