A six-year-old sample from asteroid Ryugu just confirmed all five major DNA building blocks, and Dr. Samantha Yammine breaks down why that finding matters more than the headlines suggest. It separates what the data actually shows from the more dramatic claim that life itself started elsewhere.

The conversation traces the Hayabusa2 mission's pristine sample collection, built specifically to rule out the Earth contamination that clouded earlier meteorite research. It explains a new detail from this study: the ratio of nucleobases shifts with ammonia levels, offering a clue to what other life forms might carry.

It ends with the sheer improbability of any of this coming together at all, and a free, limited-time chance to send a name into deep space aboard the Nancy Grace Roman Telescope before the window closes.
