A still-forming planet has been detected early in its birth process, thanks to what may have been a chance encounter with a passing star that flipped part of the obscuring disk out of the way, exposing the baby planet.
Astronomers have discovered 4 very large gas planets orbiting a young star only 2 million years old. Looks like we need a new model of planetary formation.
Two independent teams of astronomers have used ALMA to uncover convincing evidence that three young planets are in orbit around the infant star HD 163296.
