Brilliant, thanks. So how long before we start putting solar panels in close, direct orbit around the Sun?

Short answer: you can't. The Earth's rotation would make collecting that energy very unwieldy. Individual collectors could act like capacitors, but getting that power down to the planet continuously isn't really doable with any current technology.

You wouldn't beam energy directly from near-solar orbit to the surface of the Earth; you would relay it to orbiting receivers around the planet, which would in turn beam it to the surface, and reaching the night-side as well as day-side.

the second video says:

> the infrared data captured a faint aurora

when talking about aurora strength which variable is predominant: the magnetosphere, the atmosphere, or amount of solar radiation?

also, can anyone speak to the reason for the noisy instrument detecting those 3.45 micron wavelengths? why is the bottom edge so active?

“Saturn has a hexagon at the north pole,” said Bolton. “There is nothing on Jupiter that anywhere near resembles that. The largest planet in our solar system is truly unique. We have 36 more flybys to study just how unique it really is.” This is the first I've heard of Saturn's hexagon, very interesting: http://www.space.com/30608-mysterious-saturn-hexagon-explain...

Some threads I read on another site described it as perturbations of a periodic wave moving around the pole in a circle.. modeled something like this: http://www.wolframalpha.com/input/?i=plot+x%5E2+%2B+y%5E2+%3... ) or http://www.wolframalpha.com/input/?i=r+%3D+1+%2B+cos(6*theta...

Doesn't seem to hold up to a sensitivity analysis as much as one would expect given how long it has remained stable.

" other solar systems"

The answer is we don't. Unlike the other three gas giants in the Solar System we can't see Jupiter's pole clearly. So Jupiter is unique to our solar system, and we don't know much about the visual details of exoplanets.

Is Jupiter all gas or does it have any mass? It is hard for m kind to imagine a big ball of gas looking like a planet and going around the sun

Ignoring all the fascinating stuff about Jupiter, let me point out this gem: The download of six megabytes of data [...] took one-and-a-half days I sometimes like to scare kids by telling them about the time when I surfed the Internet with 14.4 kbit modem, but even that looks incredibly fast compared to the speed of interplanetary data transmission (back then, 6 MiB would have taken me about 2-2.5 hours). (NB that I…

It's also fascinating to think about how TCP is ineffective at that distance. https://en.wikipedia.org/wiki/Interplanetary_Internet is a good starting point to learn more.

That means when humans finally colonize Mars, there will be two FaceBooks, FB Mars and FB Earth, with any communication between them running at a lag.

I bet there will be AI research to create bots to act in "real time" on your behalf on the opposite planet. If the artificial agent can imitate your own actions and judgements, it would be a good way to surpass the speed of light. It will be necessary to build these agents because other interested parties could use the time lag to unfairly gain an advantage over you. The more we explore, the larger the time lag. With Jupyter it is 33-53 minutes. With Pluto it's 5h. The nearest star - 4 years. The Moon is at 1.3s.

You just gave me a great idea for a Halloween costume.

The last thing I need is a realtime Facebook now. I feel like I should build in a delay of ~1 week to everything I do.

Jupiter is almost all hydrogen. However, the bulk of that hydrogen is actually liquid. Its core has compressed the hydrogen so much that it's ionized and is essentially a metal.

It seriously sounds like you might have a notification addiction: you should try forcing yourself to check messages at most only a few times a day for a while to detox.

Yes. I world also like to see the delay randomized between 3 and 10 days so that nobody can tell what tempo you're replying at.
