A New Kind of Amplifier

Marcus Woo

Researchers at Caltech and JPL have developed a new type of amplifier for boosting electrical signals. The device can be used for everything from studying stars, galaxies, and black holes to exploring the quantum world and developing quantum computers.

Peering Into the Heart of a Supernova

Kimm Fesenmaier

Using computer simulations, Caltech researchers have determined that if the interior of a dying star is spinning rapidly just before it explodes in a magnificent supernova, two different types of signals emanating from that stellar core will oscillate together at the same frequency.

Physicists Discover a New Particle that May Be the Higgs Boson

Marcus Woo

Physicists at the Large Hadron Collider (LHC) in Geneva, Switzerland, have discovered a new particle that may be the long-sought Higgs boson, the fundamental particle that is thought to endow elementary particles with mass.

Caltech at the LHC

Marcus Woo

Maria Spiropulu and Harvey Newman, both professors of physics at Caltech, lead the Caltech team of 40 physicists, students, and engineers that is part of the Compact Muon Solenoid (CMS) collaboration at the Large Hadron Collider (LHC) in Geneva, Switzerland.

X-ray Telescope Takes First Image

Marcus Woo

NASA's NuSTAR space telescope has taken its first image, snapping a shot of the high-energy X rays from a black hole in the constellation Cygnus. NuSTAR will explore black holes, the dense remnants of dead stars, energetic cosmic explosions, and even our very own sun.

JPL: Cassini Finds Probable Ocean Below Titan's Surface

Kimm Fesenmaier

By studying the way Saturn's moon Titan squeezes and stretches as it orbits the ringed planet, researchers using data from NASA's Cassini orbiter have determined that a layer of liquid water likely exists beneath the moon's frozen exterior.

The Physics of Going Viral

Kimm Fesenmaier

Caltech researchers have been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs.

NuSTAR Space Telescope Blasts Off

Marcus Woo

This morning, NASA's NuSTAR telescope was launched into the low-Earth orbit from which it will begin exploring the high-energy X-ray universe to uncover the secrets of black holes, the dense remnants of dead stars, energetic cosmic explosions, and even our very own sun.

Caltech Astronomer Mike Brown Awarded Kavli Prize in Astrophysics

Marcus Woo

Mike Brown, the Richard and Barbara Rosenberg Professor and professor of planetary astronomy at the California Institute of Technology (Caltech), has been named a co-winner of the 2012 Kavli Prize in Astrophysics for his efforts to understand the outer solar system—work that led to the demotion of Pluto.
