(DESCRIPTION)
A white, blue, and orange spiral galaxy.
A white, blue, and orange spiral galaxy.
Text, A galaxy, containing billions of stars, floats serenely in space.
A wider view shows that it is not alone.
A second, smaller spiral galaxy is beside the first.
Two orange spiral galaxies neighbor a white spiral galaxy.
Text, Gravity pulls galaxies toward each other and binds them into groups.
Collisions are inevitable.
Here, two galaxies are engaged in a collision.
A wisp of gas binds two galaxies together.
Text, Eventually they'll merge to form one, much larger galaxy.
