Researchers at the California Institute of Technology (Caltech) and NASA's Jet Propulsion Laboratory (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.

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. This could be a piece of "smoking-gun evidence" that would lead to a better understanding of supernovae.

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—short for Nuclear Spectroscopic Telescope Array—was launched on June 13, and is the first telescope that can focus high-energy X rays. It will explore black holes, the dense remnants of dead stars, energetic cosmic explosions, and even our very own sun.

In the biggest result of its kind in more than ten years, physicists have made the most sensitive measurements yet in a decades-long hunt for a hypothetical and rare process involving the radioactive decay of atomic nuclei. If discovered, the researchers say, this process could have profound implications for how scientists understand the fundamental laws of physics and help solve some of the universe's biggest mysteries.

In his Watson Lecture given on April 25, Shri Kulkarni, the John D. and Catherine T. MacArthur Professor of Astronomy and Planetary Science and the director of the Caltech Optical Observatories, described how Caltech's fully automated Palomar Transient Factory—Kulkarni calls it "Transients 'R' Us"—is revolutionizing how we explore the changing sky.

A team of astronomers has found that the most active galactic nuclei—enormous black holes that are violently devouring gas and dust at the centers of galaxies—may prevent new stars from forming. The team, which includes several researchers from Caltech, reported its findings in the May 10 issue of the journal Nature.
