Description Galaxy Zoo is an online astronomy project which invites people to assist in the morphological classification of large numbers of galaxies. Purpose The main purpose is to understand how galaxies formed. According to the Galaxy Zoo team : “"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."” 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. ?

Tasks 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. Interaction with objects Volunteers don't manipule images, they just have to answer questions about it. However participants can add images to their favourite and present, comment, discuss their image to the community. Volunteer can experience a kind of particular relation with data. Interface

3 PROJECT DEFINITION


3.1 Subject

Natural sciences > Astronomy (space)

3.2 Description

Galaxy Zoo is an online astronomy project which invites people to assist in the morphological classification of large numbers of galaxies.

3.3 Purpose.

The main purpose is to understand how galaxies formed. According to the Galaxy Zoo team : “"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."” 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.

3.4 Research question.

Some research questions

  • Theorists believe that spiral galaxies can merge and become ellipticals and vice versa if they receive more gas or stars.
  • Professor Michael Longo of the University of Michigan finds that there is a clear pattern of preferred spiral galaxy spins (or handedness) 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). see forum discussion

4 ABOUT PARTICIPANT TASKS


4.1 Tasks 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.

4.2 Interaction with system objects.

Volunteers don't manipule images, they just have to answer questions about it. However participants can add images to their favourite and present, comment, discuss their image to the community. Volunteer can experience a kind of particular relation with data.
