A 4.5 billion-year-old asteroid just turned up carrying the complete genetic alphabet.

Scientists found all 5 building blocks of DNA and RNA in samples from asteroid Ryugu: adenine, guanine, cytosine, thymine and uracil. Every one that life relies on.

Japan’s Hayabusa2 spacecraft scooped that material off Ryugu’s surface and carried it back to Earth.

Here’s why that matters. These are the molecules that store and copy genetic information, and they were sitting in space rock long before anything on our planet was alive.

So maybe Earth didn’t have to invent life’s ingredients from scratch.

Maybe they got delivered.
