Because they spin. The radiation is directional and sweeps across the universe. A relatively stationary observer sees the pulsar as an off/on phenomenon.

What is the name to neutron stars that give off pulses of radio waves?

A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar spins. When those beams flash over Earth, we see them as regular, repeating pulses of radio emission.


Are pulsars found in supernova remnants.?

Yes, pulsars are often found in supernova remnants. Pulsars are rapidly rotating neutron stars that emit beams of radiation, and they are formed when a massive star undergoes a supernova explosion. The remnants of the supernova provide the environment from which the pulsar originates.


Some neutron stars that emit pulses of radiation called?

Some neutron stars that emit pulses of radiation are known as pulsars. Pulsars rotate rapidly and emit beams of electromagnetic radiation from their magnetic poles, which are observed as regular pulses when they sweep across the Earth.


Who was the female british astronomer who helped discover pulsars?

Pulsars were discovered by accident in 1967 when Jocelyn Bell, working with Antony Hewish were looking for twinkling sources of radio radiation.


Are quasars and pulsars visible to the naked eye?

No, quasars and pulsars are not visible to the naked eye from Earth. Quasars are extremely distant and faint celestial objects, while pulsars are neutron stars that emit beams of electromagnetic radiation which are not usually visible to the human eye. Both require specialized equipment for observation.

Why aren't all neutron stars seen as pulsars?

Not all neutron stars are seen as pulsars because pulsars emit beams of radiation that are only visible if they are pointed towards Earth. If a neutron star's beams are not aligned with our line of sight, it will not appear as a pulsar.

Do all objects give off pulsars?

Pulsars are highly magnetized, rotating Neutron_starthat emit a beam of Electromagnetic_radiation. The radiation can only be observed when the beam of emission is pointing towards the Earth. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name


How did flash floods get their name?

Flash floods are floods that happen quickly and without warning. Like they appear in a "flash".


Where are pulsars located in space?

Pulsars are located every where around the universe keep in mind pulsars are neutron stars so that means they were formed by large stars that have aged and died out

How are pulsars related to supernovas?

Pulsars are formed during a supernova event when a massive star explodes, leaving behind a dense core called a neutron star. As this neutron star rotates rapidly, it emits beams of radiation that we detect as pulses, hence the name "pulsars." So, pulsars are directly related to the remnants of supernova explosions.
