The new observations, published Thursday in The Astrophysical Journal Letters, may shed light on how moons and planets form in young stellar systems.
The detected region is known as a circumplanetary disk, a ring-shaped area surrounding a planet where moons and other satellites may form. The observed disk surrounds exoplanet PDS 70c, one of two giant, Jupiter-like planets orbiting a star nearly 400 light-years away...
