Inside Science News Service  Forsetius / flickr Jupiter might be having a change of heart. Literally.
New simulations suggest that Jupiter's rocky core has been liquefying, melting, and mixing with the rest of the planet's innards. With this new data, astronomers hope to better explain a recent puzzling discovery of a strange planet outside of our solar system.
"It's a really important piece of the puzzle of trying to figure out what's going on inside giant planets," said Jonathan Fortney, a planetary scientist at the University of California Santa Cruz who was not affiliated with the research.
Conventional planetary formation theory has modeled Jupiter as a set of neat layers with a gassy outer envelope surrounding a rocky core consisting of heavier elements. But increasing evidence has indicated that the insides of gas giants like Jupiter are a messy mixture of elements without strictly defined borders.
This new research on a melting Jovian core bolsters a mixing model of gas giant planets and would provide another avenue for heavier elements to flow throughout the planet.
"People have been working on the assumption that these planets are layered because it's easier to work on this assumption," said Hugh Wilson, a planetary scientist at the University of California Berkeley and a coauthor of the new research appearing in Physical Review Letters.
Although scientists had previously toyed with the idea of melting cores in large planets, nobody sat down and did the necessary calculations, said Wilson.
Scientists have to rely on calculations of Jupiter's core environment because the conditions there are far too extreme to recreate on Earth. Wilson and his UC-Berkeley colleague Burkhard Militzer used a computer program to simulate temperatures exceeding 7,000 degrees Celsius and pressures reaching 40 million times the air pressure found on Earth at sea level.
Those conditions are thought to be underestimates of the actual conditions inside Jupiter’s core. Nonetheless, the authors found that magnesium oxide -- an important compound likely found in Jupiter's core -- would liquefy and begin drifting into Jupiter's fluid upper envelope under these relatively tame conditions.
Researchers believe that similarly-sized gas giant exoplanets -- planets found outside of our solar system -- probably have similar internal structures to Jupiter. Consequently, scientists were baffled earlier this year when they found a planet with approximately the same volume as Jupiter yet four to five times more mass.
Called CoRoT-20b, the new planet was announced in February, and its discoverers searched for a suitable explanation for its unusual density. Using conventional models, the astronomers calculated that the core would have to make up over half of the planet. For comparison, Jupiter's core only represents about between 3-15 percent of the planet’s total mass.
With a core that large, CoRoT-20b presented a huge problem for traditional assumptions surrounding planet formation.
"It's much easier to explain the composition of this planet under a model where you have a mixed interior," said Wilson.
Even the team that discovered the planet noted that a mixing model could allow for a more palatable planet density. Wilson's simulations not only add credence to the mixing model of giant planets but also suggest that this specific exoplanet's core is probably melting just like Jupiter's.
This melting may help explain why the exoplanet's heavy elements are likely stirred up and distributed throughout its volume, said Wilson.
Santa Cruz's Fortney agrees that most of the exoplanet's heavy elements likely reside in the outer envelope. Nonetheless, he expects other factors played a larger role in how the planet's interior became mixed: "It's more of a planet formation issue."
Several other events, such as two gas giants colliding together, might explain the ultra-high density of this new planet, Wilson admits. Certain processes may also limit the effectiveness of the melting and mixing process.
Liquefied parts of a gas giant's core may have trouble reaching the outer envelope due to double diffusive convection -- a process commonly found in Earth's oceans. When salty water accumulates at the bottom of the ocean, its density keeps it from mixing thoroughly with the upper layers. In a similar fashion, the heavy elements in Jupiter's core may have trouble gaining enough energy to move upward and outward.
Scientists don't know how much this hindrance will affect potential mixing inside Jupiter, and many other questions remain to be answered about the melting process.
"The next question is, 'How efficient is this process?'" said Fortney.
Researchers will have more tools to answer this question once NASA's Juno probe reaches Jupiter in 2016. With the spacecraft's instruments carefully analyzing Jupiter's composition, Wilson believes that there will be signatures of mixing and core erosion.

INCREDIBLE SUNSPOT AR1429: Big sunspot AR1429, the source of so many strong flares and geomagnetic storms earler this month, is still erupting. The active region produced a significant coronal mass ejection on March 24th at 00:39 UT. Because of the sunspot's location on the far side of the sun, this particular CME will not hit Earth. An animated forecast track prepared by analysts at the Goddard Space Weather Lab shows the trajectory of the expanding cloud:

The leading edge of the CME is espected to arrive at the STEREO-B spacecraft on March 25th at 13:08 UT (+/- 7 hours). None of the inner panets will be affected.

Since March began, sunspot AR1429 has propelled CMEs into every corner of the solar system, stirring up stormy space weather around every planet and spacecraft. If the sunspot remains active for another week or so, it will turn back toward Earth for a new round of geoeffective eruptions. Stay tuned.  ( my emphasis)

I don;t know about you, but right now the hairs are beginning to rise again, on the back of my arms.. no, not weer wolf time , not yet anyway...waiting for the moon......

still, looking at all the sudden swarms of earthquakes, and todays USGS map is particularly striking, one does get the feeling the Egyptian and Atlantean priests may have had, that , yes, we have seen this all before and it is its time for its return, it  has certainly made me think a bit harder about this whole thing.  I am in fact listening to Boris Artemenko for the umpteenth time, and maybe John Dinardp later. it has got me slightly rattled a little bit. and I mean it.  not just hyperbole .

so, listening to Bill Deagle on Fridays show, he made an interesting , almost tongue in cheek speculation that many of the nosies, the booms and such, may have been blasting out for the deep underground bases.

Now, imagine this little scenario. Something has been spotted, in fact this may be the secret mission of the space plane that is said to be in orbit still. . now this object has at last been seen, and maybe even  spotted on radar. its emissions have been detected by satellite and even earth bound telescopes, in the infra red.   so, a council of war was held, and the top brass at the Pentagon, FEMA, DHS, NSA and CIA plus the state department, and others, got together in secret, in fact may we speculate this was the main reason for David Cameron's recent visit? maybe also a few congressmen who could be trusted, with Q clearances no doubt. now imagine these men and women, and with  a group of tier one scientists advising and showing them the data. now imagine a decision was made, that even more urgency was needed to create or build afresh, more room  underground. so, in all haste they decided to expand and indeed  build afresh more storage and accommodation underground. so, ignoring the rumors and speculation by the alternative media and the public about the nosies they would make they got the blasting and tunneling machines down  to work, hence the noises we keep hearing, though many of these sounds may actually be the earth expanding and releasing gases and piezo electricity..

this is speculation, imagination, but it is worthy of consideration.

One last thing. every time I try to dismiss this planet x scenario as fantasy, the work of people with nothing else to do, -- like me maybe  LOL   then something else comes along, and the subject s thrown into the open once again. Jim maccaney made the observation yet again, that all these comets are coming from the south, think about it.

Did the Dimona Dozen murder the Fukushima 50? 3/11 was Japan’s 9/11.

This article needs greater exposure and distributed protection. It needs more than the few million reads it has had so far. Post it everywhere – even on your site, I don’t make money from this – the truth just NEEDS TO BE KNOWN. It really is US against the lie machine. Cache the pictures locally also, they MUST be available if I get taken down. If this truth does not get spread we WILL see more disasters just like Japan.

NHK released a bogus report – NHK PULLED IT, PROBABLY IN RESPONSE TO THIS SITE! – On Feb 26 2012, claiming they have the first aerial footage of Fukushima when far better aerial footage has been posted on this site since May of 2011! Furthermore, NHK modified their photos! What are they hiding? Well, what is reported here, of course!
