Uranus and Neptune are also described as ice giants, and the idea that there is water there in some form is not new.
American planetary scientist Burkhard Militzer is now in the journal Proceedings of the National Academy of Sciences the theory suggested that beneath the hydrogen and helium-rich atmospheres of the planets is a layer of water and hydrogen, which in the case of Uranus is more than 8,000 kilometers deep.
Meanwhile, Uranus’ atmosphere is supposed to be about 4800 km thick. Although Neptune is larger than Uranus, it has a smaller overall diameter and a thinner atmosphere in comparison. However, according to Militzer’s paper published on Monday, they appear to share similar water-filled layers.

“We think it’s the ocean,” Militzer said. blade NOW note that this ocean would be under a pressure 60,000 times higher than the Earth’s surface, so it would be more like a mixture of gas and liquid than liquid water on Earth.

At the same time, Militzer believes that the same thick layer of highly condensed liquid consisting of carbon, nitrogen and hydrogen is underwater on Uranus and Neptune.
He reached a conclusion based on a computer model that simulated the conditions on these planets. The result of the simulation of individual pressure and temperature was the natural formation of individual layers.

“One day I looked at the model and the water was separated from the carbon and nitrogen,” Militzer said on the university’s website. Berkeley News. “I would say we now have a good theory as to why Uranus and Neptune have very different fields from the other planets,” he said.
He was referring to the magnetic fields of the planets, which are different from other planets in the solar system. The difference was already revealed by the Voyager 2 probe, which saw Uranus and Neptune more than 30 years ago. It turned out that the ice giants do not have a magnetic dipole field coming from the center of the planet like eg. The Earth, Jupiter or Saturn, however, has moved a magnetic field significantly away from the center of the planet and significantly away from the axis of rotation.

The discovery showed that deep inside the two planets there is a convective flow of conductive liquid that creates a dipole magnetic field.
- Convection sufficient conductive masses (liquid) are needed to move in and create a stable and strong planetary magnetic field through magnetic induction. Usually this happens within the centers of planets, but in the case of ice planets it seems to be different.
More than 20 years ago, two scientific teams offered the answer that Uranus and Neptune create layers that do not mix, preventing convection in their interior. Other experts believed that the inner layers of the planet were more mixed.
Militzer’s explanation now indicates that the chaotic appearance of the magnetic fields is caused by the upper layer full of water, which generates the magnetic field with its current.
“Until now, we basically knew nothing about the interior of the two planets,” said planetary scientist Adam Masters, working at Imperial College London, on the new theory.
“So this new hypothesis is very impressive,” he said.

How might the discovery of layered interiors in Uranus and Neptune influence our understanding of planet formation, and do you think this model could apply to other types of planets?
This article explores the recent theory about the unusual magnetic fields of Uranus and Neptune. Here are some open-ended questions to spark discussion and explore different viewpoints:
**About the Magnetic Fields and Planet Interiors:**
* How does the idea of separate layers within Uranus and Neptune, that don’t mix, challenge our understanding of how planetary interiors typically form and evolve?
* The article mentions convection as essential for creating a strong magnetic field. Can you think of other celestial bodies with unconventional magnetic fields, and what might explain their unique properties?
* What are the potential implications of Militzer’s theory for our understanding of other ice giant planets beyond our solar system?
* How might this discovery influence future space explorations and missions targeted at Uranus and Neptune?
**Relating to Scientific Discovery and Knowledge:**
* What role does computer modeling play in advancing our understanding of distant planets like Uranus and Neptune? What are the strengths and limitations of using models in this context?
* The article mentions previous theories about Uranus and Neptune’s magnetic fields. How does science progress when new evidence challenges existing understanding? Is it ever possible to be absolutely certain about scientific theories?
* What unanswered questions remain about Uranus and Neptune’s interiors? What future research could help us gain a more complete picture?
**Engaging with Broader Implications:**
* Why is it important to understand the internal structure and magnetic fields of planets like Uranus and Neptune? What insights can these studies provide about the formation and evolution of our solar system and others?
* How can understanding the conditions on other planets inform our own understanding of Earth and its environment?
**Ethical and Philosophical Considerations:**
* Does the exploration of distant planets raise any ethical considerations? For example, should we prioritize exploring planets with potentially habitable environments over those like Uranus and Neptune?
* How does our understanding of the vastness and diversity of the universe affect our perspective on our own place in the cosmos?
Remember to encourage participants to consider multiple perspectives, support their opinions with evidence from the article, and engage respectfully with differing viewpoints.
