一组Comet 17P/Holmes照片
Comet 17P/Holmes shocked astronomers on Oct. 24, 2007, with a spectacular eruption. In less than 24 hours, the 17th magnitude comet brightened by a factor of nearly a million, becoming a naked-eye object in the evening sky. Look for a golden 2.5th magnitude fuzzball in the constellation Perseus after sunset.[ 本帖最后由 sky0907 于 2007-10-30 20:22 编辑 ] 跟月亮有一拼::070821_09.jpg::
