What specific classification is the Milky Way galaxy given in the Hubble scheme?
Answer
SBbc barred spiral galaxy
The Milky Way is classified specifically as a spiral galaxy, but further refinement places it within the barred spiral category. The designation SBbc indicates that it possesses a central bar structure composed of stars crossing the nucleus, from which the spiral arms emerge. The 'bc' part of the code further specifies that the spiral arms are moderately wound. This classification contrasts with 'S' types, which lack the central bar feature, confirming its status as a barred spiral, a significant subdivision within the broader spiral class.
