The search for extraterrestrial life within our Solar System

[Grim Reaper 6]

Hello everyone, I would like to discuss the possibility of the existence of Extraterrestrial life within our solar system. I believe the possibility that Extraterrestrial life exists on the following moons. All of these moons have a very important attribute water which is the major building block of all carbon based life forms. It is believed that the following moons may hold some form of aquatic life or microbial life forms.

Do, you believe that extraterrestrial life could hypothetically exist on one or all of the following moons?

What, type of life forms would you expect to find in the oceans found on these moons?

""Enceladus (Saturn): A standout candidate. The NASA Enceladus page outlines how the Cassini spacecraft discovered hydrothermal vents and geysers spewing water, hydrogen, and organic molecules from its subsurface ocean directly into space.

Europa (Jupiter): Believed to have a massive global saltwater ocean beneath a thick, cracked icy crust. Active geology and tidal heating provide the energy to potentially sustain life. The NASA Europa Clippermission investigates this world's habitability.

Ganymede (Jupiter): The largest moon in the solar system. It is the only known moon with its own magnetic field, and it hides a layered saltwater ocean beneath its icy surface.

Callisto (Jupiter): Heavily cratered but geologically quiet, it likely holds the largest subsurface ocean of all. The ESA JUICE mission is currently en route to study Ganymede, Callisto, and Europa in depth.""
Thanks very much for your consideration, I hope that many of you will contribute to this thread by sharing your thoughts on the subject.

Yes, I do believe there is fauna and flora life existing in this star system called the Solar system by EA*RTH beings outside of this planet.

In the water environments I feel there are possible amphibious and plant like creatures.

In the dryer environments reptile like and or insectoids.

On some of SATURN and NEPTUNE unnamed moons where there is limited light reaching but still radiation from SOL reaching I think there is life also that is not primarily dependent on light energy.

In the asteroid belt region it feels like artificial or synthetic intelligence could be sustained there that can monitor non-artificial/synthetic life development for NHI outside this star system...

There also may be more energy or electrical non-biological life and or intelligence existing within blackholes that only a selected few alien groups may have the abilities and technology to detect.

Thanks for your comments, some of what you said is over my head. However, your comments concerning Saturns and Jupiters moons I certainly agree with based upon scientific evidence that points in that direction. Since, any life on those moons is located beneath an ice covered surface sun light would not be the energy source that allows life to exist.

Most likely any existing life would be centered around volcanic black smoker vents like those on earth. The heat generated would allow life to exist, along with powering the ecosystem and the chemicals being released would give that life nourishment. This is how extremophile life forums exist in our oceans here on earth.

Again thanks for your post

Everyone is thinking Earth life on other worlds. Why?

Why would it not be possible for plasma based lifeforms to live on or in the Sun? They would not even see the planets as possible areas of life. Just cold dark rocks to be avoided.

Why would it not be possible for energy beings to live in the almost constant lightning in the gas giants? Those planets all have a lot of radio noise coming from those electrical storms. Or is it something else?

And about the gas giants. What about the possibility of jellyfish like lifeforms feeding on the chemicals in their gasses? Their surface density barely noticable above the gas they float in. 

The moons of the gas giants would be the place to look first because we might even be able to recognize what we find as life.

Considering what happened in Chernobyl, where some fungus adapted to use radiation instead sunlight, we also should consider radiation as an energy source, so even places without light or thermal energy could have some kind of life.

To me, the most important is if life ever existed, as judging by what we see on Earth, once life gets a chance to exist it adapts to whatever changes happen and keeps on existing. For example, I wouldn't be surprised if we would find life in underground tunnels on Mars, where the higher temperatures and air pressure may allow the existence of liquid water.

So, I suppose it's possible that any of those moons with oceans have some kind of life in them, we just have to be prepared to find them.

Thanks very much for comments. I am aware of the Fungus that was discovered at Chernobyl. These black, mold-like fungi uses the pigment melanin to absorb dangerous gamma radiation and convert it into chemical energy. Like you said above once life begins it will adapt to survive in almost any environment.

For any carbon based life form, water is the key to its beginning and for its survival. In 2024, the NASA’s Europa Clipper mission was launched, it is going to arrive at Europa in 2030. This spacecraft has the instrumentation to determine once and for all if Europa has the necessary environment to support life.

Hopefully, this mission will finally answer the important question everyone is wondering is there extraterrestrial life in our solar system. Only time will time and personally I am like a kid in a candy store, 2030 can't get here fast enough.

Oh, and by the way, how do you give someone a Like for a comment they made. I can't find the like button.

Thanks very much for your post, and for providing this wonderful site..

Define life.They have found bacteria in space and on Mars.

Define life.They have found bacteria in space and on Mars.

My understanding is that all we have found is potential biosignatures that may indicate past microbial life.

but no confirmation yet
