NASA telescopes spotted a glowing nebula that looks like a guitar shredding rapid pulses of stellar material through space like sound waves through ... (also known as a pulsar) at the tip of ...

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these vibrations ...

from tests of alternate theories of gravity to constraints of extreme nuclear physics to the detection and characterization of low-frequency gravitational waves. Pulsar timing is also used to study ...

Since the discovery of this phenomenon in 2007, scientists have been trying to understand it, especially since this sound ... pulsar's magnetosphere. "If you have a screen and an electromagnetic ...

Combined, the pulsar observations construct a Galaxy-sized gravitational wave detector – spanning from the Earth to 25 carefully chosen pulsars across the Galaxy. This makes it possible to study ...
