A new study by NIST physicists shows that clocks on Mars run about 477 microseconds faster per day than identical clocks on Earth. The difference comes from Mars’s weaker gravity, orbital eccentricity, and gravitational influences across the solar system. Though tiny, this daily time lead will pose challenges for future Mars navigation and communication networks, re…

A new analysis of Apollo samples and Earth rocks suggests that a nearby rocky planet, not a distant object, collided with early Earth and formed the moon. The study argues that this lost planet, Theia, originated in the inner solar system and shared Earth’s early neighbourhood, offering fresh insight into one of the most important events in our planet’s history.
