a nebula so thick with gravity and gas it starts producing stars, no parenting license required.
means a dense cloud of gas and dust in space collapsing under its own gravity to form new stars.
from astronomers borrowed the domestic metaphor because these clouds cradle protostars through infancy, the same way a nursery shelters newborns before they're ready for the world.
