The face that the Moon shows to Earth looks far different from the one it hides on its far side. The nearside is dominated by the lunar mare - the vast, dark-colored remnants of ancient lava flows. The crater-pocked far side, on the other hand, is virtually devoid of large-scale mare features. Why the two sides are so different is one of the Moon's most enduring mysteries.
Now, researchers ... more |

In 2006, the Cassini spacecraft recorded geyser curtains shooting forth from "tiger stripe" fissures near the south pole of Saturn's moon Enceladus - sometimes as much as 200 kilograms of water per second. A new study suggests how expanding ice during millennia-long cooling cycles could sometimes crack the moon's icy shell and let its inner ocean out, providing a possible explanation for the gey ... more |

In machine learning, understanding why a model makes certain decisions is often just as important as whether those decisions are correct. For instance, a machine-learning model might correctly predict that a skin lesion is cancerous, but it could have done so using an unrelated blip on a clinical photo.
While tools exist to help experts make sense of a model's reasoning, often these method ... more |
