nebulosity

Prof. Barnard adds that the nebulosity is easily visible in a 12-inch telescope.

It is the nebulosity out of which the whole came and into which all is ultimately occluded.

There are bristled comets; these resemble the skins of beasts with the fur on them, and are surrounded by a nebulosity.

Repeating the photographs at intervals, it was found that this nebulosity was rapidly changing in shape.
