observable stochastic background of gravitational waves that impresses a faint polarized signature on the CMB. The National Research Council’s decadal survey recommended...
lightning structure within a storm. One method is to use multiple receivers to measure differences in the arrival times of the radio impulses. Zen Kawasaki of Osaka...
brilliant star that was not in previous images. This was dubbed SN1998bw. At such close range, GRB980425 could only have about 1 percent of 1 percent (0.0001) of the raw...
wavelengths and high energies. Telescopes rely on the interaction between energy and matter. The atomic matter that forms the telescope has to somehow interpret the energy...
and their interaction with Earth and other planets, as well as with the interstellar medium. Investigations of the physics of magnetospheres, including fundamental...
seismic waves from earthquakes to probe inside Earth. In this way, mission scientists hope to map the ebb and flow of the sun's inner magnetic dynamo, the root of all solar...
that's not all -- they also reflect radio waves. During a shower like the Leonids, radio signals from TV stations, RADAR facilities, and AM/FM transmitters are constantly...
. The luminous ionized trails are not only visually striking -- they also reflect radio waves. During a major meteor shower, radio signals from TV stations, RADAR facilities...
helioseismology, which can probe conditions within the Sun much like seismic waves reveal the interior structure of our planet, announced that currents of gas at the base of...
. Activities include Earth System in a Bottle and We're All Connected: Earth System Interactions. Visualize waves with an interactive tool that allows students to control...
