|field_purpose_of_project=The main purpose is to understand how galaxies formed. According to the Galaxy Zoo team : {{Quotation |"Galaxies come in very different shapes and have very different properties. they may be large or small, old or young, red or blue, regular or confused, luminous or faint, dusty or gas-poor, rotating or static, round or disky, and they live either in splendid isolation or in clusters. In other words, the universe contains a very colourful and diverse zoo of galaxies. For almost a century, astronomers have been discussing how galaxies should be classified and how they relate to each other in an attempt to attack the big question of how galaxies form." }} | |field_purpose_of_project=The main purpose is to understand how galaxies formed.

The classification of images in Galaxy Zoo would help scientists to understand the structure of the universe and determine whether there is anything "fundamentally wrong" with existing galaxy models. | The classification of images in Galaxy Zoo would help scientists to understand the structure of the universe and determine whether there is anything "fundamentally wrong" with existing galaxy models. | ||

* Professor Michael Longo of the University of Michigan finds that there is a clear pattern of preferred spiral galaxy spins (or handedness) [[http://arxiv.org/abs/1104.2815 see article on http://arxiv.org]]. If the rotation of spiral galaxies is not random, it would force a major rethink of cosmology (potentially Nobel Prize implications).

|field_participant_task_description=Volunteers users have to work with images taken by the Sloan Digital Sky Survey program. They decide whether the galaxies are elliptical or spiral and report if they have features like having spiral arm pattern bar or have undergone transformations. Volunteers can also decide to discuss image wich will appear then on a community wall. | |field_participant_task_description=Volunteers users have to work with images taken by the Sloan Digital Sky Survey program.
