Pluto does look a bit like a choc+vanilla ice cream that was left out of the freezer
for too long (or a planet-wide experiment at cappuccino making, take your pick)

NASA PR is doing a mess. Released the same inset (flipped) in two different locations.

Compare this:

From what I understand, the correct one is the first one.

NASA PR is not producing the images. What you're seeing is probably the result of pressure to release the images as fast as possible.

People complain when releases are delayed. People complain when they're not. There's just no pleasing some people.

Question about slightly older Pluto images. Pluto is noted in these glass plates from Tombaugh's discovery in 1930. What is (are) the other item(s) highlighted in red?

Here's a crude blinking GIF:

edit: deleted. I pay little attention some times.

Ok, rtphokie, a more studied answer this time. Strangely, the object appears to be the same in both frames, so I would assume not dust (though it has a peculiar shape). It appears to be going 90 degrees to the ecliptic. in this image. I don't see anything registering on Stellarium. Interesting. Hope to see a resolution to this as well.

Also just noticed a few other moving dots. Pluto of course, near the middle in the ellipse.

This is a discussion better placed in its own thread though.

Apparently, if instead of a blink comparator, Mr. Tombaugh had used a stereo comparator (where each of the two plates is projected to a separate eye), any slow-moving objects would have been immediately obvious as a dot hovering above (or below) the flat plane of the fixed stars. Not sure how it would handle objects moving at a near right angle, like the second object pointed out above. I believe the individual plates would be slowly rotated through a 180 degree half-turn, but I'm not certain about that. This method was widely adopted after the discovery of Pluto because it was far easier to spot slow-moving objects using this method than with a blink comparator.

rtpholke, that was probably an asteroid. Recall that Tombaugh was specifically searching for objects moving at a slow speed, which would normally indicate that it was a large distance from the sun.

Well, that's not me. If they're not delayed, better for me, I can see them earlier. If they are delayed, again better for me, the scientists will have more time to understand everything and I'll have my questions answered earlier.

Yeah. We have to keep in mind that the press release images are just that - and they're not meant for the kind of analysis many of us do here. (We've seen some bizarre stuff with the Dawn press release images, too.) We may have to wait for the jpegs at the New Horizons SOC site, and better still for the eventual downlink and release of the raws.

Push the gamma on one of those press release images too far and you never know what you may find...

Makes sense, thanks

We can rule out another TNO, given it is not moving in the same general retrograde direction as Pluto. MBAs and NEOs can also be ruled out for similar reasons. Knowing how thorough Tombaugh was with his survey, he wouldn't have overlooked something of that magnitude. The non-symmetrical appearance in both images suggests they were specks of dirt on the plates when they were eventually scanned.

I know what you mean. Opened the 'false colour' image in Photoshop and it still had the 'guide lines' smile.gif

I wouldn't think it is an asteroid, since they move the same apparent distance in hours when Pluto takes months.

Depends almost entirely on the distance. NEOs at their closest can whiz by VERY quickly from our perspective, main belt asteroids not so fast.

I don't recall the interval between the two Pluto discovery photographs, but I'm pretty sure it was hours or at most a couple of days, not months. Those pics have an extremely small field of view.
