Tracing the Roots of the California Condor

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.

Caltech's Ingersoll Receives Achievement Award

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.

New Method of Studying Ancient Fossils Points to Carbon Dioxide As a Driver of Global Warming

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.

Caltech, JPL, Northrop Grumman to Celebrate 50 Years of Space Exploration

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.

NASA'S Spitzer Finds Water Vapor on Hot, Alien Planet

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.

The Dwarf Planet Known as Eris is More Massive than Pluto, New Data Shows

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.

Caltech Astrophysicist Peter Goldreich Wins $1 Million International Shaw Prize

Peter Goldreich, the Lee A. DuBridge Professor of Astrophysics and Planetary Physics, Emeritus, has been named winner of the 2007 Shaw Prize for astronomy by the Shaw Prize Foundation of Hong Kong. The announcement was made Tuesday, June 12, at foundation headquarters in Hong Kong.

Caltech Seismologist Hiroo Kanamori Awarded Kyoto Prize by Inamori Foundation

Hiroo Kanamori, one of the world's leading authorities on earthquakes, has been awarded the 23rd annual Kyoto Prize by the Inamori Foundation of Japan. The announcement was made today in Kyoto.

Astronomers Find Their Third Planet With Novel Telescope Network

Astronomers using the Trans-atlantic Exoplanet Survey (TrES) network of small telescopes are announcing today their discovery of a planet twice the mass of Jupiter that passes in front of its star every 31 hours. The planet is in the constellation Hercules and has been named TrES-3 as the third planet found with the TrES network.

Some Earth-like Worlds May Have Foliage of Colors Other Than Green, Researchers Say

In the next decade, when scientists are able to study Earth-sized worlds around other stars, they may find that foliage on some of the planets is predominantly yellow—or orange, or red. It all depends on the color of the star the planet orbits and the stuff that makes up the planet's atmosphere.
