42 tuning fork diagram
November 7, 2015 - Although this scheme, also known as the Hubble Tuning Fork diagram, is now considered somewhat too simple, the basic ideas still hold. The diagram is roughly divided into two parts: elliptical galaxies (ellipticals) and spiral galaxies (spirals). “S0,” or lenticular galaxies such as Mrk ... Elliptical galaxies make up the ... of the fork. The most round ellipticals are on the left and they get flatter towards the right. From left to right, the spirals and barred spirals become less tightly wound with smaller middles. All of the galaxies also have more dust and gas in them as you go from left to right in the diagram... In 1926, astronomer Edwin Hubble realised that there are several types of galaxy and developed a classification scheme, known as the Hubble tuning fork diagram. The diagram is roughly divided into two parts: elliptical galaxies (ellipticals) and spiral galaxies (spirals). Tuning fork diagram
