If you were to look at your standard-fare pulsar star, what color would it appear?

1 Answer

Blue/white

Explanation:

Pulsars are neutron stars that rotate rapidly and eject a cone of electromagnetic radiation. When that cone sweeps past the Earth, we detect it as a "pulse" and thus the name pulsar.

The electromagnetic jet was initially discovered in the radio wave frequency but other pulsars have been found in many different EM wavelengths, including X-rays.

The colour of the pulsar itself, as best as I can discover, would appear to be blue/white.
