Hubble watches how a giant planet grows
Ever made a complete mess in your kitchen while baking? At moments it may look like flour is floating in the air, but once you’ve added plenty of water and formed your dough, the bread becomes more like a ball. A similar process is at work in a far-flung solar system known as PDS 70, except the flour and water are swapped for gas and dust. In the case of planet PDS 70b, gas and dust are slowly being drawn in as this distant world builds mass over millions of years.
