GZOD: cosmic confetti

[JeanTate]

Budgieye, in her Galaxy Zoo Object of the Day, stardate 8th October, 2010, posted several examples of cosmic ray artifacts in Hubble Zoo images. Most times the raw images are cleaned of these artifacts before being made available for the zooites to classify; but, as is obvious from the above pair (originally posted by zooite zutopian), not always.

In looking at today's APOD, there are red dots throughout the photo.
I assume they are suns, but I can't imagine that they're red giants,
there too many and they're not big enough. Is this the result of a filter?

• • The Red Dot

George: How come this sweater is only 85 dollars?

Woman: (showing the dot) Oh, here. This is why.

George: What? I don't see anything.

Woman: See this red dot?

George: Oh yeah.

Jerry: Oh it's damaged. (grabbing the sweater)

Yes, another galaxy Zoo image by JeanTate!!!

Wow, what a group of galaxies. Those on the right are incredibly blue, but those on the left are much more reddish. If I had been responsible for classifying those galaxies, my first conclusion might have been that the red detector stopped working in the right half of the image! But maybe the red confetti prove that the red detector was doing just fine, and the lack of redness in the galaxies on the right was entirely the galaxies' own doing?

The confetti sure add a festive feeling. It's nice to see an image like this for once, but I'm sure glad that galaxy pictures don't normally look like that!
