Answer to Question 144

A144:A lenticular galaxy is a lens-shaped galaxy. These enormous groupings of older stars have a smooth, even distribution and very little internal structure. 
Some lenticular galaxies (abbreviated SO galaxies) include M84 (in Virgo), M85 (in Virgo), M86 (in Virgo), NGC 5866 (the Spindle Galaxy), and perhaps M102.
