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 ...

The geocentric model is a debunked theory that the Earth is the center of the universe, with the sun and planets revolving around it. When you purchase through links on our site, we may earn an ...

The Earth and its Moon are very similar in composition, a fact that's neatly explained by the idea that the two formed from the shared debris of a collision between the early Earth and a Mars-sized ...

As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these ...
