Particles from any icy comet that were collected and returned to Earth aboard a NASA science satellite show dozens of minerals that form only in extreme heat -- a finding that complicates theories about how the solar system formed, scientists said on Monday.

Scientists said Monday they have begun slicing and dicing the first of hundreds of microscopic specks of comet dust, virtually unchanged since the birth of the solar system, that a NASA spacecraft successfully returned to Earth in late January.

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
