Not sure which forum to post this to but just got the alumni magazine from Johns Hopkins University, Zanvyl Krieger School of Arts and Science. There is a FABULOUS article in there about how amateurs are helping professionals by identifying the types of galaxies seen in the Sloan Digital Sky Survey. One Dutch amateur astronomer noticed an unusual blue blob in one of the pictures and the professionals couldn't identify it so it's now been called "Hanny's Voorwoop" (Dutch for object.) It seems the primary purpose of the site is to go through the tremendous amount of data collected by Sloan and then catagorize the types of galaxies. Another search object was to look for rare blue elliptical galaxies. Anyway, there's a lot more to be done. All 118,000 volunteers are listed as co-authors on every paper published by including a link to a site with all their names. Seems like this might be of interest to some of the folks on this site. Please check it out: www.galaxyzoo.com

PS Mods please feel free to move this to a forum where it will get the most exposure. Thanks!

Sorry had the wrong site address:
http://www.galaxyzoo.org
Just signed up myself. There's a great tutorial in how to identify various types of galaxies. Its kind of addictive and fun.

Very cool website it seems a good idea but i would have thought theyd be able to write a program to classify galaxies with at least as good an accuracy as an amatuer.

It seems that humans are better at recognizing patterns better than computer programs but it also seems that humans also introduce their own bias as to the direction of rotation of galaxies. This is according to an article which appeared in Universe Today. Here is the link to the article Link Universe Today
I have been considering joining in the classification process. Cool!

Yes, they did address that in the article. They showed people mirror reversed images of the same galaxy and still people saw more countercloclwise galaxies.
I signed up for it. There's a great tutorial and I thought it would hone my observing skills while I make a small contribution to science.

Good project for amateur astronomers to take part in if they have the time to devote to it.

Awesome link! I just signed up and passed the tutorial test, I did about 40 already. No mergers yet, mostly distant ellipticals with some nice sprials and edge on sprials

Actually what do you guys think of this one? I put just elliptical, it appears the other 3 are close though. Possibly on collision course or going the other way?
