Seismic waves are shock waves that propagate through Earth's layers after an earthquake or explosive event, traveling at different speeds depending on the density and state of the material.

Urban particles shape climate by influencing clouds and radiation. Vertical monitoring reveals overlooked impacts.

To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

Bubbles of different concentrations and multiple kinds of gas at different layers can be matched with climate activities that we know happened at different periods of time. By analyzing those bubbles, ...

The team used data from seismic waves—energy waves that travel through the Earth after earthquakes—to study the inner core. They found that these waves travel at different speeds in different ...

Earth has experienced climate change in the past without help from humanity. We know about past climates because of evidence left in tree rings, layers of ice in glaciers, ocean sediments, coral reefs ...

In 2019 we published this side-by-side comparison of Jupiter and Earth. The image of Jupiter (left) shows ammonia-rich clouds swirling in the outermost layers of the planet’s atmosphere ... Siegelman ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Like a moth in a cocoon, the metamorphosis of Earth's crust from molten goop to solid land is hidden from view, leaving ...
