An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a Sun-like star, ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The Earth's interior is composed of four layers ... Above the inner core is the outer core, a shell of liquid iron. This layer is cooler but still very hot, perhaps 7,200 to 9,000 degrees ...

When and where will the total lunar eclipse be visible? We show who will have the best views and when you should watch.

Emission spectra of two iron ions, Fe IX and Fe X, are particularly useful for studying the sun's outer atmosphere. However, both of these spectra contain emission lines that can't yet be matched ...
