«This observation gives us a good picture of part of the composition of ISON and, by extension, of the proto - planetary disk from which the planets were formed,» said Carey Lisse, leader of NASA's Comet ISON Observation Campaign and a senior research scientist at the Johns Hopkins University Applied Physics Laboratory.

So called because the smaller varieties almost resemble planetary disks when viewed through a telescope, planetary nebulae represent a stage at the end of the stellar life cycle rather than one at the beginning.

Just recently, a collaboration of astronomers from ETH Zurich and Max Planck Institute for Astronomy used SPHERE to capture images of planetary disks that are present around newborn stars.

While planets typically migrate inward due to the torque (or gravitational push) of the pancake - like proto - planetary disks of dust and gas in which they form (seen in this picture), what hasn't been clear until now is what causes them to stop.

The amount of these three elements available to make planets and where those elements can be found in a proto - planetary disk, should determine where exactly rocky planets can form and what their internal structures will be.

The reason for these near - resonance configurations is not yet clear: tidal evolution could have played a role in extracting planets from resonance, and so might turbulence in the original proto - planetary disk.
