New discovery may offer clues to 'missing' pulsars

Millisecond pulsars (MSPs) are evolved neutron stars with short spin periods that have gone through a long period of mass transfer in a low-mass X-ray binary phase. Globular clusters (GCs)—conglomerations of tens of thousands ...

First-ever detection of gas in a circumplanetary disk

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) and partners at the National Radio Astronomy Observatory (NRAO) have made the first-ever detection of gas in an circumplanetary disk. What's more, the ...

Radio

Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, or phase. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.
