这个派对仍在螺旋星系ngc3310中进行。大约1亿年前，NGC 3310可能与一个较小的星系相撞，导致这个大型螺旋星系在恒星形成的巨大爆发中被照亮。碰撞过程中重力的变化产生了密度波，压缩了现有的气体云，触发了恒星形成过程。这张来自双子座北望远镜的特色图片非常详细地展示了这个星系，颜色编码，粉红色突出气体，白色和蓝色突出恒星。星系中的一些星团相当年轻，这表明星暴星系可能会在相当长的一段时间内保持星暴模式。NGC 3310横跨约5万光年，距离我们约5000万光年，用小型望远镜朝向大熊星座就能看到它。

The party is still going on in spiral galaxy NGC 3310. Roughly 100 million years ago, NGC 3310 likely collided with a smaller galaxy causing the large spiral galaxy to light up with a tremendous burst of star formation. The changing gravity during the collision created density waves that compressed existing clouds of gas and triggered the star-forming party. The featured image from the Gemini North Telescope shows the galaxy in great detail, color-coded so that pink highlights gas while white and blue highlight stars. Some of the star clusters in the galaxy are quite young, indicating that starburst galaxies may remain in star-burst mode for quite some time. NGC 3310 spans about 50,000 light years, lies about 50 million light years away, and is visible with a small telescope towards the constellation of Great Bear Ursa Major.
