Cosmic Dust Clouds Point to Non-Carbon Life Forms

Intriguing evidence of life-like corkscrew structures that form from inorganic substances in space hint at the possibility that life beyond earth may not necessarily use carbon-based molecules as its building blocks. They may also point to a possible new explanation for the origin of life on earth.

In 2007, an international team discovered that under the right conditions, particles of inorganic dust can form helical structures that can interact with each other in ways that are usually associated with organic compounds and life itself.
