Pulsars
A pulsar is nothing more than a young neutron star, with a pole that points towards Earth.
245 Questions
Where in the electromagnetic spectrum are pulsars best observed?
Asked by Hernandez1218
Pulsars are best observed in the radio part of the electromagnetic spectrum. This is because their strong radio emission allows them to be detected and studied using radio telescopes. However, pulsars have also been observed at other frequencies, including X-ray and gamma-ray wavelengths.
What is periodic signal?
Asked by Wiki User
A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.
What types of technologies has best helped scientists to study very high-energy objects in outer space such as exploding supernovae black holes and pulsars?
Asked by Wiki User
radio telescopes
Where does the energy of a pulsar came from?
Asked by BryanJames16
The energy of a pulsar comes from within, from the nucleus.
What does a pulsar emit to prove its existence?
Asked by Wiki User
Humans are able to detect pulsars when one of their beams crosses paths with the Earth. When this happens, we are able to detect the resulting electromagnetic radiation in the radar spectrum.
Was a pulsar discovered near the sun?
Asked by Wiki User
Doubtful. The nearest pulsar to us is Geminga at over 815 light years or PSR J0437-4715 at 510 light years.
What is the furthest man has ever seen into space?
Asked by Wiki User
The farthest objects detected are estimated to lie at distances of something like
14 billion light years from us.
But it must be noted that measuring those distances takes a lot of ingenuity,
and there are still a lot of questions among serious cosmologists regarding
the accuracy of today's best estimates.
What kind of electromagnetic radiation do pulsars emit?
Asked by Wiki User
All electromagnetic wave lengths (light)
Why did astronomers conclude that pulsars could not be pulsating stars?
Asked by Wiki User
Pulsars have extremely short periods; in some cases seconds, in some cases just a few milliseconds. There is no way a typical star, with its great size (for example, a diameter of 1.4 million kilometers in the case of our Sun) can pulsate that quickly.
