Last report was Jupiter's Great Red Spot was shrinking.

It's not only shrinking it also gets higher.
And Jupiters (and again my memory play tricks with me) Jupiter and some of its moons have the same we have here on earth. A things which makes it possible to watch polarlight
The satellite Juno's investing of Jupiter have shown disturbance of this electric magnetic thing.

One of the interesting things revealed by the probes Cassini and New Horizons was the very high radiation encountered around Jupiter and Saturn. Gravity and internal pressures was also considerably higher with an incredibly high gravitational field being generated.
Quote : The subsequent and far more technologically advanced Voyager (https://en.wikipedia.org/wiki/Voyager_program) spacecraft had to be redesigned to cope with the radiation levels. Over the eight years the Galileo spacecraft orbited the planet, the probe's radiation dose far exceeded its design specifications, and its systems failed on several occasions. The spacecraft's gyroscopes (https://en.wikipedia.org/wiki/Gyroscope) often exhibited increased errors, and electrical arcs (https://en.wikipedia.org/wiki/Electric_arc) sometimes occurred between its rotating and non-rotating parts, causing it to enter safe mode (https://en.wikipedia.org/wiki/Safe_mode_(spacecraft)), which led to total loss of the data from the 16th, 18th and 33rd orbits. The radiation also caused phase shifts in Galileo's ultra-stable quartz oscillator (https://en.wikipedia.org/wiki/Crystal_oscillator).

The other interesting aspect is the moons like Europa have their own heat source caused by a slightly elliptical orbit around Jupiter which in turn creates varying pulls, resulting in friction.

I'll see if I can some of my old travel slides from my last vacation there... :03: :D ...

I knew you were weird vienna you don't have to prove it :D
You know good and well that the rest of us came from Mars :yep:
Personally, I think this is a good thread. IMO, we pay wayyy too much attention to Uranus. :O::yep:
Beside history, Space/the Univers is something that can get me forget important things.
My eyes are glued to the tv-screen when there are program about the univers.

Jupiter is also a flat disc just like Earth.
Galileo discovered the four largest moons of Jupiter (Europa, Io, Callisto and Ganymede). He devised a method to determine one's longitude on Earth by timing the disappearance of these moons behind the planet.
Unfortunately, this was impossible to do on a moving ship and so was only really useful on land. But, apparently the method was used by Cassini and Jean Picard to produce a new map of France.

In the 80's, thanks to Jack Horkheimer, I learned that Jupiter would be at a closer proximity to earth and a good time for viewing.
So I dusted off my cheap refracting telescope and despite the light pollution, managed to find Jupiter and saw, with my very own eyes four of Jupiter's moons.
:o:o:o:o
Now, I had grown up looking at wonderful images of our planets, including Jupiter. Saw the great images from the big telescopes. Very cool stuff.
But when I was able to see, for myself, these four moons, I was truly awestruck. I could only imagine that this was how early astronomers may have felt with their crappy refracting telescopes that represented, for them, the state of the art in telescopes.
Sure I was a couple hundred years late, but on that one evening in Omaha Nebraska, I saw them. Me, a nobody, saw those four moons.... with my own eyes! They exist!
It was an unforgettable experience for me that ranked pretty high on my personal cool-o-meter. :up:
Thanks Jack :salute:

How right you are :yep:
Little more interesting stuff
The combined data suggest deep water-rich clouds, rising convective towers of moist air (16 times as tall as the tallest earthly thunderheads), and clear regions around them, caused in their view by the downwelling of drier air from the convective towers.

Walking at an average speed of 3.5 mph for about 60 miles a day it would take you 19,000 years to get to Jupiter from Earth.

If you weigh 100lbs on earth you would weigh 200lbs on Jupiter :yep:

Good God, the lockdown has finally gotten you... :03: :D

Take the bus, it's quicker.

Wait until Jupiter's orbital position is on the other side, then it will be a down hill walk.
You know
Each journey starts with the first step.
So if you expecting living forever and have enough time, then take the first step of billions.

Plutonium is named after the (dwarf)planet pluto .
Neptune also has an element named after it . Neptunium .
Unfortunately nothing named after Jupiter except the robinsons spaceship .

I beg your pardon :hmmm:
Jupiter ( Latin: Iuppiter) is the king of the gods in Roman mythology. He was the god of the sky and thunder.
He is known as Zeus in Greek mythology.
His brother's name was Pluto and his sister was Ceres
Not one to mess with for sure
