Comment |
The nebula is shown
rotated 90 degrees clockwise.
Although commonly
called The Heart Nebula, IC 1805 is actually classified as an open
cluster. This nebulous region is located in the eastern part of
Cassiopeia, about 7,500 light-years away. The area is dominated by
the red glow of energized hydrogen. At the center of the "heart" is
an open cluster known as Melotte 15.
