Juno Spacecraft Reveals Spectacular Cyclones At Jupiter's Poles (arstechnica.com)

Joe Palca reports via NPR: NASA's Juno spacecraft has spotted giant cyclones swirling at Jupiter's north and south poles. That's just one of the unexpected and puzzling findings being reported by the Juno science team. Juno arrived at Jupiter last summer. It's the first spacecraft to get a close-up look at the planet's poles. It's in an orbit that takes it skimming close to the cloud tops of the gas giant once every 53 days. After each close pass, the spacecraft sends a trove of data back to Earth. Ultimately, scientists will want to understand how these cyclones change over time and whether they form differently in the north and south poles. Another puzzle that Juno is supposed to help solve is whether Jupiter, a gas giant, has a solid core. Another surprise from Juno is the concentration of ammonia in Jupiter's atmosphere. Scientists thought ammonia was most likely distributed evenly throughout the atmosphere. The data show there's more ammonia near the equator than there is at other latitudes.

    The MSM can claim it is a hoax all they want, and they will still lose. They can't win this, it is GAME OVER for them. With the internet getting censored, and the media full of lies, this is how we do it.

    Obviously Google is going to kick in the manipulation, to drive people to an approved answer to that question. So you can additionally kill this by writing "google sethrichdoc.jpg".

    They are not fooling ANYONE with ISIS anymore
    A couple days ago I reported about how ISIS (tm) had invaded the Philippines. Well, RT just covered the story. Here's some text, AND LOOK AT THE COMMENTS!

    Here is some article text:

    "The Maute group confronting the Philippine army in Marawi City is no longer considered a local terrorist organization as it has been reinforced by jihadists of Malaysian, Indonesian and "other nationalities, " the country's authorities have announced.

    "Before it was just a local terrorist group. But now they have subscribed to the ideology of ISIS. They want to make Mindanao as part of the caliphate, " Solicitor General Jose Calida told a news conference, according to Reuters.

    "What's happening in Mindanao is no longer a rebellion of Filipino citizens" but "has transmogrified into an invasion by foreign terrorists who heeded the clarion call of the ISIS to go to the Philippines if they find difficulty in going to Iraq or Syria, " Calida added, as cited by InterAksyon news.

    Now look at the comments!
    "As Philippines aligned towards China and Russia, US has activated its powerful operatives "ISIS", to create disturbance in Philippines."

    "He learned from his CIA class every terrorist need a adversary and every adversary needs a terrorist"

    "USA is a terrorist Country. NATO is a terrorist organization"

    " no comment you, re right mate absolutely 100%"

    "Duterte starts to have better relations with China and Russia - ISIS suddenly appears...."

    "Yeah. I'm surprised the regime change plan hasn't been enacted by now. It will start with protests in Manila followed by a violent, US-backed coup complete with US-paid mercenaries."

    "Trained in Syria by the CIA and MOSSAD"

    "Trained in Saudi Arabia and Jordan, not Syria."

    "Trained in Turkey as well"

    "Any of them wearing George Soros T-shirts?"

    "Oi Vey; I wonder who could possibly be behind this...."

    " The shekel masters?"

    "We Jews are the destroyers. We will always be the destroyers. Nothing you do will ever meet our needs and demands." - Maurice Samuel

    "and they question China building defenses right in the middle of the zone. China patrols the sea to try and prevent pirate terrorists doing business. The US patrols shouting its big mouth."

    " China should patrol the South China Sea , quietly escorting any American Navy vessels . China should also be very careful with Pakistan , its military officers are Wahhabi .

    "The early data are suggesting the presence of a core," Lunine says. "But not a discreet core. It seems that it's fuzzy." He says more data should help provide a more precise understanding than fuzzy.

    The core is being very discreet, hiding under all those clouds so we can't see it, and being very unobtrusive. It's not like it's out there waving itself around for everyone to see. I guess it leaves that to the flashy cloud layers and the Great Red Spot, which is a discrete formation that's been known for some time.

      Sure, some meteors will fall in. I'm not a physicist so I don't know the answer to this, but how does the mass density of hydrogen compare to other elements at the kind of pressures you get in the interior of a gas giant?

      They won't argue that the winds will destroy it, but that it will melt on the way down. Then you have a question of whether the materials chemically separate so that they can stratify or not (Earth's core is separate in part because some minerals and elements will mix with iron while others won't). Those processes depend a lot on temperature and pressure, and we might not be correctly extrapolating to those extremes. There are still questions about what the phase diagram of hydrogen looks like and how it behaves at those extremes.
