"So far, planet formation has mostly been a topic tackled by computer simulations," astronomer Sascha Quanz of ETH Zurich in Switzerland, leader of the research team, said in a statement. "If our discovery is indeed a forming planet, then for the first time scientists will be able to study the planet formation process and the interaction of a forming planet and its natal environment empirically at a very early stage."

The possible planet seems to fit the picture scientists are building of how worlds form. Stars themselves are born in clouds of gas and dust, and after the form, a disk of leftover material often orbits them. From this disk, baby planets can take shape. That's what appears to be happening here.
