It is unbelievable that we were born on this planet and it is still a mysterious place. Scientists have been researching and learning more about things we did not know everything about Earth yet. We still need more advanced technologies to explore and find more discoveries in the oceans. In fact, oceans cover 2/3 part on Earth.
We did not know about the phenomenal geological features, the extreme conditions, and even all the living creatures deep under the sea. But, can you believe that there are some unfathomable oceans beyond our atmosphere? Hey, scientists also believe that there are some oceans on the solar system. We hope your brain will not explode reading these things!

10. The Oceans of Neptune and Uranus

Neptune and Uranus are two icy gas giants. These planets may host the incredible oceans in the shape of a diamond. In addition, these planets have similar mantles located beneath their atmosphere. The composition of the mantle is water, methane ices, and ammonia. Talking about the mantles, the temperature and the extreme conditions make the methane breaks up into the core components and produces pure carbon. For this reason, the mantles form into a diamond. The story is not over, here. The high pressure and intense heat make the diamonds melt. As a result, it forms diamond oceans at the base of the mantle.
Scientists then hypothesized through their experiments at the Livermore National Laboratory. What they did was recreating the extreme conditions of the giant mantles by using lasers to melt the diamonds into the liquid form.

9. Io’s Magma Ocean

In our solar system, Io is the most volcanic body that boasts over 400 volcanoes with explosions and lava flows on its surface. The thing that can explain the volcanic activity is the global magma ocean. The ocean is about 50 kilometers beneath the surface of the moon.
The Io’s peculiar orbit has an important role, here. It works to keep the ocean magma through two amazing heat generation methods. The orbit is between Jupiter and two of the Galilean moons known as Europea and Ganymede. The gravitational pull of the planet creates the tidal pumping and that is enough to create the amount of heat to keep the magma ocean in the form of liquid.

8. The Nuclear Ocean Of Pluto

Based on the low-resolution images along with the emission spectra, and inferred data from the orbits, scientists speculate the things on the surface of Pluto. They guess that it is possible if Pluto has an underwater ocean.
The surface temperature in Pluto is -230 degrees Celsius. Just like other planets in the solar system, there are many radioactive elements beneath the surface of this planet. Specifically, Pluto has potassium-40, uranium, and thorium.
It means once the elements undergo radioactive decay, they produce enough heat so that the water stays liquid. In other words, the surface of Pluto may be below freezing but this planet may have an underground nuclear ocean. The only way to disprove this scenario is when the New Horizons reaches Pluto.

7. Kepler-62 And The Ocean

Kepler 62e orbits the red dwarf star and there are five planets in its orbits, including Kepler-62e and 62f. About Kepler-62f, the position is a little bit far from its parent star. There is a big chance that the planet is completely frozen. On the other hands, Kepler-62e’s orbit is at a distance on par with the Mercury’s. In addition, the parent star is much cooler compared to the sun, so that Kepler-62e is still a habitable planet. But, there is a high possibility if the global ocean can exist. We cannot reveal many things whether the planet is a wet world in the solar system. The only way is to get closer to Kepler 62e.

6. Kepler-22b And The Ocean of Exoplanet

When it comes to an ocean planet that offers a habitable zone, we can include Kepler-22b on the list. In fact, some astronomers call it the Goldilocks region. The reason is that the surface temperature is not too hot and not too cold. For this reason, the surface has liquid water. We all know that water is essential to support life. It also means that the distance world can offer extraterrestrial life.
Unfortunately, just because the planet is categorized as the habitable zone, it does not mean that it is going to have water. Based on speculations, some astronomers said that Kepler-22b can be a smaller gas giant. It is hard to say that the planet is the Earth’s twin. Kepler Deputy Science Chief, Natalie Batalha said that there is still a possibility of life in such an ocean.

5. The Underground Ocean Of Enceladus

There are four “tiger stripes” across the southern polar region of Saturn’s sixth-largest moon with the cryovolcanic activity. The activity sprays 250 kilograms of water vapor per second. Most of the water vapor falls back to the moon’s surface. Others go into the Saturn’s outer E Ring.
Based on the analysis related to the E Ring, scientists discovered ice grains contained sodium salts. The salts are as similar as the salts from an ocean. Therefore, it sparked the idea that a salty underground ocean does exist in this place.
The flyby missions were done in 2012. Cassini then confirmed the existence of the ocean by detecting the gravitational signal of the water. They could determine the ocean of liquid water beneath the surface with the volume as equal as the Lake Superior.

 4. The Underwater Ocean of Ceres

In the asteroid belt, Ceres is the largest object. It is a tiny dwarf planet that is not bigger than the state of Texas. Ceres has a diameter of 950 kilometers. It is so tiny that scientists hardly believe that it has a muddy underwater ocean.
More about Ceres, the formation of this planet is no different from other planets in the solar system. The radioactive decay separated the planet into a rocky core and icy mantle. Since it has a small shape, Ceres could cool off quickly so that the surface was inactive and the ice was so solid. Until the Dawn Satellite performed a flyby, scientists discovered the bright object in a large crater. They speculate that it was “Feature 5” or it could be a cryovolcano. So, there is a possibility of an underground ocean located beneath the surface of Ceres.

3. The Biggest Ocean In The Solar System

Jupiter with its 50 kilometer thick destructive clouds has a mammoth ocean. The ocean is liquid hydrogen with a depth of 54, 531 kilometers.
Inside Jupiter, it has liquid hydrogen with the characteristic that scientists called it as the liquid metallic hydrogen. This pressure is high, that it is impossible to recreate the same thing on Earth. But, this is still a theory until now.

 2. Lobster Oceans

We are not talking about oceans that are full of lobsters. But, the oceans with the shape like a lobster. Theoretically, these oceans could exist on the exoplanets and they are locked so they could not rotate. It means that permanently they face toward their parent star. Various computer models explained that the oceans would be discovered on the side of the exoplanet. By using exoplanets from Gliese-581 system, there was a global ocean with the depth as similar to the Earth’s ocean. But, the atmosphere is full of carbon dioxide.
However, no one could discover the existence of lobster oceans up to now. But, it could be because until now, we have less powerful telescope technology to observe them.

1. The Lava Ocean Planet

Alpha Centauri, it is the start that is so close to our sun, located at 4.2 light-years away. The distant start has one planet orbiting it. Probably, there are several others. Scientists use various Doppler Effect techniques and they discovered that there was a planet, in a similar size as our earth, was orbiting Alpha Centauri B and they called it Centauri Bb.
But, it is wrong to say that Alpha Centauri Bb is the habitable zone. The condition in this place is like hell with three times hotter compared to the surface of Venus, the planet with the hottest surface temperature in the solar system.
With the very high temperatures, it can melt anything that exists on the planet’s surface. But, everything about Alpha Centauri Bb is still a theory. It is still under the debate of astronomers
