Planet Formation in Earth-like Orbit around a Young Star

ALMA's Best Image Yet of a Protoplanetary Disk

The disks of dust and gas that surround young stars are the formation sites of planets. New images from the Atacama Large Millimeter/submillimeter Array (ALMA) reveal never-before-seen details in the planet-forming disk around a nearby Sun-like star, including a tantalizing gap at the same distance from the star as the Earth is from the Sun.

This structure may mean that an infant version of our home planet, or possibly a more massive "super-Earth," is beginning to form there.
