A) Elliptical galaxies are mostly found at the center of galaxy clusters.

B) The dwarf elliptical galaxies are probably the most common type of galaxy in the universe.

C) Spiral galaxies contain abundant clouds of dust and gas.

D) Elliptical galaxies vary greatly in both size and mass with diameters ranging from 3000 lightyears to more than 700,000 lightyears, and masses from 10⁵ to nearly 10¹³ solar masses.

E) Elliptical galaxies do not contain abundant gas and dust. So the star formation probability is extremely small in elliptical galaxies.

F) Spiral galaxies have a huge amount of hot massive stars in their spiral arms.

G) Elliptical galaxies are redder in color. Spiral galaxies are red in color in the center and blue color in arms and bars.
