World Network Speed Record Shattered for Third Consecutive Year

Caltech, SLAC, Fermilab, CERN, Michigan, Florida, Brookhaven, Vanderbilt and Partners in the UK, Brazil, Korea and Japan Set 131.6 Gigabit Per Second Mark During the SuperComputing 2005 Bandwidth Challenge

Watson Lecture: Exploring Einstein's Legacy

November 25 marks the 90th anniversary of Einstein's formulation of his theory of general relativity, which describes gravity as a consequence of the warping of space and time.

Survey of Early Universe Uncovers Mature Galaxy Eight Times More Massive Than Milky Way

A massive galaxy seen when the universe was only 800 million years old has been discovered by teams of astronomers using NASA's Spitzer and Hubble Space Telescopes.

Most Distant Explosion in Universe Detected; Smashes Previous Record

Scientists using the NASA Swift satellite and several ground-based telescopes, including Palomar Observatory's robotic 60-inch telescope, have detected the most distant explosion yet, a gamma-ray burst from the edge of the visible universe.

Caltech Scientists Create Tiny Photon Clock

In a new development that could be useful for future electronic devices, applied physicists at the California Institute of Technology have created a tiny disk that vibrates steadily like a tuning fork while it is pumped with light. This is the first micro-mechanical device that has been operated at a steady frequency by the action of photons alone.

KamLAND Detector Provides New Way to Study Heat from Radioactive Materials Within Earth

Much of the heat within our planet is caused by the radioactive decay of the elements uranium and thorium. Now, an international team of particle physicists using a special detector in Japan has demonstrated a novel method of measuring that radioactive heat.

Researchers devise plasma experiment that shows how astrophysical jets are formed

Applied physicists at the California Institute of Technology have devised a plasma experiment that shows how huge long, thin jets of material shoot out from exotic astrophysical objects such as young stars, black holes, and galactic nuclei.

Andromeda Galaxy Three Times Bigger in Diameter Than Previously Thought

Scott Chapman, from the California Institute of Technology, and Rodrigo Ibata, from the Observatoire Astronomique de Strasbourg in France, have led a team of astronomers in a project to map out the detailed motions of stars in the outskirts of the Andromeda galaxy. Their recent observations with the Keck telescopes show that the tenuous sprinkle of stars extending outward from the galaxy are actually part of the main disk itself.

Four from Caltech Named to National Academy of Sciences

Three members at the California Institute of Technology faculty and one former faculty who is now a visiting associate are among the 72 new members and 18 foreign associates being named to the National Academy of Sciences today. The election was announced during the 142nd annual meeting of the Academy in Washington, D.C.

Five from Caltech Faculty Elected to American Academy of Arts and Sciences

Five faculty members at the California Institute of Technology are among this year's newly elected fellows of the American Academy of Arts and Sciences. They join 191 other Americans and 17 foreign honorees as the 225th class of fellows of the prestigious institution that was cofounded in 1780 by John Adams.
