Icy cobwebs of hydrogen cyanide may have sparked life on Earth

Scientists have found that a poisonous chemical called hydrogen cyanide can turn into special icy crystals when it's very cold.

These crystals look like tiny cobwebs and can start important chemical reactions.

These reactions might have helped create the building blocks of life, like DNA, on Earth.

The scientists think this could have happened in very cold places, like on comets or icy moons.

This is different from the old idea that life started in warm, watery places.

The study also helps explain why a moon called Titan has a lot of these special chemicals.

So, these icy crystals might have been the spark that started life on Earth and maybe even on other icy worlds.
