A Nasa spacecraft has found further tantalising evidence for the existence of water ice at Mercury's poles.
Though surface temperatures can soar above 400C, some craters at Mercury's poles are permanently in shadow, turning them into so-called cold traps.
Previous work has revealed patches near Mercury's poles that strongly reflect radar - a characteristic of ice.
