How this robot could accelerate the search for life
Planetary rovers may seem like bold explorers, but in reality they work under tight limits. On Mars, even simple instructions take minutes to arrive, so every move must be planned carefully. That keeps missions safe, but it also raises a question: if robots move slowly and stop often, how much of another world can we really study?

A young solar system does not just build planets from dust and gas. It can also be shaped by what happens nearby, including the death of a massive star. New research suggests that a supernova at the right distance could quietly change a planet’s ingredients from the start, and that this setup may be more common than scientists once assumed.
