M16: Pillars of Creation
Explanation: It has become one of the most famous images of modern times.
This image
, taken with the
Hubble Space Telescope
in 1995, shows
evaporating gaseous globules
(EGGs) emerging from pillars of molecular
hydrogen gas
and
dust
. The
giant pillars
are
light years
in length and are so dense that interior gas
contracts gravitationally
to form stars. At each
pillars' end
, the intense radiation of bright young stars causes low density material to boil away, leaving
stellar nurseries
of dense
EGGs
exposed. The
Eagle Nebula
, associated with the
open star cluster
M16
, lies about 7000
light years
away. The
pillars of creation
were again
imaged
by the orbiting
Chandra X-ray Observatory
, and it was found that most
EGGS
are not strong emitters of
X-rays
.
