【生生不息】
天空中的螺旋星系
像被微風吹過的蒲公英
將它的種子散佈到太空
微風中的螺旋星系
在每小時700萬公里的行進中
衝破銀河系的氣體
留下的物質流
鼓動新的恆星生成
This spiral galaxy not only looks like a dandelion caught in a breeze, it's spreading its "seeds" into space like one too. Traveling at roughly 7 million km/hour, much of the galaxy's gas is being torn away, encouraging new star formation in the stream of material left behind. pic.twitter.com/QNIlp3Re0b

That’s no onion ring! That's Hoag's Object, about 600 million light-years away. This ring-type galaxy is slightly larger than our Milky Way with a blue ring containing clusters of young, massive stars. The yellow center contains mostly older stars. #NationalOnionRingDay pic.twitter.com/Dr0rZ2yy37
