Description: NGC 7640 is a barred spiral galaxy in the constellation of Andromeda. Galaxies of this type are recognizable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s center.
NGC 7640 might not look much like a spiral, but this is due to the orientation of the galaxy with respect to an observer on Earth.
There is evidence that NGC 7640 has experienced some kind of interaction in its past. Galaxies contain vast amounts of mass, and therefore affect one another via gravity.
Sometimes these interactions can be mild, and sometimes hugely dramatic, with two or more colliding and merging into a new, bigger galaxy.
It is not immediately obvious this is a spiral galaxy because it is edge on.
