This image from data taken by ESO’s Atacama Large Millimeter/submillimeter Array (ALMA) shows the planet-forming disc around the young, Sun-like star TW Hydrae. The inset image zooms in on the gap nearest the star, which is at roughly the same distance as the Earth is from the Sun. The additional concentric light and dark features represent other planet-forming regions farther out in the disc.
