In a classic \"Charlie Brown\" Halloween tale, one character believes in the pumpkin equivalent of an Easter Bunny or Tooth Fairy, but NGC 2292 and NGC 2293 are real. At 109,000 light-years across, the diameter of our Milky Way, they don't just form a Great Pumpkin, they form the greatest pumpkin of all.What looks like two glowing eyes and a crooked carved smile is a snapshot of the early stages of a collision between the two galaxies. This interacting pair seems to be the construction of a giant spiral galaxy. It may depend on the specific trajectory the colliding galaxy pair is following.The ghostly arm making the \"smile\" may be just the beginning of the process of rebuilding a spiral galaxy, say researchers. Therefore, it's a difficult area to pinpoint far-flung distant background galaxies from the plethora of stars seen in the field.
