The Scientists from England have been calling for Online Volunteers to help them classify the Galaxies, through the pictures, into Spiral or Eliptical and note tag it.
They have snaped about 1 million photos of different galaxies through Digital Camera attached to a Space telescope at New Mexico.
For scientist alone to work on the task could take years, so they estimate the help of about 10000 – 20000 volunteers online which could help finish the classification in a matter of few months.
One can simply log-on to http://www.galaxyzoo.org/ , complete the tutorial and go ahead.
Each picture will be multi-verified to omit the error margins or any pranks.
