The Lucy spacecraft's 2025 flyby of a main-belt asteroid has produced a detailed portrait of a doubly-tumbling, bilobate rock with iron-rich clays - evidence of liquid water from 155 million years ago.
New impact simulations from ETH Zürich find that a single early-solar-system collision with a moon-sized body can simultaneously account for Venus' anomalous retrograde rotation and its absence of any natural satellite.
A preprint under review at Nature Communications suggests the target of China's sample-return mission may not be a fragment of the Moon - upending a key scientific assumption five days before orbit insertion.
