Since the 1990s, scientists have detected thousands of exoplanets orbiting distant stars, but the discovery of baby protoplanets embedded within stellar expanses of gas and dust has proven to be a challenge. An international team of astronomers has used a new technique to finally discover not one, but three infant planets around a newborn star - an incredible finding that's affirming long-held assumptions about planet formation.

A stunning photograph taken from the ALMA observatory in Chile shows a young star surrounded by a large disk of gas and dust. Like our very own Milky Way, this protoplanetary disk exhibits a spiral structure -- a feature that could solve a lingering mystery about how planets start to form.
