Origins of Life on Earth
The scientific community is divided on the origins of life on Earth, with two main camps: life stemming from the planet's primordial soup of amino acids and organic molecules, and life arriving on interstellar debris.
However, a new 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 life's most elemental building blocks.

- Amino acids may not have arrived on big space rocks.
- There are over 500 naturally occurring compounds known as amino acids.
