Default Jupiter image

This is mostly for those who own the book "Beyond: Visions of the Interplanetary Probes" (I hope I got the title right, as I own the book!).
Anyway, this is the most beatiful collection of images of our neighbors (and our own planet, no less) in space.
One thing struck me as odd. In the pictures showing the full view of Jupiter, the image looks inverted compared to others I've seen, including those online. I use the Great Red Spot as a reference.
In most images, the GRS is in the southern hemisphere of the planet. But in "Beyond" it appears in the northern hemisphere.
It also looks as if the image was turned upside down. I'm wondering if this is how Jupiter appears, or if it was a way of messing with our minds in showing this unfamilar view of the giant planet. I wonder if it also undermines the fact there is no up or down in space!
Opinions welcome!

I've never read that book, but in most telescopes objects appear inverted (upside down). I've never seen the GRS with my own 'scope before, but I'm guessing it'd probably appear in the 'northern' hemisphere.

The voyager etc images all showed the GRS in the southern hemisphere, so I'd say that is probably the 'right' way up - at least in the sense that we consider directions. Is the picture an artists conception or an actual photograph? If it's a photograph, what was it taken by?

with regards

North up, south up, it is still Jupiter:

In the book in question, they are ALL images from various spacecraft.
So, the picture is an actual photo (as far as spacecraft go).
The images of Jupiter are from Voyager 1 and 2, Galileo, and Cassini. All are oriented to show the GRS at the top of the photo. At least, all that show the whole planet. Most images show details in the atmosphere, as well as the moons.

Hmmm....I dunno. I'd guess that it's in the 'southern' hemisphere (with respect to Earth's) but I'm sure someone else here will give ya a better confirmation.

Of course, "north on top" is only an arbitrary convention, not a natural law... :wink:

true, so the question becomes, is it an "upside-down" image, or an inverted image?

And even "rightside up" images could have been inverted. Some by a telescope, some by the publisher. I've often seen photos of people that have been flipped left-to-right, probably just because the editor wanted them to be facing away from/towards the crease of the magazine. Sometimes even mountain ranges are reversed.
