    Life's building blocks can form in the harsh environment of deep space, a new study suggests, bolstering the odds that a comet or meteorite strike may have jump-started biological evolution on Earth. Comets and the Origin of Life | The idea that comets may be connected with the origin of life on Earth was considered heresy a few decades ago, with scientists shying away from this possibility as if from a medieval superstition. However the case that comets may have contributed at least the complex organic building blocks of life has become very strong, and mechanisms have now been identified.

    Orbits and Origins of Comets. Comet Orbits Most comets travel in highly elliptical orbits around the Sun with orbital periods (time between returns) ranging from just over three years to millions of years. Some comets, called "periodic comets", return near the Sun every few years, and travel no further from the Sun than the orbit of Jupiter. The origin-of-life (OOL) problem ha s be en traditionally viewed as a informational barrier, whereas comets, when t hey have been considered at all, have been treated as passive, information.
