Many life-bearing planets could exist in interstellar space, according to Caltech planetary science professor

Long ago in a solar system not at all far away, there could have existed about five to 10 Earth-like planets in Jupiter-crossing orbits.

Lack of Energy Makes Life on Europa Unlikely, Caltech Study Concludes

Robert Tindol
A new study conducted by California Institute of Technology and Jet Propulsion Laboratory scientists shows that the Europan ocean is unlikely to harbor any life form more complex than single-celled organisms—and maybe not even that.

Mars Global Surveyor's triumphs follow recovery from ill-fated earlier mission

Robert Tindol

Arden Albee is often asked how it felt to lose the Mars Observer.

Aeronautics researchers generate cracks that move as fast as the speed of sound, and resemble certain earthquake shear ruptures

Aeronautics researchers generate cracks that move as fast as the speed of sound, and resemble certain earthquake shear ruptures

Robert Tindol

New work from California Institute of Technology researchers shows that a certain type of crack can exceed the shear wave speed through the material, creating a sort of "sonic boom," and can almost reach sound speed.

Earth's water probably didn't come from comets, Caltech researchers say

Robert Tindol
A new Caltech study of comet Hale-Bopp suggests that comets did not give Earth its water, buttressing other recent studies but contrary to the longstanding belief of many planetary scientists.

SCE Joins Caltech in Seismic Program to Improve Quake Response

Sonia Chernobieff

ROSEMEAD, Calif., Jan. 15, 1999—On the eve of the fifth anniversary of the devastating Northridge earthquake, Southern California Edison and the California Institute of Technology today announced the utility's participation in a state-of-the-art seismic measuring network that will expedite power restoration and emergency response after a major temblor in the southland.

New study explains motions of the Emerson fault in the years following the Landers earthquake

Robert Tindol
For geophysicists, the 7.3–magnitude Landers earthquake of June 28, 1992 has yielded much in terms of understanding the basic mechanisms of seismic events. A new study appearing in this week's Science provides a new model to explain why the ground near the fault gradually shifted the first few years after the main shock. The work could be used in the future for the analysis of earthquake hazard.?

Galileo data shows Jupiter's lightning associated with low-pressure regions

Robert Tindol

Images of Jupiter's night side taken by the Galileo spacecraft reveal that the planet's lightning is controlled by the large-scale atmospheric circulation and is associated with low-pressure regions.
