How Many Oceans are In the Solar System?
As the time passed we discovered that there is actually quite a lot of water in the solar system, and a chunk of it is in liquid form. So where are those oceans and how many of them are there?

Sounds of Saturn: Hear Radio Emissions of the Planet and Its Moon Enceladus
New research from the up-close Grand Finale orbits of NASA’s Cassini mission shows a surprisingly powerful interaction of plasma waves moving from Saturn to its moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear -- in the same way a radio translates electromagnetic waves into music. Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument Sept. 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.

Astronomy Cast Ep. 494: Icy Moons Update 2018
Join +Fraser Cain and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions! Thanks to Cassini and other spacecraft, we've learned a tremendous amount about the icy worlds in the Solar System, from Jupiter's Europa to Saturn's Enceladus, to Pluto's Charon. Geysers, food for bacteria, potential oceans under the ice and more. What new things have we learned about these places?
Life on Enceladus - Moon of Saturn
Enceladus is a moon of Saturn, and is one of the most promising places for alien life, in this video i take a look at how life could even exist here and i also take a look at another promising world for life Europa.

To be honest I can't remember where I came up with that one.

What Would Standing on Oceanic Moon Enceladus Feel Like?

Enceladus is a tiny oceanic moon orbiting a gas giant Saturn. So what would standing on this icy moon be like? In this video i discuss that. Intro, outro and other clips in the video made with Space Engine. Music: Kevin MacLeod - Crypto
The potential for life within Enceladus after Cassini
Planetary scientist Dr. Jonathan Lunine of Cornell University discusses the Cassini mission’s exploration of Enceladus and what that moon has taught us about ocean worlds in the outer solar system. Dr. Lunine stresses that Enceladus is the best candidate world at which life may exist beyond Earth in our solar system. This was the third presentation in the Lunar and Planetary Institute’s 2017–2018 Cosmic Exploration Speaker Series, “Diving into Ocean Worlds.”
Life Beneath the Ice. Why We Should Focus on Ocean Worlds to Find Life in the Universe
Forget rocky worlds like Earth and Mars. New discoveries about icy worlds like Europa and Enceladus make them the ideal candidates for the search for life in the Universe. In fact there could be hundreds, or even thousands of times more worlds out there with ability to support life. Of course, there’s a problem, how do we search for life when it’s hidden beneath kilometers of ice? Get an email announcement whenever we release a new video:

Chloe Cain - Instagram: @chloegwen2001 Decades ago, Mars seemed like the most viable place to search for life in the Solar System. The Red Planet is cold, dry and airless today, but it certainly seemed to have liquid water there in the ancient past. Of course, wherever we find liquid water here on Earth, we find life. At the bottom of the ocean, where the crushing pressures would kill us in a moment. In steaming volcanic vents. Beneath glaciers, deep underground, even huddled in nuclear reactor cooling tanks. NASA’s Mars exploration program has been following the story of water. Opportunity and Spirit discovered evidence that Mars had liquid water in the ancient past. And the Curiosity Rover doubled down on that, finding minerals that indicate there was water on the surface of Mars for a long time. But then, long ago, the conditions changed, Mars lost its atmosphere, became cold, dry and inhospitable to life. It’s possible that life could still be there on Mars, huddled underground in salty reserves that prevent the water from freezing or evaporating. But so far, scientists haven’t found it yet. This shows that life on rocky worlds is tenuous at best. Too close to the star, or too far. Not a thick enough atmosphere, or too thick, creates a world that’s inhospitable to life. And even if a world was, briefly a place worth calling home, main sequence stars are constantly putting out more radiation, shifting the habitable zone farther out. Think about how long Earth will be habitable. Life crawled out from the oceans 430 million years ago, and planetary scientists estimate we’ve only got another 500 million to a billion years before the Sun gets too hot and boils the oceans dry. But now we’re discovering there are other places in the Solar System to look for life - water worlds. In fact, the number of these places, and the amount of liquid water on them is difficult to wrap your brain around. The Earth is a desert compared to the amount of liquid water that’s out there in the Solar System. Europa alone has 2-3 times as much water on Earth. And this life could be safe and sound, protected from radiation, meteor impacts and nearby supernovae for billions of years. Long after the Sun has burned out and faded away.
Life on Enceladus? Saturn's ocean moon maybe to more than just water - TomoNews
ENCELADUS, SATURN — Scientists looking at data pulled from NASA's Cassini spacecraft may have found out how Saturn's ocean moon Enceladus remains geologically active. The research, published in Nature Astronomy, suggests that tidal currents flow through the moon's porous core, where the friction between rocks generate heat that warms the ocean. According to the European Space Agency, this tidal heating is primarily caused by the gravitational pull of Saturn. Writing in 2008, the space agency speculated that the deep sea vent theory could apply to life on Enceladus. When applied to Earth, this suggests life originated from chemical, heat and tidal interactions beneath the seabed. NASA previously said Enceladus has all the ingredients for life, reported CNET, citing the space agency.
