New evidence life on Earth began in space
"SCIENTISTS examining the first dust samples collected from a comet have found complex carbon molecules, supporting the theory that ingredients for life on Earth originated in space.
The organic material was found in early studies of samples from the comet Wild 2, brought back to Earth by the Stardust space probe seven weeks ago.
Stardust collected hundreds of grains of dust as it flew through the tail of the comet two years ago.
Analysis suggests a high concentration of complex molecules of the kind thought necessary for the evolution of life."
