3D-Model mimics volcanic explosions

(PhysOrg.com) -- A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify of blast zones ...

Juno reveals a giant lava lake on Io

NASA's Juno spacecraft came within 1,500 km (930 miles) of the surface of Jupiter's moon Io in two recent flybys. That's close enough to reveal new details on the surface of this moon, the most volcanic object in the solar ...

Earth's core has been leaking for billions of years

Earth's magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source of this magnetic field is the core at the centre of our planet.

How to study high-speed flows

Joanna Austin (MS '98, PhD '03) does not just go with the flow. She picks it apart and analyzes it. One of the newest faculty members in Caltech's Division of Engineering and Applied Science is a gas dynamicist, Austin studies ...

Past decade saw unprecedented warming in the deep ocean

From 1975 on, the global surface ocean has shown a pronounced-though wavering-warming trend. Starting in 2004, however, that warming seemed to stall. Researchers measuring the Earth's total energy budget-the balance of sunlight ...
