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 above
zoomable view 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 above
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 focussed
on how massive stars form and how they affect their environment
