Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active subduction zones come into being, ...

In between Earth's rigid tectonic plates above and its convecting mantle below is a hot and soft layer known as the asthenosphere. At mid-ocean ridges, upwelling of the hot asthenosphere to the surface of the seafloor forms ...

NASA's James Webb Space Telescope will see the first galaxies to form after the Big Bang, but to do that, its instruments first need to get cold—really cold. On April 7, Webb's Mid-Infrared Instrument (MIRI)—a joint development ...
