Cross-section of the Earth (left) and the exoplanet Kepler-138 d (right). Like the Earth, this exoplanet has an interior composed of metals and rocks (brown portion), but Kepler-138 d also has a thick ...

Cartoon cross section of the Earth showing the mantle, outer core and inner core. Convection in the outer core produces Earth's geomagnetic field. The properties of Earth’s iron-rich core are key to ...

Figure 1: Neutrino cross-section measurements. Our measurement uses naturally occurring atmospheric and astrophysical neutrinos to extend neutrino interaction cross-section measurements to ...
