Latest Comet dust Stories
Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System.
Rsearch provides the first constraint on the age of cometary material from a known comet.
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution.
Scientists are tracking the violent convulsions in the giant cloud of gas and dust that gave birth to the solar system four and a half billion years ago via a few tiny particles from comet Wild 2.
Comet Tempel-1 may have been born in the region of the solar system occupied by Uranus and Neptune today, according to one possibility from an analysis of the comet's debris blasted into space by NASA's Deep Impact mission.
NASA and University of Arizona researchers have discovered pristine mineral grains that formed in an ancient supernova explosion. The grains were among other extraterrestrial dust plucked by high-flying NASA research aircraft from Earth's upper atmosphere after they were delivered to Earth by a comet or primitive asteroid.
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...
