Explanation:
Is the heart and soul of our Galaxy located in
Cassiopeia
? Possibly not, but that is where two bright
emission nebulas
nicknamed
Heart and Soul
can be found. The
Heart Nebula
, officially dubbed
IC 1805
and
visible in the featured
image on the right, has a shape reminiscent of a classical
heart symbol
. Both nebulas shine brightly in the red light of
energized
hydrogen
. Several young
open clusters
of
stars
populate the image and are
visible here
in blue, including the nebula centers.
Light
takes about 6,000 years to reach us from these nebulas, which together span roughly 300
light years
.
Studies
of stars and clusters like those found in the
Heart
and
Soul
Nebulas have focused on how
massive stars
form and how they
affect their environment
.
