Astronomers know numerous details about prospective targets for space exploration, such as for example the surface of Mars, but they cannot test technologies they want to send there directly. Fortunately, they had two deserts on Earth that they can use as analogs for those environments. Readings collected by rovers, ... |

Antarctica was until recently the most pristine continent in the world, but that situation is currently changing. Research scientists, tourists, and just about anyone who sets foot around the South Pole, are carrying bacteria and other organisms that are not indigenous to this area. For all intents and purposes, we a... |

For decades, climate scientists have believed that ice sheets and caps only grow as snow that accumulates on top gets pressed by other layers of snow, and turned into ice. But this view is now being disproved by a new study, which finds that ice can also form at the bottom of sheets and caps.This was discovered by ex... |
