Not nearly as deep as your mom.

Not as deep as Hot-Topic goths.

Like the sun, Jupiter is scary in both size and capability and must be destroyed.

"We knew it lasted a long time, but we didn't know how deep or how it really worked," Bolton said in the press conference.

It's 10,000 miles wide and 300 miles deep, still pretty pancake shaped.  300 miles isn't deep by Jupiter standards.

So do you think that when the spot finally vanishes there will be an uprising of spot deniers?
 
2021-10-29 1:50:14 PM  
Are we not doing phrasing anymore?

I would love to see them go to Jupiter and March around with signs.

I just thought of something - if Jupiter is a "gas giant" - where does the planet stop & the atmosphere begin?
(It's probabily  not very clean delineation).
At what depth does the Big Red Spot (BRS) stop being a cyclone & starts to become a volcanic upwelling?
 
2021-10-29 2:33:55 PM  
As if we already don't know this.
 
2021-10-29 2:37:02 PM  
Oh yea, well Uranus is deep, too, Subs!

It's not a stupid question, because it's nearly impossible to fully imagine the conditions down there... insane pressures and temperatures not far shy of the conditions reqiured to ignite nuclear fusion.

It doesn't. Jupiter is a gas giant so there's no surface beneath the atmosphere. This video has a longer visual explanation.

Jupiter has no volcanism because, again, there's no surface.

Hmmm. No exhaust port that we can shoot a Proton Missile at.

Tricky...

Exactly. This is why Jupiter has been called a failed star and actually that is a major plot point of the sequel to 2001:  space odyssey in the 2010 book/film.

Except that isn't really accurate. Jupiter lack the mass necessary to ignite a runaway nuclear reaction. Jupiter would need to add 13 times its own mass to become a brown dwarf star.

Which is far more than Jupiter, all the other planets, asteroids, etc. combined.

Thanks. That was interesting.

/still want to look deeper into this "metallic hydrogen" thingie.

Joke aside, watching the posted video on the planet and hearing that it's mostly hydrogen, I kept thinking "If I was in NASA I'd equip the explorer probes with a small unit that has one purpose, light a (self-sufficient) flare as the probe finally fell into the atmosphere and hit that hydrogen.

/it will be like a cosmic fart ignition
//the above slashie is to respond to any question of "why would you do that".
///not saying it's a sane thing to do (nor that I've actually lit farts, because I've seen what happens with those), but can you imagine what would happen if we lit that planets? Some amazing fireworks, a huge heat blast, followed by slow building of heat as the blast pushes us into the sun. So...who's with me??

It wouldn't work. Remember that Jupiter's upper atmosphere has lightning in the clouds, but because there's no free oxygen, the lightning can't set the hydrogen on fire. You need oxygen as a catalyst to ignite an explosion.

Flourine would work in a pinch. I mention it only for completeness. And also, I'm a smartass.

Jupiter will implode and Europa will be the next Earth. Our galaxy just recycles itself over time. Like new flowers every season.

The Juno pictures have been eye wateringly beautiful.

Dude, the great red spot was created on a bathtub on a soundstage at ILM and the gumnint is making wut thurr 'rona vckses outta this.
