Mars' north pole contains a large ice cap made up of many layers of frozen water. Like ice cores on Earth, those layers offer a tantalizing record of climate on Mars over the past several million years. The first step in ...

Nearly every atmospheric science textbook ever written will say that hurricanes are an inherently wet phenomenon—they use warm, moist air for fuel. But according to new simulations, the storms can also form in very cold, ...

A new study reveals asteroid impacts on ancient Mars could have produced key ingredients for life if the Martian atmosphere was rich in hydrogen. An early hydrogen-rich atmosphere on Mars could also explain how the planet ...
