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 upper right, has a shape reminiscent of a classical
heart symbol. The shape is perhaps fitting for
Valentine's Day. The
Soul Nebula is officially designated IC 1871 and is visible on the lower left.
Both nebulas shine brightly in the red light of
energized hydrogen, one of three colors shown in
this three-color montage.
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.
