NGC 2440: Cocoon of a New White Dwarf

NGC 2440: Cocoon of a New White Dwarf
Title
|
|
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! In the above cocoon [ http://hubblesite.o…], the planetary nebula designated NGC 2440, contains one of the hottest white dwarf stars known. The white dwarf [ http://imagine.gsfc…] 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 [ http://heritage.sts…] was post-processed by Forrest Hamilton [ http://heritage.sts…].
