Basin frequency and crater frequencies below 150 km indicate that the Moon has the oldest surface, Mercury has an intermediate age, and Mars has the youngest preserved terrain. An offset between the basin size-frequency distribution, the smaller crater size-frequency distribution and the main belt ...
The largest and youngest ones are quite hot, giving off a steady glow of warm light. From a distance, those stars would look indistinguishable from their stellar cousins, the red dwarfs. The smallest and oldest ones, by contrast, are barely visible, emitting radiation firmly in the infrared ...

As global field models are constructed to recreate the field at the core-mantle boundary, they have the potential to be used to understand the geodynamo and have been used to investigate core flow (Dumberry and Finlay 2007;Wardinski and Korte 2008;Livermore et al. 2014), with possible impl...
GEOMAGIA50.v3 is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data from a variety of materials that record Earth’s magnetic field over the past 50 ka. Since its original release in 2006, t
