Biggest Stars Produce Strongest Magnets
Source: CFA Harvard Posted: 1/31/05 Astrophysicists have announced that they have linked two of astronomy's extremes, showing that some of the biggest stars in the cosmos become the strongest magnets when they die.
Lab Experiments Mimic a Star's Energy Bursts
Source: NIST Posted: 1/30/05 A key process that enhances the production of nuclear energy in the interior of dense stars has been re-created in the laboratory for the first time by physicists at the National Institute of Standards and Technology (NIST).
Laser Applications Heat Up for Carbon Nanotubes
Source: NIST Posted: 1/30/05 Carbon nanotubes—a hot nanotechnology with many potential uses—may find one of its quickest applications in the next generation of standards for optical power measurements.
Spacetime wave orbits black hole
Source: MIT Posted: 1/12/05 Astronomers from MIT and the Harvard-Smithsonian Center for Astrophysics have seen evidence of hot iron gas riding a ripple in spacetime around a black hole. This spacetime wave, if confirmed, would represent a new phenomenon that goes beyond Einstein's general relativity.
Chip-Scale Magnetic Sensor Draws on Mini Clock Design
Source: NIST Posted: 1/4/05 A low-power, magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas—a million times weaker than the Earth's magnetic field—has been demonstrated by researchers at the NIST.
Saturn’s Outer Rings May Be Eroding
Source: USC Posted: 1/2/05 The planet’s E ring could disappear within 100 million years, based on images captured by the Cassini spacecraft.
