(b) Tiny phytoplankton swim among crystals of ice in the Antarctic Sea. They range from a fewmicrometers (1μm is 10m) to as much as 2 mm (1 mm is 10m) in length. (c) These two colliding galaxies, known as NGC4676A (right) and NGC 4676B (left), are nicknamed “The Mice” because of the tail of gas emanating from each one. They arelocated 300 million light-years from Earth in the constellation Coma Berenices. Eventually, these two galaxies will merge intoone.
