Galaxy Zoo

Galaxies, made up of billions of stars like our Sun, are the beacons that light up the structure of even the most distant regions in space. Not all galaxies are alike, however. They 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. Galaxy Zoo (Lintott et al. 2008, 2011) pioneered a novel method for performing large-scale visual classifications of survey datasets. This webpage allows anyone to download the resulting GZ classifications of galaxies in the project.

星系，由数十亿颗类似太阳的恒星组成，是照亮宇宙最遥远区域结构的灯塔。然而，并非所有星系均相同。它们呈现出极为多样的形态和特性；或大或小，或老或幼，或红或蓝，或规则或混乱，或明亮或昏暗，或尘埃丰富或气体贫乏，或旋转或静止，或圆或盘状，且它们或独立辉煌，或群聚而生。换言之，宇宙中存在着一个色彩斑斓、形态各异的星系动物园。近一个世纪以来，天文学家们一直在探讨星系应该如何分类以及它们之间如何相互关联，以期解答星系形成这一重大课题。Galaxy Zoo（Lintott et al. 2008, 2011）开创了一种新颖的方法，用于对大规模调查数据集进行视觉分类。本网页允许任何人下载该项目中星系的GZ分类结果。
