Explanation:
The Butterfly Nebula
is only thousands of years old.
As a central star of a
binary system aged,
it threw off its outer envelopes of gas in a strong stellar wind. The remaining stellar core
is so hot it ionizes the previously ejected gas,
causing it to glow.
The different colors of this
planetary nebula are determined by small
differences in its composition.
This
bipolar nebula
will continue to shine brightly for only a
few thousand more years, after which its central star
will fade and become a
white dwarf star. The above picture is one of the
first ever taken by the Very Large Telescope (VLT),
a new 8.2-meter telescope located in
Chile.
