WeBo 1 is a very unusual young planetary nebula between the Heart (IC 1805) and Soul (W5) nebulas in Cassiopeia. Two things make it unusual. First is its shape. Rather than being globular or spherical in shape, it presents as a thin ellipse. This is likely due to the fact that its progenitor star (not visible in the frame) is part of a binary system, and the gravitational interaction with its companion star caused material to be ejected from the system in a disk shape. Second, the binary companion (visible at the center of the nebula) is what scientists call a barium star. Barium stars are fairly rare.
