Stellar Death Caught in the Act

Astronomers for the first time have caught a star in the act of exploding. Astronomers have previously observed thousands of stellar explosions, known as supernovae, but they have always seen them after the fireworks were well underway.

Thirty-Meter Telescope Focuses on Two Candidate Sites

After completing a worldwide survey unprecedented in rigor and detail of astronomical sites for the Thirty-Meter Telescope (TMT), the TMT Observatory Corporation board of directors has selected two outstanding sites, one in each hemisphere, for further consideration. Cerro Armazones lies in Chile's Atacama Desert, and Mauna Kea is on Hawai'i Island.

Caltech Helps Open the Universe in "WorldWide Telescope"

Panoramic images of the sky obtained at Palomar Observatory and by the Two Micron All Sky Survey (2MASS), plus pointed observations from the Spitzer Space Telescope, form a significant part of the "World Wide Telescope" (WWT), a new product released today by Microsoft aimed at bringing exploration of the Universe and its many wonders to the general public.

A New Take on Microbrewing

Since Babylonian times, a still has provided the means to turn grain, fruit, or vegetables into an intoxicating drink. Today, a still may provide a solution to the more complex problem of how to detect diseases.

Physicists Transcribe Entanglement into and out of a Quantum Memory

Scientists at the California Institute of Technology have laid the groundwork for a crucial step in quantum information science. They show how entanglement, an essential property of quantum mechanics, can be generated between beams of light, stored in a quantum memory, and mapped back into light with the push of a button.

High-Speed Data Transfer System Garners Outreach Award

The Corporation for Education Network Initiatives in California (CENIC) has rewarded researchers at the California Institute of Technology for better connecting physicists worldwide. Lead project scientist Harvey Newman, professor of physics at Caltech, Julian Bunn of the Caltech Center for Advanced Computing Research, and their international team of researchers will receive a trophy for Innovations in Networking at a ceremony in Oakland, California, on March 11.

U. S. Experiment Takes the Lead in the Competitive Race to Find Dark Matter

Scientists of the Cryogenic Dark Matter Search (CDMS) experiment, including researchers from the California Institute of Technology, today announced that they have regained the lead in the worldwide race by a number of different research groups to find the particles that make up dark matter. The CDMS experiment, which is being conducted a half-mile underground in a mine in Soudan, Minnesota, again sets the world's best constraints on the properties of dark matter candidates.

Sixth Annual Caltech Science Writing Symposium

California Institute of Technology President Jean-Lou Chameau and Pulitzer Prize-winning journalist Usha Lee McFarling will be the featured speakers at the sixth annual Caltech Science Writing Symposium. The topic of their conversation will be the importance and challenges of communicating science to the general public.

Physicist Hirosi Ooguri Awarded for Novel Research on Black Holes

Hirosi Ooguri, the Kavli Professor of Theoretical Physics at the California Institute of Technology, is a corecipient of the first ever Leonard Eisenbud Prize for Mathematics and Physics, awarded by the American Mathematical Society (AMS). The prize, created in 2006, has gone to Ooguri and coauthors Andrew Strominger and Cumrun Vafa of Harvard University for their paper "Black hole attractors and the topological string," published in 2004.

LIGO Sheds Light on Cosmic Event

An analysis by the international LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration has excluded one previously leading explanation for the origin of an intense gamma-ray burst that occurred last winter. Gamma-ray bursts are among the most violent and energetic events in the universe, and scientists have only recently begun to understand their origins.
