The
Witch's
Broom
Ten
thousand
years ago,
before the
dawn of
recorded
human
history, a
new light
must
suddenly
have
appeared
in the
night sky
and faded
after a
few weeks.
Today we
know this
light was
an
exploding
star and
record the
colorful
expanding
cloud as
the Veil
Nebula.
Pictured
above is
the west
end of the
Veil
Nebula
known
technically
as NGC
6960, but
less
formally
as the
Witch's
Broom
Nebula.
The
rampaging
gas gains
its colors
by
impacting
and
exciting
existing
nearby
gas. |
