Phoebe Pictures Released 123

EccentricAnomaly writes "NASA has begun to release some pictures from Cassini's Phoebe flyby last Friday. If you look at the thumbnail of this image or if you look at the right of these images, you can see a group of craters that look like a skull just south of the equator and something that looks like George Washington (wearing his wig) near the north pole. Come up with some good names for features, and you can submit your ideas to the IAU. There's a process for naming a newly discovered crater, fossa, or sulcus. By the way, the naming convention for Phoebe is people associated with Phoebe or the Greek islands."

      • Imagine two ice miners, working the surface of Saturn's moon Phoebe. The year is 2643. They are talking about the crater they are digging in: "Smelly Cat". They talk about all the possible permutations, the fact that cats can't live on the surface of Phoebe, the fact that if they could they wouldn't be detectable by smell, what sort of cat would live on Phoebe, exactly why the poor beast smells in the first place. Could the smelly cat not be an attribute of the cat, but instead be what the cat does? A cat that smells all day? They even wonder what a smelly cat is in French, and decide that it's probably a 'chat royale avec fromage'.

        But these poor souls have no idea that just over 500 years before them there was a completely inconsequential but highly amusing television show, where a song called "Smelly Cat" played a minor character definition role. The point of this story is that we MUST have a crater named smelly cat, just to fuck with people's minds.

      Not yet... The real wackos will be eagerly waiting for the pictures of monolith shaped objects, ideally on Iapetus.

      Not only is Iapetus one of the moons actually discovered by Cassini (in 1671), but it has one black hemisphere and one white hemisphere. It is thought that dust accumulated from Pheobe is responsible for the coating on the darker hemisphere. Intriguingly, there is also a small black dot in the middle of the white hemisphere, exactly as described in 2001 (the book, not the film)...

      • So did life imitate art or the other way round, i.e was the dot known when the book was written?
        • by Zocalo ( 252965 ) on Monday June 14, 2004 @09:21AM (#9419046) Homepage
          Life immitated art. The unusual colouration was known about for a long while - Cassini himself observed it when the moon seemed to "disappear" - and is a reason why Clark chose Iapetus for the location of the monolith. However, while the novel was written in the late 1960s, the anomaly in the pale surface was only detected by the Voyager flybys. There is a comment about the "black dot" in the foreward of one of the sequels, I forget which one, but Clark received a photo of the anomaly from NASA with the comment "Thinking of you..." or words to that effect.
        • In order for life to imitate art, someone had to see the art and imitate it. I didn't put the dot there, so who did?

          Life resembling art is either a coincidence or due to the art using designs similar to what happens in reality. In this case, the symmetry of a dot in the center can be due to several natural processes.

          • Yeah, but it sounds better to say it the way the grandparent did than:

            So, is that art imititing life, or did was the dot always there and just noticed after Clarke wrote about it in his book, making for a very strange coincidence that is nothing more than an amusing anecdote to talk about on slashdot?
            • I prefer:
              • Was the dot already known when Clarke wrote about it?
              • Did Clarke guess it might be there? (there might have been an oddity which could be explained by a dot, but in fiction he doesn't need to prove his explanation is the only one)
              • Did someone look closely for the dot because Clarke wrote about it?
              • Was the dot discovered later although nobody was looking for it?
              • Did someone fake the dot because Clarke wrote it was there?
              • Did someone create the dot on the surface because Clarke wrote it was there?

        Well, since the colour of Iapetus' dark hemisphere is a different hue than Phoebe's, that theory is in question. See Space.com's page on Iapetus [space.com].

      • NASA's recent observations of Phoebe seem to call that into doubt. Phoebe appears to be a block of ice covered by a dark layer of dust. In short, it seems that Phoebe is itself simply coated from some external source. The real question is, "where is this dust coming from?"
      • Dust on Iapetus (Score:5, Interesting)

        by Rhodnius ( 749829 ) on Monday June 14, 2004 @03:40PM (#9422929)
        The theory that Iapetus was darkened by dust from Phoebe is alluring, but doesn't really hold up to scrutiny. It looks logical when you see a drawing of the Saturn system, with the half-dark moon sitting next to the dark moon, but that's about where the plausibility ends.

        First, the moons are far, far apart. Phoebe orbits 5x farther from Saturn as Iapetus does - a difference on the order of 10 million km. Phoebe would have to be emitting a tremendous amount of dust for Iapetus to pick up any remotely visible amount of it.

        Second, their orbits are inclined approximately 160 degrees apart. Iapetus orbits almost in Saturn's equatorial plane; Phoebe is nowhere near it. There's no astrophysical reason for the dust to get into Saturn's equatorial plane and stay there waiting for Iapetus. (Saturn's rings remain compressed into the equatorial plane by tidal forces near the planet, but those forces become extremely weak that far out. Iapetus orbits 30x farther from Saturn than the outermost large ring, and tidal forces decrease with at least the square of distance.) The volume of space that would have to be dusted by Phoebe to visibly darken Iapetus is simply prohibitively large.

        Third, if Iapetus is darkened by dust, why not any of Saturn's other moons? OK, we don't yet know if Titan is, but the other moons should show some evidence of the same process, and they don't.

        Fourth, Iapetus isn't half-and-half black and white like a chessboard or that race in Star Trek. Voyager showed that the dark area is a roughly circular area, roughly centered on the leading orbital hemisphere, with a highly irregular border. And there are light spots within the dark area - not a single dot in the center, but a few separated irregular areas. It's a surface feature of the moon with lower albedo, not "this half is black."

        The dark area occupies a proportion of Iapetus's sphere similar to the proportion of the Pacific Ocean compared to Earth's sphere. Discounting the Velikovskyists, we're fairly sure that the Pacific Ocean was formed by Earthbound processes on our planet, so Iapetus's geological history could well have had something of similar scale.

        I doubt we'll ever know for sure until an Iapetus lander spacecraft, which isn't even remotely in NASA's future plans yet. Yes, something weird happened on Iapetus, but it wasn't dust from little Phoebe.
        • It's a surface feature of the moon with lower albedo, not "this half is black."

          It's as dark as lampblack. It's so dark that the 'black' side is as dark 'white' side at night. ...and it's almost impossible to find the Iapetus terminator as a result.

          Also, Phoebe has much more variation in color than previously thought, so it's still too early to conclude the Phoebe is not the source of the dark side on Iapetus... Computer models show that it is possible.
        • something weird happened on Iapetus, but it wasn't dust from little Phoebe.

          Maybe it was dust from Monica or Rachel?

        I always wonder how stupid people have to be if they believe they are really "naming" stars.

        Actually, I take that back. It's more of a Slashdot-we're-nerds sort of thinking to know offhand that they're bogus, but if you ever see one of those advertisements, they really seem legit: "Your star will be registered in the A.E.A.S.C. database" or whatever - that can mean "some excel file somewhere." They make users think they are officially naming the celestial body.
        You'd have just as much sucess with an ad "Name an orphan in Liberia after your sweetheart! It'll be registered in L.O.L. database!" - it'd have just as much "official-ness."
