Gravity Measurements Confirm Subsurface Ocean on Enceladus

Using gravity measurements collected by NASA's Cassini spacecraft, scientists have confirmed that Saturn's moon Enceladus harbors a large subsurface ocean near its south pole, fueling plumes first seen in 2005.

When Rocks Roll: How Sediment Transport Shapes Planetary Surfaces

On Wednesday, March 19, Professor of Geology Michael Lamb will describe how flowing water and grains of sand create Earth's dramatic landscapes.

Airborne Over Iceland: Charting Glacier Dynamics

Mark Simons, professor of geophysics at Caltech, along with graduate student Brent Minchew, recently logged over 40 hours of flight time mapping the surface of Iceland's glaciers. Flying over two comparatively small ice caps, Hofsjökull and Langjökull, they traveled with NASA pilots and engineers in a retrofitted Gulfstream III business jet, crisscrossing the glaciers numerous times.

Caltech Appoints Diana Jergovic to Newly Created Position of Vice President for Strategy Implementation

In the newly created position, Jergovic will collaborate closely with the president and provost, and with the division chairs, faculty, and senior leadership on campus and at the Jet Propulsion Laboratory, to execute and integrate Caltech's strategic initiatives and projects and ensure that they complement and support the overall education and research missions of the campus and JPL. This appointment returns the number of vice presidents at the Institute to six.

Michael Gurnis Receives Geology Award

The American Association of Petroleum Geologists (AAPG) named Michael Gurnis, Caltech's John E. and Hazel S. Smits Professor of Geophysics, a 2014 recipient of the Wallace E. Pratt Memorial Award.

Detection of Water Vapor in the Atmosphere of a Hot Jupiter

Researchers at Caltech and several other institutions have made the first detection of water in the atmosphere of a Jupiter-mass planet orbiting the nearby star tau Boötis.

The First 50 Years of Planetary Science

If you ask Andy Ingersoll how Caltech has contributed to our understanding of the universe, he will tell you, "Caltech invented planetary science!" And since the field's origins just fifty years ago, Caltech has become one of the top centers of planetary science research in the world.

Is Natural Gas a Solution to Mitigating Climate Change?

Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. But where is the methane coming from? Research by atmospheric chemist Paul Wennberg of the California Institute of Technology (Caltech) suggests that losses of natural gas—our "cleanest" fossil fuel—into the atmosphere may be a larger source than previously recognized.

Caltech's "Secrets" to Success

Everyone who really knows Caltech understands that it is unique among universities around the world. But just what makes Caltech so special? We've asked that question before, and the numbers don't tell the full story. So, is it our focus? Our culture? Our people?

From Rivers to Landslides: Charting the Slopes of Sediment Transport

In the Earth Surface Dynamics Lab at Caltech the behavior of rivers is modeled through the use of artificial rivers—flumes—through which water can be pumped at varying rates over a variety of sediments while drag force and acceleration are measured.
