WebThe temperature of the photosphere is around 5,500 °C (9,900 °F), which is much cooler than the Sun's core. Most of the light energy produced in the Sun’s core escapes from the photosphere. Because the plasma is cooler and less dense at the surface, there are fewer collisions to trap the energy carrying photons within the Sun. Web13 feb. 2024 · New theory explains how Earth’s inner core remains solid despite extreme heat Seismic waves traveling in between the Earth's poles travel faster than those between the equator - one sign of the textured nature of Earth's solid iron inner core. A recent study from KTH explains how the core retains its unique solid form. (Image: Dixon Rohr)
