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

The peak temperature achieved by all tracer particles in simulations of a 1 km diameter comet impacting at 10 km s−1 (left) and 40 km s−1 (right) in a provenance

Normalized nosZ transcript abundance in metatranscriptomes of marine (red) and lacustrine (green) euxinia. Shown is the ratio of nosZ to rplF transcripts for comparison across 245 datasets with different sequencing

Impacts of microgravity on plants (A) At the phenotypic level, plants exhibit random root growth direction, larger branch and silique angles, delayed flowering, and smaller seed size. (B) At the
