Comet have a compound important for life as stated by NASA

The Stardust space probe of NASA extracted particles extracted from the tail of comet Wild 2, which contains amino acid glycine, a key protein. In this way, it reinforces the theory that the components of life came to Earth from outer space.

NASA scientists extracted gas and dust samples collected in a small fountain lined with a spongy material called ultra airgel. These were obtained from the depths of the solar system, about 390 million kilometers from Earth in January 2004. And 2 years later, were brought back to our planet in a container off the ship and landed by parachute in the Utah desert.

The comet Wild 2 is known astronomer Paul Wild (whose pronunciation is "Vilda"), and it is believed this feature of comets, is very well preserved material dating from the beginning of the solar system and which may contain clues on the formation of the Sun and planets.

The astrobiĆ³loga Jamie Elsila the Goddard Flight Space Center in Greenbelt, Maryland, the principal author of the recent research indicated that glycine, one of 20 amino acids in proteins of the Earth took time for confirmation and filed in Published in the journal Meteoritics and Planetary Science at a meeting of the American Chemical Society in Washington, DC.

It should be noted that scientists have tried for a long time to decipher whether these complex organic compounds originated on Earth or in space. And discoveries like this gives credence to the notion that extraterrestrial objects like meteorites and comets might have planted the seeds of life.
