The Atacama Large Millimeter/submillimeter Array in Chile glimpsed a dusty disk of potentially moon-forming material around a baby exoplanet about 370 light-years from Earth. The Jupiter-like world is surrounded by enough material to make up to 2.5 Earth moons, researchers report online July 22 in the Astrophysical Journal Letters. Observations of this system could offer new insight into how planets and moons are born around young stars.
