What diagram illustrates the Hubble Sequence for classifying galaxies?
Answer
The tuning fork diagram
The Hubble Sequence, originally developed in the 1920s to categorize galaxies by their morphology, is most commonly visualized as a tuning fork diagram. This model demonstrates a continuum of galaxy shapes, organizing them based on their visual appearance rather than their age or mass, allowing astronomers to group them into broad structural categories.
