Re: [asa] Protoplanet "without form and void"

Update (Augmentation).

The latest issue of Scientific American (May) features planetary formation. The first page of the article has a wonderful illustration depicting the vast stellar accretion disk with a protoplanet in the foreground. Earlier in time, this planet could be illustrated as being without form within the void that is illustrated.

Since stellar nurseries seem to be the norm, the illustrated disk might appear surprisingly blue -- like our sky, and for the same reason -- to any observer due to the brightness and proximity of the nursery neighbors.

What if Gen. is an eye-witness account? A lot can happen in 40 days when one is on top a mountain in the hands of God. Especially a Genesis author.

Care to see some short bullets on my literal view which takes 21 century science, primarily astronomy and cosmology, and adds it to the context?

  Well, that's my own spin on, of course.

  A little over a month ago, an image was produced that revealed a void in a young stellar accretion disk. In the center of this void is, likely, a protoplanetary disk which will eventually produce a planet (or a brown dwarf). [Protoplanetary disks are very large compared to a planet, so it is assumed that is what they are able to see, since planets are too small to see.]

  This planet is without form, and it is in a void, which has been a prediction of planetary formation theories. However, this is the very first image of one.

  http://www.amnh.org/science/papers/planetformation_080326.php

  [Oddly, they seem to go out of their way to describe the void, using: "depleted region of dust", "hole", and "darker area". ]

  Of course, the red and yellow coloring is false color imaging to enhance certain properties of the disk, probably temperature.

  The particle sizes of young disks are very effective scatterers of light. More specifically, they will cause Rayleigh Scattering which produces one dominant color from any bright starlight - blue. Many stellar nurseries have been observed, and they can be very close to one another initially, as well as, very bright. Thus, some early disks will, likely, appear blue even to the naked eye. An ancient observer might best describe this emense span of blue as "waters".

  I find this very interesting.
