The formation and evolution of planets is the driving force behind both where and how we might find life beyond Earth. This complex and lengthy process first begins with a massive ball of gas and dust that swirls until it flattens into a disk, followed by rocks ranging in size from pebbles to kilometer-scale objects clumping together in a process known as accretion, as they too swirl around within the larger disk and form rocky planets closer to the star and the farther out planets collect the gas, ice, and dust that the star couldn’t evaporate. Until now, researchers have been limited to visualizing the swirling gas and dust forming planets through computer models.
