Helium Rains in SATURN and JUPITER!!!
Hydrogen and helium are the two lightest and most common elements in the universe. Because of their ubiquitous nature, they are critical in cosmological nucleosynthesis and are essential elements of stars and giant planets. Hydrogen by itself in the observable universe provides clues to the origin and large-scale structures of galaxies.
However, scientists have struggled to determine what conditions are needed for the two elements to mix.
The simulation results are consistent with the idea that a large portion of the interior of Saturn has conditions such that hydrogen and helium phase separate. “This can account for the apparent discrepancy between the current evolutionary models for Saturn and observational data.”
In addition to being made mostly of hydrogen and helium, a characteristic of Jovian planets is that they radiate more energy than they take in from the sun. Various models of their evolution and structure have been developed to describe a relation between the age, volume and mass of the planet and its luminosity.
While this model works for Jupiter by modeling the energy radiation left over from its formation 4.55 billion years ago, it doesn’t exactly work for Saturn. Instead, the model seriously underestimates the current luminosity of Saturn.
So the researchers decided to try something different. They determined where helium and hydrogen mix as well as at what temperature they don’t mix.
It turned out the temperature where the two elements don’t mix is high enough that helium is “partially mixable over a significant fraction of the interior of the Jovian planets with the corresponding region of Saturn being larger than in Jupiter. “This, in fact, could change the current interior models of Saturn and Jupiter.”
These are beautiful pictures — very inspiring. I write science and science fiction poetry, so I always enjoy seeing new imagery.
Hi, visiting you here with smile and peace…Cheers
Hey starbozz, r u much interested in space research and informational studies abt space. thats really cool. I l keep on visiting your page for more info on spatial sciences. U too visit my page for more info abt gadgets and many technological science, movies, nature, foto-sharing, file-sharing and much much more…. ok thank u

wow awesome 😮
that really awesomenn mamme………….
ehmmm… awesome… 😀
Im visit your blog and post my comments… OK!
good post..about solar system
Good picture and nice posting. Talking about science is always interesting. Hydrogen is also potential to be an Energy alternative for Car in the future. But the challange is we don’t know yet on the technology?
tank`s man your blog it`s good

wow…very amazing,picure and nice post.
Nice to know your blog 🙂
Wew, your post is fantastic! You can optimized the details of hidrogen and helium.
Good news, friend and keep comment to my blog
benar kata bu rita your postingan is nice and good banget. blue suka white planetnya. give me your picturenya dong,my friend.
by the way.met akhir pekan ya.
salam hangat selalu
Nice post. 🙂
very interesting … that really cool posting.
nice post and picture. maybe helium and hydrogen doesn’t have any chemical romance that makes them hard to mix 😀
thankyou for visiting ^^
maybe,.
i must learn more from you,
nice blog 🙂
masya Allah…its the beauty pict
Waow..gambarnya indah..
🙂
wah sungguh indah yah ciptaan tuhan………….
