An article published in the journal “Astronomy & Astrophysics” describes the study of the protoplanetary disk AS 209. A team of researchers led by Davide Fedele of INAF Arcetri, Italy, used the ALMA radio telescope to observe that disk of gas and dust around a star in its formation phase showing a central core and two large rings with two large gaps. Their conclusion is that there’s at least one planet with a mass that could be close to Saturn’s orbiting at a considerable distance from its star.
