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!
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.
