CORESHINE and the dark core of stars, about GHOST CLOUDS in the stars? wow......

"Ghost Clouds of the Milky Way Incubating Stars"
It's an article about how much larger (and potentially faster) the particles surrounding new dark cores of stars are, and the phenomenon they call starshine which happens when this cosmic dust surrounds the dark core. They thought the light would shine right through very small particles, but the particles must be larger than they thought.

QUOTE:
"'Dark clouds in our Milky Way galaxy, far from Earth, are huge places where new stars are born. But they are shy and hide themselves in a shroud of dust so that we cannot see what happens inside,' said Laurent Pagani of the Observatoire de Paris and the Centre National de la Recherche Scientifique, both in France. 'We have found a new way to peer into them. They are like ghosts because we see them but we also see through them.'"
"Pagani and his team first observed one case of the coreshine phenomenon in 2009. They were surprised to see that starlight was scattering off a dark core in the form of infrared light that Spitzer could see. They had thought the grains of dust making up the core were too small to deflect the starlight; instead, they expected the sunlight would travel straight through. Their finding told them that the dust grains were bigger than previously thought -- about 1 micron instead of 0.1 micron (a typical human hair is about 100 microns)."
