The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.
Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other space telescopes ...
While radio waves emitted by radio and television broadcasting and CB radio can disrupt the magnetic compass of migratory birds, those used in mobile communication networks do not because the ...
This spring, the University of Notre Dame welcomes the development of a critical strategy at the national level. It’s about the radio frequency spectrum, the natural resource used by all sorts of high ...
Like light waves, radio frequency energy tends to travel in a straight line. In the lower frequencies, radio waves that shoot skyward bounce back from electrically charged layers of the upper ...
We have just published evidence in Nature Astronomy for what might be producing mysterious bursts of radio waves coming from distant galaxies, known as fast radio bursts or FRBs. Two colliding neutron ...
