Trio of Infant Planets Discovered around Newborn Star

Artist impression of protoplanets forming around a young star.

Two independent teams of astronomers have uncovered convincing evidence that three young planets are in orbit around an infant star known as HD 163296. Using a new planet-finding strategy, the astronomers identified three discrete disturbances in a young star’s gas-filled disk: the strongest evidence yet that newly formed planets are in orbit there. These newly formed planets are depicted here in an artist impression.
