Editor’s note: when we start to examine other worlds more closely we are going to need tools that allow us to get the best possible understanding of those worlds’ construction […]
![(a) Top panel shows [Eu/α] independent of the temperature bias as a function of [α/H]. Small orange triangles represent data from DM and small green triangles represent data from BB. The cross matched sample of 68 stars described in Section 3.1 is shown in big red squares. Stars from the solar twins analysis by Spina et al. (2018), Bedell et al. (2018) are shown as big blue circles. A black star is used to represent the solar abundance value. The red dashed line at [Eu/α] = 0.06 represents the critical value for an extended dynamo failure given by the model from Nimmo et al. (2020). Outliers in [Eu/H] abundances discussed in Section 6.2 are outlined in black. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/Distribution-of-Europium.png?resize=1200%2C711&ssl=1)
The energy provided in the radioactive decay of thorium (Th) and uranium (U) isotopes, embedded in planetary mantles, sustains geodynamics important for surface habitability such as the generation of a […]
Beryllium-10, a rare radioactive isotope produced by cosmic rays in the atmosphere, provides valuable insights into the Earth’s geological history.
We’ve all seen the surreal footage in nature documentaries showing hydrothermal vents on the frigid ocean floor—bellowing black plumes of super-hot water—and the life forms that cling to them. Now, […]
In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a University of […]
