a Pole of Jupiter, as seen on Juno mission
Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought.
“We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. "It was a long trip to get to Jupiter, but these first results already demonstrate it was well worth the journey.”
Juno launched on Aug. 5, 2011, entering Jupiter’s orbit on July 4, 2016. The findings from the first data-collection pass, which flew within about 2,600 miles (4,200 kilometers) of Jupiter's swirling cloud tops on Aug. 27, are being published this week in two papers in the journal Science, as well as 44 papers in Geophysical Research Letters.
“We knew, going in, that Jupiter would throw us some curves,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “But now that we are here we are finding that Jupiter can throw the heat, as well as knuckleballs and sliders. There is so much going on here that we didn’t expect that we have had to take a step back and begin to rethink of this as a whole new Jupiter.”
Among the findings that challenge assumptions are those provided by Juno’s imager, JunoCam. The images show both of Jupiter's poles are covered in Earth-sized swirling storms that are densely clustered and rubbing together.
“We're puzzled as to how they could be formed, how stable the configuration is, and why Jupiter’s north pole doesn't look like the south pole,” said Bolton. “We're questioning whether this is a dynamic system, and are we seeing just one stage, and over the next year, we're going to watch it disappear, or is this a stable configuration and these storms are circulating around one another?”
Another surprise comes from Juno’s Microwave Radiometer (MWR), which samples the thermal microwave radiation from Jupiter’s atmosphere, from the top of the ammonia clouds to deep within its atmosphere. The MWR data indicates that Jupiter’s iconic belts and zones are mysterious, with the belt near the equator penetrating all the way down, while the belts and zones at other latitudes seem to evolve to other structures. The data suggest the ammonia is quite variable and continues to increase as far down as we can see with MWR, which is a few hundred miles or kilometers.
Prior to the Juno mission, it was known that Jupiter had the most intense magnetic field in the solar system. Measurements of the massive planet’s magnetosphere, from Juno’s magnetometer investigation (MAG), indicate that Jupiter’s magnetic field is even stronger than models expected, and more irregular in shape. MAG data indicates the magnetic field greatly exceeded expectations at 7.766 Gauss, about 10 times stronger than the strongest magnetic field found on Earth.
“Juno is giving us a view of the magnetic field close to Jupiter that we’ve never had before,” said Jack Connerney, Juno deputy principal investigator and the lead for the mission’s magnetic field investigation at NASA's Goddard Space Flight Center in Greenbelt, Maryland. “Already we see that the magnetic field looks lumpy: it is stronger in some places and weaker in others. This uneven distribution suggests that the field might be generated by dynamo action closer to the surface, above the layer of metallic hydrogen. Every flyby we execute gets us closer to determining where and how Jupiter’s dynamo works.”
Juno also is designed to study the polar magnetosphere and the origin of Jupiter's powerful auroras—its northern and southern lights. These auroral emissions are caused by particles that pick up energy, slamming into atmospheric molecules. Juno’s initial observations indicate that the process seems to work differently at Jupiter than at Earth.
Juno is in a polar orbit around Jupiter, and the majority of each orbit is spent well away from the gas giant. But, once every 53 days, its trajectory approaches Jupiter from above its north pole, where it begins a two-hour transit (from pole to pole) flying north to south with its eight science instruments collecting data and its JunoCam public outreach camera snapping pictures. The download of six megabytes of data collected during the transit can take 1.5 days.
“Every 53 days, we go screaming by Jupiter, get doused by a fire hose of Jovian science, and there is always something new,” said Bolton. “On our next flyby on July 11, we will fly directly over one of the most iconic features in the entire solar system -- one that every school kid knows -- Jupiter’s Great Red Spot. If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it’s Juno and her cloud-piercing science instruments.”
NASA's Jet Propulsion Laboratory in Pasadena, California, manages the Juno mission for NASA. The principal investigator is Scott Bolton of the Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers Program managed by NASA's Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate. Lockheed Martin Space Systems, in Denver, built the spacecraft.
Jingle bell, jingle bell, jingle bell rock
Jingle bells swing and jingle bells ring
Snowin' and blowin' up bushels of fun
Now the jingle hop has begun
Jingle bell, jingle bell, jingle bell rock
Jingle bells chime in jingle bell time
Dancin' and prancin' in Jingle Bell Square
In the frosty air
What a bright time, it's the right time
To rock the night away
Jingle bell time is a swell time
To go glidin' in a one-horse sleigh
Giddy-up jingle horse, pick up your feet
Jingle around the clock
Mix and a-mingle in the jinglin' feet
That's the jingle bell rock
Jingle bell, jingle bell, jingle bell rock
Jingle bell chime in jingle bell time
Dancin' and prancin' in Jingle Bell Square
In the frosty air
What a bright time, it's the right time
To rock the night away
Jingle bell time is a swell time
To go glidin' in a one-horse sleigh
Giddy-up jingle horse, pick up your feet
Jingle around the clock
Mix and a-mingle in the jinglin' feet
That's the jingle bell
That's the jingle bell
That's the jingle...

English Folk Song: The Wanderer and the Three Goannas
Lyrics (Based on the Warlpiri Story):
(Verse 1)
In the Tanami’s glow, where the spinifex sways,
Jupurrurla roamed through the desert’s warm days.
Her curious heart found a camp in the shade,
Where three goannas’ coolamons a feast had arrayed.
(Chorus)
Oh, the wanderer bold, ‘neath the starlit sky’s gleam,
Met the three goannas in the Desert’s dream.
With a heart full of truth, she learned to amend,
Wove the land and its kin in a song without end.
(Verse 2)
Father’s tomatoes sharp, Mother’s ants far too sweet,
But Little Goanna’s wattle warmed her heart’s beat.
On their mats she tried rest—too rough, then too slick—
Till the small one’s weave held her dreams soft and quick.
(Chorus)
Oh, the wanderer bold, ‘neath the starlit sky’s gleam,
Met the three goannas in the Desert’s dream.

I'm a little disappointed with my video. I couldn't put in the images I curated. But I stand by it. I am contributing to the debate over America Party. I'm a MAGA supporter always preferred GOP, despise RINO. I likely will never vote AP, but I welcome their existance in US Democracy, noting Dem's have utterly failed.
If the Democrat party is a corrupt, and ultimately spent force, what replaces it? Should we wait for a head to grow back? Or, should we look back to the vision of Jefferson and Adams? What is your preference for the future? I read all comments. Please like and subscribe.

Independence Day is a time for celebration. Here are some of the things this bill does. Doesnt it feel good to stop corruption and instead pay for what is needed? --- ### Ballad of the Big Beautiful Bill
Verse 1 Oh, gather 'round, ye hearts of cheer, this Independence Day, The Big Beautiful Bill has passed, and swept the rot away! No more the corrupt shall feast on bribes, their pockets lined with greed, The poor and lost now claim their due, their aid secured with speed.
Chorus Sing hallelujah, raise the flag, let freedom’s anthem soar, The truth has triumphed, justice reigns, from shore to shining shore! With open hearts and fearless dreams, we’ll build a world anew, The Bill has freed our spirits bold, and hope comes shining through!
Verse 2 The pharma lords, with wicked schemes, no longer spread their lies, Diseases sown for profit’s gain now wither 'neath our eyes. No more shall global bodies fake a warming doom’s decree, Fossil fuels, abundant, cheap, will power liberty!
