Sentences with phrase «emitting radio pulses»

Pulsars, aka spinning neutron stars, normally emit radio pulses like clockwork.

Not exact matches

Katelin Schutz, a theorist at the University of California, Berkeley, says that clarity could come even faster from stellar beacons called millisecond pulsars, which emit exquisitely regular pulses of radio waves.

In 1974, astronomers Russell Hulse and Joseph Taylor detected a binary pulsar, a pair of two dead stars emitting pulses of radio waves.

The nebula contains a pulsar in its centre which rotates thirty times per second, emitting pulses of radiation from gamma rays to radio waves.

Like turning the knob on a radio, the team adjusted the pulse so that, if the artificial horizon emitted any Hawking radiation, its wavelength would be between 800 and 900 nanometers, a range that could not be confused with other sources such as laser - induced fluorescence.

Radar pulses (short bursts of radio - frequency energy) emitted from a ground - based transmitter are reflected by a meteor's trail.

Although neutron stars were predicted in the 1930s, it was not until the late 1960s that observers accidentally discovered a radio source emitting weak pulses, each lasting about 0.3 second with a remarkably constant period of approximately 1.337 seconds.

Pulsars are compact, rotating neutron stars that act like cosmic lighthouses and emit regular radio pulses whose periods can be measured very precisely.

But instead of pulses of sound or radio waves, a LIDAR scanner emits laser beams and measures the time that they take to return in order to map the location and elevation of objects in the surrounding area.
