Braided and serpentine filaments of glowing gas suggest this nebula's popular name, The Medusa Nebula. Also known as Abell 21, this Medusa is an old planetary nebula some 1,500 light-years away in the constellation Gemini. Like its mythological namesake, the nebula is associated with a dramatic transformation. The planetary nebula phase represents a final stage in the evolution of low mass stars like the sun as they transform themselves from red giants to hot white dwarf stars and in the process shrug off their outer layers. Ultraviolet radiation from the hot star powers the nebular glow. The Medusa's transforming star is the faint one near the center of the overall bright crescent shape. In this deep telescopic view, fainter filaments clearly extend below and right of the bright crescent region. The Medusa Nebula is estimated to be over 4 light-years across.

捕捉生命的瞬间,极尽挽留,终究还是脱兔般溜走,在我思忆的影像中翻来覆去。风华是一指流砂,苍老了一段年华,那么,我的年华呢,你的年华呢,转眼间一切沉淀于梦里,忧伤千缕。
Capture the moment of life, try to retain, after all, or rabbit slip away, in my memory of the image over and over. Elegance is a flow of sand, old time, so, my time, your time, in the blink of an eye all precipitated in the dream, sad thousand wisps.
