Hubble 5 is a striking example of a "butterfly"
or bipolar (two-lobed) nebula. The heat generated by fast
winds causes each of the lobes to expand, much like a pair
of balloons with internal heaters. This observation was taken
Sept. 9, 1997 by the Hubble telescope's Wide Field and
Planetary Camera 2. Hubble 5 is 2,200 light-years away in
the constellation Sagittarius.
