I’m going to go with no, not possible. Never mind the miles of ice it’s the radiation from Jupiter that makes me believe it’s a sterile moon. The radiation coming from Jupiter is just unimaginable. Fun fact? When you turn the dial on and radio that static noise you hear is coming from Jupiters magnetic belts a radiation belts. Jupiter is the most deadly emitter of radiation in our solar system. So that makes me believe it’s inhospitable for life to exist anywhere near Jupiter

Water is incredibly good at radiation shielding though, and even though ice is slightly worse, it's still great for it. And we're talking potentially dozens of miles of ice here.

Not at the levels Jupiter is cranking out! You have a microwave right? If you’re in a big bowl of water and in a giant microwave what’s going to happen over billions of years. Jupiter has the deadliest radiation in our solar system. Fact! So you going to try and understand what that means. And then imagine a tiny moon right up Jupiters ass getting blasted relentlessly for all of time.

>To reduce typical gamma rays by a factor of a billion, according to the American Nuclear Society, thicknesses of shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead.

Citation. Europa's radiation level on the surface is 1800x what the average person would experience on Earth annually, in a day. Radiation level then is = (1800)(365)x the amount a person would receive on Earth. Europa's surface experiences 657,000x the amount of radiation that Earth receives at sea level.

Okay. To reduce the amount of radiation received by a factor 1x10^9 would require 13.8 feet of water. 13.8 feet of water would be more than sufficient to block 657,000x Earth's radiation and get it to liveable levels.

Of course, that's gamma radiation, not decimetric radiation. The radiation from Jupiter is between 3cm and 3m in addition to the gamma radiation. Microwave to infrared ranges. I think a few miles of ice is enough to block this.

I’m not going to disagree with you on this, all I’m saying is Europa is in the most inhospitable position in our solar system. We as humans could never be able to shield ourselves from the radiation to even be able to find a way to investigate Europa. I subscribe to the theory of panspermia and it blocks me from seeing a way life could have existed in the most inhospitable place in our solar system.

You have a source for that radio static fact? If it were true, wouldn't that mean that the noise would go away for half of each day when the earth is between the observer and jupiter?

What’s coming from Jupiter is so massive it’s all encompassing of the earth. But you have to have a better grasp of the stratosphere to understand how something like this can’t be shielded from the earth not facing Jupiter. Have you ever seen how an EMP detonated in the atmosphere over say New York would race around the planet in all directions and effect the opposite side of the planet. You can fact check the static thang yourself if it’s something you have questions about. I’ve just given you an accepted fact of the cause of radio static. The technical reasons are complicated and you have to try to find explanations you can grasp that are more in depth than I have time to explain. But please do look into this and let me know what you think. Just saying it’s also an excepted fact Jupiter has the deadliest radiation in our solar system. Please don’t believe me, look up what I’m saying yourself. You gots google!

Obviously I researched before I commented. I'm not going to call someone out on something I'm not confident on.

The primary source of radio static is artificial (other electronic devices in the environment, as well as heat from the radio itself). The natural component (atmospheric noise) is mostly a result of lightning. The cosmic component is mostly solar activity with a small component coming from the Galactic core, the Cosmic Microwave Background and other extragalactic events (Source 1, Source 2).

While Jupiter does emit some radiation that's useful in radio astronomy, it makes up a negligible component of the environmental noise that the average radio picks up.

Translation: You made it up.

You should follow your own advice and use Google before you spread misinformation.

I wish i was creative enough to come up with shit like this! I’ve seen articles and it was years ago. I’m looking but honestly I don’t have the imagination to create something like this
