NGC 2440——一颗新白矮星的茧。
NGC 2440: Cocoon of a New White DwarfCredit: H. Bond (STScI), R. Ciardullo (PSU), WFPC2, HST, NASA
Explanation: Like a butterfly, a white dwarf star begins its life by casting off a cocoon that enclosed its former self. In this analogy, however, the Sun would be a caterpillar and the ejected shell of gas would become the prettiest of all! The above cocoon, the planetary nebula designated NGC 2440, contains one of the hottest white dwarf stars known. The white dwarf can be seen as the bright dot near the photo's center. Our Sun will eventually become a "white dwarf butterfly", but not for another 5 billion years. The above false color image was post-processed by Forrest Hamilton. 这张更夸张些 像一张张开的大口!看!还有虎牙呢! :shock: 8) 意味着消亡。。。。。。
