How the Grand Canyon was carved has been a topic of scientific controversy for nearly 140 years. Now, with new geochronologic data from the canyon and surrounding plateaus, geologists from the California Institute of Technology present significant evidence that the canyon formed nearly 50 million years earlier than previously thought.

Water is an essential ingredient for forming planets, yet has remained hidden from scientists searching for it in protoplanetary systems, the spinning disks of particles surrounding newly formed stars where planets are born. Now the detection of water vapor in the inner part of two extrasolar protoplanetary disks brings scientists one step closer to understanding water's role during terrestrial planet formation.

Sebastien Leprince, a graduate student in electrical engineering at the California Institute of Technology, working under the supervision of geology professor and director of Caltech's Tectonics Observatory (TO), Jean-Philippe Avouac, wrote software that correlates any two optical images taken by satellite. It has proved extremely reliable in tracking large-scale changes on Earth's surface, like earthquake ruptures, the mechanics of "slow" landslides, or defining the fastest-moving sections of glaciers that, due to global warming, have recently increased their pace.

Recent research spearheaded by Jean-Philippe Avouac, professor of geology and director of the Tectonics Observatory at the California Institute of Technology, shows that in the Himalayan mountains, at least, there is indeed an earthquake season. It's winter.

At the end of the Pleistocene epoch some 10,000 years ago, two species of condors in California competed for resources amidst the retreating ice of Earth's last major glacial age. The modern California condor triumphed, while its kin expired.

Andrew P. Ingersoll of the California Institute of Technology has been awarded the 2007 Gerard P. Kuiper Prize by the Division for Planetary Sciences (DPS) of the American Astronomical Society in honor of his outstanding contributions to planetary science. The award was presented this week during the annual DPS meeting in Orlando, Florida.

A team of American and Canadian scientists has devised a new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils. The first published tests with the method further support the view that atmospheric CO2 has contributed to dramatic climate variations in the past, and strengthen projections that human CO2 emissions could cause global warming.

Before October 1957, space flight was a thing of fantasy. Today we are experienced space explorers with unlimited voyages to undertake. Where is space flight's next horizon? What constitutes sensible space investment? How did the space pioneers accomplish their goals? These topics will be addressed at "50 Years in Space: An International Aerospace Conference Celebrating 50 Years of Space Technology," which will take place from September 19 to 21 at the California Institute of Technology.

The exoplanet HD 189733b has just been found to have water vapor in its atmosphere. The observation provides the best evidence to date that water exists on worlds outside our own solar system.

Die-hard Pluto fans still seeking redemption for their demoted planet have cause for despair this week. New data shows that the dwarf planet Eris is 27 percent more massive than Pluto, thereby strengthening the decree last year that there are eight planets in the solar system and a growing list of dwarf planets.
