Google-powered Bar-drawing Zoo2 offshoot
Once again we need your help with more detailed classifications of a
selection of galaxies.
We’ve made a sample of interesting galaxies from Galaxy Zoo2, most of
which have bar structures, and we would like you to measure the length
and thickness of the bars. Also we’d like you to check the shape of
the galaxy and tell us how the spiral arms and bars are linked.
We are also pioneering the use of the Google Maps interface for Galaxy
Zoo science, which allows us to perform tasks like drawing on
galaxies. Please note, that the bar drawing pages work best with

We’ve describe the our science
rationale: htp://www.icg.port.ac.uk/~hoyleb/bars/tutorial.php#s1 and there is a forum topic related to this page: http://www.galaxyzooforum.org/index.php?topic=276269.0
See you on the bar site!

A new project!! What fun!!
The page won’t even load for me.
I was willing, honest.
Read through the tutorial and attempted to provide the required input.
Found it most disconcerting that the controls had a distinct lag after being selected. Had no idea how to adjust the shape in any sensible way, loads of points seemed to get left behind and the curve bore no relation to the points anyway. Attempting to increase the magnification of the first galaxy presented lead to a display with only the ellipse visible and since my galaxy was too small to fit inside the ellipse, did that make it a good fit?
Couldn’t adjust the ellipse (for the reasons above) to match the second galaxy, so I gave up.
Not for the dumber of your zoo visitors obviously. 😦
Two years ago these ringed and barred galaxies were thought to be rare. We have found since then so many in SDSS that they are now common.
Try to persevere.
hi IC 1001,
I see from some forum threads that these problems are now fixed. I recommend using Firefox with the site, because Internet Explorer produces unwanted effects.
It seems you’re having a lot of trouble!
Could I recommend going over to the forum:
to see if your questions can be answered there.
If not, please post a note, and I’ll look into it.
I read the topic writer explaining what was the experience when he saw the glaxxy at night. that time was very interesting for the writer. writer had sed the pic. on the glaxxy website . this picture is very attractive and clear .
Cool! I’ve worked on it for a bit. Have a few galaxies in my bag.
great! Especially it works with firefox!!!
