The galaxies show every possible shape and size, astronomer Phil Plait wrote on Slate. Many are distorted, victims of collisions with other galaxies, their mutual gravity pulling them into weird shapes like taffy quadrillions of kilometers across. Many are very blue, showing active star formation, while others are exceedingly red, probably galaxies much farther away, their light taking far longer to reach us. Note that most of the very red galaxies are smaller dots, another indication of their tremendous distance.
