This Hubble Space Telescope image features two merging galaxies in the VV-689 system, nicknamed the Angel Wing. Unlike chance alignments of galaxies, which only appear to overlap when viewed from our vantage point on Earth, the two galaxies in VV-689 are in the midst of a collision. The galactic interaction has left the VV-689 system almost completely symmetrical, giving the impression of a vast set of galactic wings.

“Zoo Gems,” interesting galaxies from the Galaxy Zoo citizen science project is a crowdsourced program and relies on hundreds of thousands of volunteers to classify galaxies and help astronomers wade through a deluge of data from robotic telescopes. In the process, volunteers discovered a gallery of weird and wonderful galaxy types, some not previously studied. A similar, project called Radio Galaxy Zoo: LOFAR is using the same crowdsourcing approach to locate supermassive black holes in distant galaxies.

“动物园宝石(Zoo Gems)”,来自银河动物园公民科学项目的有趣星系是一个众包项目,依靠数十万志愿者对星系进行分类,并帮助天文学家通过机器人望远镜获取大量数据。在这个过程中,志愿者们发现了一系列奇怪而奇妙的星系类型,其中一些以前从未被研究过。一个类似的名为“射电星系动物园(Radio Galaxy Zoo)”的项目:LOFAR正在使用同样的众包方法来定位遥远星系中的超大质量黑洞。
