Nice. I see you squeezed Mars, Pluto and Charon in for comparison as well as the Earth and the Moon. Just to be perfect you could find a place to put Ceres in for comparison as well. smile.gif

Ohhhh nice! smile.gif Would you consider releasing these under public license so that they can be added to the Wikipedia?

Well, considering several of these images are from Welcome to the Planets, including several of what appear to be Tayfun Oner's images, I think the copyright issues are a bit deeper.

Tayfun Oner? Ugh, copyrighting these probe images is so ludicrously silly anyway. I just don't get it. oh well.

To me, it matters in two ways. First, I have used it on more occasions than I can count to stop anomalists from using my images. Secondly, if someone else claims to have processed them. If they are used on a non-anomalist site without credit, I don't complain, but when someone else claims to process them, that makes me angry.

If this post is deemed not on topic for the thread, I pre-emptively accept your gentle rebuke.

What of Jupiters smallest possible satellites?

I have been toying with an idea, if it is of no consequence, let me know.

After comet Shoemaker-Levi was 'zorched' into Jupiters atmosphere, I wondered about the 'tail'. Or the tail of any other 'cometary' body orbiting Jupiter. Would the tail materials manifest themselves similarly to a meteoroid stream in orbit around the sun, but instead around Jupiter?

Granted such a 'swarm' would probably not stay collimated very well for very long, and I suspect solar radiation pressure and gravitational perturbations would 'flush' them out of the system fairly quickly.

However, as we saw, recently, comets might happen by to 'restock the shelves'.

Are these possible swarms of tiny moonlets orbiting Jupiter of any import?

Well, not having any appreciable atmospheres around any satellites of Jupiter rules out any naked eye confirmation by eventual astronauts there. But if a mechanism is found that keeps these streams in any way concentrated any where, such places may not be where we would want a space craft to traverse at high speed. Would a stream interact with the magnetosphere of Jupiter, perhaps characteristic changes of radio emissions of Jupiter might result.

But perhaps a spacecraft might view them via scatterring effects on light or perhaps in a way analagous to seeing zodiacal light.

THX tedstryk,
for taking away all the fun.
All Pics have been NASA / JPL Pictures.
Whats Tayfun Oner anyway, never heard of it.

Anyway pics are edited out.

That's a little unfair, and uncalled for. You could have spent 15 seconds on Google, like I just did, and found out who Tayfun Oner is. I bet if you asked him his permission to use his images, he would be more than happy to oblige with appropriate credit. How would you feel if someone did the same to you? Not too happy I imagine, looking at post #1.

Let me get this straight. You made a bunch of copyright threats after taking a bunch of processed images from the internet without tracing their origins, and I ruined the fun? rolleyes.gif

Just a thought...
Maybe you should make agreement with "spaceffm":

-He should delete all his copyrighting nonsence from his posts and in return you return his modified posts back...

I don't care much about those images , but I know it is not good to lose a member...

BTW.
I didn't meen to be mesing with your administration tedstryk...

huh.gif
You can just ignore this anyway...

Yeah -- insisting you're in the clear because you took images "from Google" is like a cop asking a robber where he got his loot, and the robber saying "I got it from the road." No, he didn't -- the road took him somewhere, where he then stole something.

Google takes you to websites. At many websites, there are copyrighted materials on display. You can no more just lift that copyrighted material and use it for your own purposes (with no attribution) than you can walk in a store and just take what you want without paying.

It's a good point to remember -- just because something is displayed on a website doesn't mean you're free to use it for whatever purpose. Until the copyright laws are changed, anyway.

It seems odd to me too to copyright something as simple as putting publically-available pictures of planets and moons together.. What if I then make my own such mosaic, am I breaking your copyright? It's like copyrighting a drawing of a stick figure - I doubt whatever court handles copyrights would support either one.

I am a bit confused Toma B...how did I modify his posts? I am not a moderator.
