🪐 Hidden over 430 light-years away in the constellation Ophiuchus, the protoplanetary disk around the young star AS 209 is riddled with striking gaps and rings thought to be carved by newly forming planets. ALMA observations revealed the disk’s outermost gap may be created by a planet similar in mass to Neptune, astonishing astronomers because it would be forming over 200 astronomical units from its star—far beyond the realms where planets are usually born. ✨
