feel that the outflows from these lobes resemble
the exhausts of two jet engines facing each
other nose to nose.
In the adjacent picture, planetary
nebula M2-9 is shown on the left. At right
is a daytime picture of a Delta rocket launched
from Cape Canaveral in Florida with the Stardust
Mission to Comet Wilde in February 1999. The
similarities between one lobe of the nebula
and the rocket plume (shown in firey yellow)
are stunningly obvious.
