Question

Quizplus · Accepted Answer

The X-ray image is showing emission from a neutron star, which is a highly dense and compact object formed by the collapse of a massive star. Pulsars, another type of compact object, are also neutron stars that emit regular bursts of radio waves, but this X-ray image does not show evidence of pulsations. White dwarfs, on the other hand, are less massive and less dense than neutron stars, and they emit mainly in the ultraviolet and optical bands. Black holes cannot be directly imaged, as they do not emit light, but their presence can be inferred from the effects of their gravity on surrounding matter. Therefore, option B is the best choice.
