You are needed!

Scientists are asking the public to identify a million galaxies. Apparently the human eye is better than computers for this job and astronomers say it would take them years to do this, so that's why they need us. Yesterday two thousand people logged on to this new site making it crash, but it's fine now. Looks fun.

Can i ask a question please

What if you are incorrect in some of your identification
Doesn't it mean that potentially a lot of incorrect information will be gathered ?

I have just done an hour on that site.

Bazile, They don't reveal their algorithms but since they let you take part as long as you get 8/15 correct in the test, then they must get multiple wrong classifications. I would presume/imagine they are doing it statistically and more than one person is being offered the same images to classify. It would then be classified as whatever the majority decide. Presumably they have run trials with students to find the optimum number needed to classify each image.

gen2 - that makes perfect sense
I'll have a go soon
