Curiosity rover finds life building blocks

Planetary scientists are analyzing never-before-seen organic compounds found in a Martian crater by the Curiosity rover.

These molecules are widely considered the building blocks for the origin of life on Earth, though experts are still determining how they formed on Mars.

The findings suggest that the Red Planet's ancient environment was far more complex than previously thought.

This discovery marks a major breakthrough in the ongoing search for evidence of past or present alien life.
