This cosmic baby photo collection contains 31 young star systems, images captured by the Atacama Large Millimeter Array in Chile. In the bottom right corner, you’ll find a simulation of our own solar system at just 1 million years old. The infant stars at the center of these systems formed from large clumps of super chilly dust and gas that buckled under their own gravity. Over many millennia, this material spins into disks with dense, sizzling centers that morph into stars.
The surrounding disks are known as protoplanetary disks, and scientists think that the leftover gas and dust within the
