银河系不是由一个蒸发的湖泊形成的。这个色彩斑斓的水池，宽约10米，被称为“锡勒斯泉”，位于美国怀俄明州的黄石国家公园。在人工照明下，这些颜色是由生长在温泉中的细菌层造成的。蒸汽从泉水中升起，被与黄石热点有关的地下岩浆加热。我们银河系的中心带在头顶上呈拱形，这条带被数十亿颗恒星照亮。这张照片是2014年拍摄的16张全景图。如果黄石热点像64万年前那样引发另一次超级火山爆发，北美的大部分地区将受到影响。

The Milky Way was not created by an evaporating lake. The colorful pool of water, about 10 meters across, is known as Silex Spring and is located in Yellowstone National Park in Wyoming, USA. Illuminated artificially, the colors are caused by layers of bacteria that grow in the hot spring. Steam rises off the spring, heated by underground magma associated with the Yellowstone Hotspot. Unrelated and far in the distance, the central band of our Milky Way Galaxy arches high overhead, a band lit by billions of stars. The picture features a 16-image panorama taken in 2014. If the Yellowstone Hotspot causes another supervolcanic eruption as it did about 640,000 years ago, a large part of North America would be affected.
