Graphical Abstract — Geoscience How and where did life on Earth originate? To date, various environments have been proposed as plausible sites for the origin of life. However, discussions have

An artistic reconstruction of Earth during the Hadean eon (~4.5 billion years ago). Intense volcanic activity, heat from accretion, and frequent impacts kept the young Earth in a molten state.

The conceptual space of origin-of-life questions. Each axis corresponds to one of the three constraints identified above: historical adequacy, natural spontaneity, and similarity to life-as-we-know-it. Combinations of low and high

By efficient use of local extraterrestrial resources and promotion of a more sustainable supply chain, synthetic biology can contribute significantly to human space exploration missions. This is done through incorporating

Best fit results from a joint transit and RV fit using a quasi-periodic GP model to account for the excess RV scatter in the RVs. a) Top: NEID (yellow) and
