  Spiral galaxy is a stellar system where there are outwards arched spiral arms from roundish (spiral galaxies) or bar-shaped (barred spiral galaxies) central condensation.
  
  The apparent shape of spiral galaxied depends on out observation direction. From above they are quite round. From the side they lens-shaped with a bulge in the middle.
  
  Generally a rather large instrument, good weather conditions and observational expereince are needed to see spiral arms. Usually spiral galaxies look like a fuzzy spots.
