The evolving wreckage, known famously as the Antennae, is the result of spiral galaxy NGC 4038 colliding with NGC 4039. As gravity restructures each galaxy, clouds of gas slam into each other, bright blue knots of stars form, massive stars form and explode, and brown filaments of dust are strewn about.
