The Heart and Soul Nebulas
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 bottom right, has a shape reminiscent of a classical
heart symbol. The
Soul Nebula is officially designated IC 1871 and is visible on the upper left.
Both nebulas shine brightly in the red light of
energized hydrogen. Also shown in this three-color montage is light emitted from
sulfur, shown in yellow, and
oxygen, shown in blue. Several young
open clusters of
stars are visible near 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.
