Origin of Life on Earth
The scientific community is divided on the origins of life on Earth, with two main theories: life stemmed from the planet's primordial soup or arrived on interstellar debris.
However, a study published in the Monthly Notices of the Royal Astronomical Society suggests that life's ingredients may have come from microscopic particles of cosmic dust filled with amino acids.
Amino acids are the building blocks of life, with over 500 naturally occurring compounds.
Life may have arrived on Earth aboard microscopic particles of cosmic dust.
This theory challenges the idea that life arrived on big space rocks, such as asteroids, and instead proposes that cosmic dust played a key role in delivering life's ingredients to our planet.
