I would've thought Uranus would be deeper...

This is Hacker News, not 4chan.

Jupiter is so cool. Fun fact, Jupiter’s Great Red Spot is a huge storm that has been raging for at least 188 years if not much longer. It also has a diameter about 2-3 times as wide as Earth’s. Jupiter also is believed to be a gravitational shield that protects us from asteroids and comets. Jupiter is also Home to some of the coolest Moons in our solar system, my favorites being Io, Europa, Callisto, and Ganymede (th…

One way I know I had an ok childhood was that when I found out the gas giants didn’t have a surface I could stand on, it was a notable and memorable low point

I think analogy breaks down.

There's probably not any light at the transition between the liquid and metal layers of hydrogen, the liquid layer is thousands of kilometers thick (the deepest ocean is ~11 km). And it's sort of hot. Not stove top pan hot, 10x hotter than that.

Oh and the pressure is a couple million times Earth surface pressure.

So... do astronomers truly have no idea why the 9 polar cyclones don't combine? I can't imagine what mechanism might prevent this.

There's an interesting video I've seen before showing it being recreated in a lab. I do not, however, know the origin or reasoning behind why it happens.

The renderings are amazing looking! It makes Jupiter looks like an evil planet.

Those aren't renderings, they are composite images made from photographs taken of Jupiter using an infrared camera on the Juno spacecraft.

Sometimes I wonder how different our world might be if it were the size of Jupiter but at the surface still had the same gravity we have now.

It could take days to download something from the other side of the planet. And probably a month of airplane travel just to get there.

Hey, neat! Jupiter almost has an octagon on it's north pole (and nearly a pentagonal version on it's south pole), similar to Saturn's northern polar hexagon! [0] https://en.wikipedia.org/wiki/Saturn's_hexagon [1] https://www.smbc-comics.com/index.php?id=1930

Well, that was mentioned in the article too.

Yes, and now you’ve mentioned that it was mentioned in the article. So here we are, mentioning things.

Latency would be higher, and might make phone calls a little awkward perhaps?, but it shouldn't make any longer to download a file. You might want to modify protocols so they send acknowledgements less often, or use larger packets perhaps.

Exactly this. It's always amazing to me how latency gets confused with bandwidth.
