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

I think that's the fault of the infrared thing.

Infrared is by definition not what you would think of as a color. The colors in that picture are false, and a stylistic choice made during the rendering process. It would be just as accurate to use shades of blue and make it look icy. Perhaps more accurate as the upper atmosphere portrayed here is very, very cold.

One thing that might not be related but I found fascinating is that Jupiter is “木星” in Chinese, where “木” means wooden. The first time “木星” was mentioned in Chinese literature was in 东汉, year 25 - year 220 (around 1800 years ago). So Chinese people back then thought the planet was made of wood! And as a child, this planet has the name easiest to remember, because it looks exactly like a wooden ball. Edit: I digged de…

Not an interesting coincidence. Jupiter is hot but Mars gets named fire. Mercury looks like rock (thin atmosphere) but Saturn get called rock. You could find some reason to make almost any naming seem like a coincidence.

you must be fun at parties

And in these 5 planets and associated elements https://en.wikipedia.org/wiki/Wu_Xing rooted a large number of traditional beliefs: Feng Shui, Traditional Chinese Medicine, Martial Arts.

And arguably stunted progression from them. But that's getting off topic.

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.

I wonder if it would be possible for such a planet to exist and be habitable. Obviously it would have to be far less dense than Earth (or Jupiter); I'm guessing gravity would therefore compact it to a smaller size, unless maybe it was made out of some kind of lattice structure?

Better question might be what's the largest feasible (or likely) potentially habitable planet with earth-like gravity.

>And probably a month of airplane travel just to get there. Space travel would probably be more advanced by now.

It would be drastically harder to get out of the gravity well on the planet. Even if the strength of gravity at the surface was the same as Earth’s, the field would be stronger farther out than Earth’s —- 11x as much due to the geometry. It would take 11x more energy to escape the planet, though low orbit would be practically the same difficulty.

Assuming the existance of something like early human hunter-gatherers, if the earth were the size of Jupiter, we would not have transitioned to living in cities yet. There would be no downloading.

Earlier quoted context omitted.

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

What word would you use for composite false-color images produced by a computer if not "renderings"?

It really depends on how you define picture. I guess you could argue that it is still a picture in the sense that it is captured using an array of sensors that are sensitive to some electromagnetic waves.

edit: Wikipedia defines photography as "the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material [...]

It could fit

computer "renderings" has a very specific meaning, creating images from 2D or 3D models.

I would call this a 'composite image.'

Isn't it pointless to ask why a chaotic turbulent system ended up this particular way? The author keeps repeating this question (or stating "nobody knows"), as if there's some fundamental and interesting answer to it.

Mars at least probably isn't a coincidence, in terms of the element assigned, since it's visibly red to the naked eye.
