So, the key point here, is its sort of pointless to post any movie numbers from pages that display the "Unusual Route" message. The system is lost by that time and the numbers don't correspond to images any more.

Nice lateral track with stardust visible

Post by dd »

In the upper left corner:

Too bad I had a stupid "you must have pushed the back button"-message: the particle is not on my official list ;-( But anyway there seems to be a lot of those...

Edit: I didn't think about this before but this nice example could be nothing more than a training sample :?

Oh, and first post ;-)

Hi Damien, and welcome!

I believe what you are seeing is "artifact" (dust, yes, from space, not likely). Notice how, when you focus further "down", the particle becomes blurred. This suggests that the particle resides right near the surface of the aerogel. Considering that the space dust was travelling 1,000's of MPH (or KPH, for that matter), such a short track for such a relatively huge particle is highly improbable (remember, it is highly unlikely that we'd be able to see the particle itself even if we could focus at that level - they're really tiny).

One way you might want to double-check yourself is to notice that the "track" should never really be out of focus no matter how deep you go - even if it's a lateral track, it would easily span the few microns of depth that we're revealing here.

Hopefully you found this helpful, but if any others have some further input (or something to counter my comments), please feel free! :D

Regards, and happy dusting!

I also found something like this:

And there might be another possibility - this might actually be a trace, but from a very tiny particle (we are looking for dust right?).

Yeah it does look very similar to the ones I found. The object doesn't come into focus until you are under the surface. I would vote that as a possible track.

This doesn't look like a track that we are all so familiar with from the test slides. However it is below the surface. Look in the upper left quadrant of slide 42208.

PS: a refrence grid would be nice :wink:

This is the hot topic. What are these? And should we be clicking them? No one knows.

Calibration videos classify those as tracks so I'd mark them. Of the 256 calibration videos I've viewed only 3 of them so far have had the mini tracks like you found. If these are in fact the tracks we are looking for I bet more calibration videos will start showing up with this type of track.

There's another one in that same movie in the middle right. They look like the kind of "real" tracks that have been cropping up, so click away, I say.

Tell me what you think about what I've found?

Post by barrett777 »

Hi Everyone,

I found a few interesting things last night, and I'm too excited to just sit and wait for someone to review it :)

Please tell me what you think about these:

http://stardustathome.ssl.berkeley.edu/ ... e_id=42029
This is the best one statistically, 8 agreements out of 15 views. It's faint, towards the middle, comes into focus around the lowest image.

http://stardustathome.ssl.berkeley.edu/ ... e_id=23734
If I didn't know better, I'd say it's a giant fiery meteorite!
But really, what is it?

http://stardustathome.ssl.berkeley.edu/ ... e_id=41844
I think I see a small track coming into focus towards the top-middle of the image.

Also, post any interesting things you've found as well?

I think your first and second are definitely real tracks. Your second one, sadly, is just a rather impressive chunk of aerogel sitting on the surface.

EDIT: On further viewing, your first one even has another track, near the top middle, just barely getting close to focusing at the bottom image. Your third one has three more along the right side: two near the bottom corner and one in the middle-ish. Nice finds. :D

Here are the ones I think I've found, but have no other agreements on them; they're quite small:

Movie 42362: Middle-left, and on further study, a faint one on the middle-right.
Movie 43213: This has a few: at the top and bottom of the large dark "mess", and two more to the left of that a ways.
Movie 41730: This one I'm surprised I found, and when i checked My Events later on, I thought it was a mistake, since it took me a while to see it again. The aerogel spot just at the bottom right edge begins to come into focus at the very top of the movie, and there is a tiny speck a little to the left and the very bottom that comes into focus near the end.
Movie 43642: A speck to the right of the middle, one or two frames from the bottom.
Movie 42763: This one is just beginning to be visible at the bottom of the movie, near the left edge around the middle.

http://stardustathome.ssl.berkeley.edu/ ... e_id=23734 just looks like light perfectly reflecting off the gel

I would agree that the other 2 are tracks though.

I've found a few potential tracks. The one that is the easiest to spot is

http://stardustathome.ssl.berkeley.edu/ ... e_id=41998

And these two have similar tracks
