Proto-planetary disks in Orion
A Hubble Space Telescope image shows "proplyds," or protoplanetary disks, in the Orion Nebula.
According to NASA, nebulae, flattened disks of gas and dust, "are the likely birthplaces of new planetary systems. Hubble provided visual proof that pancake-shaped dust disks around young stars are common, suggesting that the building blocks for planet formation are in place."
