ever try to find the bottom of a lake with deep silty bottom? I think it's quite possible that there is no real "horizon" between "atmosphere" and "crust\mantle" as the density could increase until distinquishing what was which is impossible - even if there is a core of elements similar to those on earth.

Yes, that's what I was thinking.

RAZD writes:

The only way for there to be a discontinuity is for there to be either (1) a change in material (like here) or (2) a change in phase of the material, a sudden collapse of molecules into a new form not known here.

That's something I hadn't specifically considered; are the constituent elements/compounds of Jupiter (and the other Jovian planets) believed to be essentially the same all the way down, or are there definite changes as you get deeper?

By "changes" I mean do the actual substances themselves change as you travel down through them, or are they pretty much the same right through and only change in their density as you go deeper?

Thanks for the help, by the way, RAZD.

not a clue. I haven't been there yet.

Re: life on other planets
Haw haw! Well, let me know when you do.

But seriously, haven't they dropped probes into Jupiter to test these things? I seem to recall something like that being done a while back. Memory's hazy, though. I might try and look it up.

Re: life on other planets
yes, but lost communication shortly after entry. they should try one that relaunches a "message bottle" back

Oh right. Was it destroyed or was there just too much interference from the atmosphere?

RAZD writes:

Message bottle? Hey, slow down, egghead!

Ok, I assume that's a detachment from the probe which acts as a signal booster, yes?

That would work assuming it was just an interference problem. Wouldn't help much, though, if the probe was destroyed.

EDIT: Sorry to keep bothering you, by the way. I just find this stuff interesting.

Re: life on other planets
could be a booster or just a return data carrier, getting high enough to send.

the have been thoughts to use something more like a helium balloon rather than a parachut to stay high longer.

I think they need a slow "descent into the maelstrom"

Probes due to be dropped on Jan 14, 2005 IIRC.

Ah, I see.

Wouldn't it be better to descend into a calmer location? Or are there simply no calm locations on Jupiter? Maybe just relatively calm? Or perhaps the "eye of the storm" is the calmest location.

Outstanding! Thanks for the info, jar!

How long does it actually take to get there? Has the probe been launched yet?

Thanks again, jar. This is greatly appreciated!

Re: life on other planets
Everything is currently orbiting Jupiter and functioning well so far. For more information on all of the Jupiter missions go to NASA and search on Jupiter and Saturn. You'll findd lots of information on their composition.

But I think I'm wrong on the date. The date I gave you is for the release of the Saturn probe.

Re: life on other planets
I don't think that's correct, there is no probe currently orbiting Jupiter that I know of. Cassini went by Jupiter a couple years ago, and is now exploring Saturn. Its functioning well as far as I know and will drop Huygens, a probe, onto Titan in January 2005.

Go down the Red Spot? May not be representative ...

ps NASA sites good advice.

Re: life on other planets
That's what I was saying. It is not the Jupiter mission but the Saturn one. The probe is meant for Titan. I was incorrect in first saying it was Jupiter.

But IIRC, at the end of the Galileo mission, just about a year ago, it plunged into Jupiter's atmosphere.

Re: life on other planets
yes, never heard much about it after that, what facts they gleaned from the event (especially that they hadn't already learned from Schumacher-Levy)

Jupiter
Do you think it is possible for life to evolve in the atmosphere of jupiter and how would it be detected?

Would it be a large red colony of methane cloud bacteria?
