I have a feeling someone was playing with FOV...

Yeah, there's that. I need more, though.

Damn. This was uncomfortably opportunistic. Sorry Watsisname.


Haha, that's the fun thing with this game. smile

Also i guess it was to difficult to see but this shot was taken underwater.


Wow, really? I'd never have guessed that.

DIS7RICT, those are stars. One blue, two red. There's another star off-frame, to the right. And that is all that can be deduced from this image. This is a deduction game, not a guessing game.

Also, it wasn't your turn. It's HarbingerDawn's turn. I asked you to please only post something once you got one right. You decided to ignore me.

So I'm now asking everybody to please ignore DIS7RICT's post. It isn't part of the challenge. We are still waiting for HD.


Wow, so mean, i come back after 3 days and see this. You could have used mine instead of yourself going again. I'm sorry, but I didn't read your post properly I thought it said "as soon as someone wins a challenge" not if I won a challenge. I didn't ignore you at all, I just made an honest mistake.

It isn't a guessing game if you had half a brain, Spacer figured it out first try apart from the color of the hidden star. The blue star is obviously closer and orbiting the white star (It's obvious it's a white star, the shine is white) since the blue shine is the dominant shine in the picture over the two red ones. The red ones are obviously orbiting each other because they cannot look like that if they weren't. Sorry for trying to participate and have fun, just ignore this post please, a PM will do.

I probably shouldn't get involved in this, but I am going to anyways.

Quote JCandeias ()
After you win one challenge, yes.


There is a distinct difference between the two. I don't get how you mistook the latter for the first.

If he said your picture isn't proper(there is some things you have to guess, not deduce) then why in the world would he use it?

Are you kidding me? I am pretty sure no one sees this white star you are talking about, unless you mean the one on the right, which I doubt since you say that the blue one is orbiting the white one. And why are we honestly supposed to know the orbits of the stars from the picture?

DIS7RICT, I'm not going to go into an argument with you about this. This game is only a fun and working game if people play by the rules, and everyone saw what happened here and why I did what I did. Let's move on, shall we?

There's an image up to get information from, so let's do it. It's a toughie, I know, but it's one of those cases where as soon as you get the geometry of it straightened up, it becomes quite clear.

Ummm... There is a gas giant in the foreground and what seems like a desert with a dense atmosphere in the background.

Nope. That isn't right.

Allrighty, you guys seem to need a hint. So here's two.

First: there's only one light source here.

Second: Occam's razor is your friend.

There are two relatively large bodies with one most definitely being a gas giant. The closer ringed body is likely gravitationally (based on barely being able to see the curvature of the large body) bound to the presumed gas giant. Albeit this is a relatively wide orbit making the smaller body tilted relative to the main body. Then the light source is probably an orange-yellow star (k-G) but, this is difficult to discern due the the atmospheric colors of the bodies and potentially light orange rings.

Donatelo200, you are close, really close, but not quite there yet. Specifically, there's one thing you say is likely but can state for sure due to how and what is illuminated by the single light source I hinted about (and ulterior reflections), and there's one thing you say that you can see is not true by the plane of the rings and, again, by the lighting.

Also, there are hints that show you precisely where the light source is, and you can limit possibilities on the types of bodies those are (yes, one is a gas giant), but you can miss this last bit, since the image is open to several interpretations.

Well, since it's been 2 days, I'll give it to Donatelo200, for being by far the one who got closer and tell you how this scene works.

We have three main areas: at the top left, there's a black area with a few dots: obviously free space with background stars and maybe other planets and/or moons. At the bottom left, there's another, solid, black area; at the right there's a vast dark red area, which is partially overlapped by the body at the bottom right and cut in half by rings. The curvatures separating these main areas show that the main body is the one at the right, and the ringed one is a moon.

Since I told you there's only one light source, it's clear that the star, which is behind the moon (you can see that by the shadow the moon sheds on the rings behind it), sheds its light on its atmosphere (making it glow backwards in an effect known as backscattering) and surface, and then a part of it is reflected towards the planet, lighting its night side.

So we can now say for sure that we have a gas giant with a large moon in an orbit close enough to light significantly its night side.

We can also see by the rings that we are looking at the scene from below the equator. So there's probably no tilt in the moon's orbit (which is where Donatelo200 got it wrong) -- we're just seing very high latitudes in the gas giant, pretty close to the pole.

I don't remember anymore what kind of star this was, but I think it was a dim orange dwarf (or maybe a luminous M star). From reflected light alone it's not easy to determine that, especially if all you see are very thin slivers of it, and Donatelo200's guess was a good one. You can't say what kind of moon this was either -- apart from being large enough to have a significant atmosphere, which could mean terra, oceania, desert, titan or even ice world -- but I can tell you it's a titan.

Fun, eh? wink

Go ahead, donatello. Post a pic.

Ah nice that was a good one. This probably isn't nearly as challenging but here you go.

terra with life that orbit brown dwarf, there is yellow star far away (the stars orbit each another) and the real planet brightness is
off?

A terra moon with life orbits a brown gas giant and a yellow-white star and the giants light is reflected on the surface?
