That's more water than on Earth, which is only a thin layer on only part of its rocky surface.

I must say Alex, your voice is so calming. Add on to that the amazing content and this is easily the best underrated Science channel.

It should be pointed out that not all life requires atmospheric oxygen for growth such as anaerobes. So its possible that anaerobic life may be present in Ganymede (rather than on it). What is more important for life is liquid water, stable temperatures (tidal heating) and protection from radiation (which thick ice sheets can provide).

The key point made on the video though was that (unless the ocean is salty enough) the ocean is not in contact with the hot core of the planet. In the absence of sunlight, it is heat which provides the power for life in Earth's oceans. Would the tidal heating of just the water alone be enough to sustain life? I suspect not, given that life in our oceans, under the nearest conditions which we have, is only clustered around the hot vents on the ocean floor. Another problem with such a thick ice layer separating the ocean from the rocky and hot parts of the planet is that it is unlikely that the basic building blocks of life (which on Earth conveniently come up through the hot black smoker vents in the ocean floor) would be able to get to the ocean. Maybe there could be some on top of the ocean floor ice layer though, from ancient meteor impacts? If so though it is at the coldest part of the ocean, meaning that it would make it far far harder for life to have evolved there than on Earth. However, that said, if there is enough oceanic tidal heating to create currents which stir up sediment from above the ice layer, evolution may have found a way. If so though it is likely to have been a long time behind Earth's evolution. The less heat there is, the less activity life & thereby evolution can have.

This is a perfect illustration of how our larger planet formed, with the iron core from meteoric impact in its young age,to the rocky mantle which is the actual size of the planet, to the water covering from solidified steam from the cooling sphere, which made up the outer half of its total volume after being sealed in by ice from the frigid temperatures and thin atmosphere of outer space. Mind blowing. The difference is, the water covering our sphere was only about a mile in depth on average, and underwater lava flows and meteoric accumulation caused the compensatory adjustment of the rising land masses above the water.

Thanks for the video

Fun fact, @ 7:06 the general cause of tidal deformation is not the satellite's mass being pulled toward the direction of Jupiter. It's a result of the sum of all relative g vectors at the satellite's "poles" (2 opposite points on an axis containing center mass, axis perpendicular to the plane containing Jupiter and Ganymede) directed relatively inward, squishing the planet. That explains why satellite becomes deformed ("bulging") on both sides. Conditions would have to be quite extreme for "mass being pulled" effect to become dominant and barely noticable. Amazing video, keep them coming pls! ^_^

ty Ill check out Magellan TV

Great work

nice, thank you :)
