SNOWBALL?, page 1

"A controversial theory that the Earth is being bombarded constantly by comet-like objects the size of small houses and consisting mostly of water has received support from recent satellite observations.

Observations indicate that these objects are vaporizing and leaving behind clouds in the atmosphere that are 10-100 kilometers across and have high concentrations of water vapor. This interpretation was first suggested in the mid-1980s from the UV satellite observation of dark spots in the "dayglow" (ultraviolet light produced by sunlight interacting with oxygen in the atmosphere). Large clouds of water vapor would absorb the UV light at the frequencies that the satellite was observing, thus leaving a dark spot or "hole" in the dayglow.
