In a possible first, a giant, faraway planet may have been caught in the act of growing moons.

Seen in an image from the ALMA Observatory in Chile, the young planet orbits a small star roughly 370 light-years away, and it appears to be swaddled in a dusty, gassy disk—the exact type of structure scientists think produced Jupiter’s many moons billions of years ago.

“It’s quite possible there might be planet-size moons in formation around it,” study leader Andrea Isella of Rice University says in a statement.

“It’s certainly plausible that giant planets could have giant moon-forming disks around them,” says Stanford University’s Bruce Macintosh of
