NGC 2440: Cocoon of a New White Dwarf


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, 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.
