The rocks explored by the Curiosity Rover in Gale Crater are sure signs of the past presence of water on the red planet, but how did they form? The prevailing view has been a long-lasting lake environment, potentially suitable for life, but today’s paper offers a much more dramatic explanation.
Where do interstellar objects come from? And how many should we expect to find every year?
