Hundreds of new stars are igniting in the wake of intense gravitational interactions between four galaxies, new observations reveal.

The four galaxies – called Robert's Quartet – lie about 160 million light years from Earth in the southern constellation Phoenix. They are crowded into a space just 150,000 light years across – only 1.5 times the width of our galaxy, the Milky Way.

Babies are just so sweet.
