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. The
above false color image
was post-processed by
Forrest Hamilton
