从可见光扩展到无线电波，再到X 射线和伽马射线，天文学总是会发现不寻常的物体，如射电星系、类星体和脉冲星。
The extension of astronomy from visible light to radio waves to x-rays and gamma rays never failed to lead to the discovery of unusual objects such as radio galaxies, quasars, and pulsars.
类星体是“类似恒星射电源”的缩写。
本文对有射电子源结构类星体的红移、视星等关系进行了统计研究。
In this paper a statistical investigation has been made on the redshift-magnitude relation of quasars with radio components structure.
这种物体多数是一个发射巨大能量（包括射电、红外线、紫外线、X射线和伽玛射线在内）的类星体。
The most powerful such object is a quasar, which emits a huge amount of radio, infrared, ultraviolet, X-ray, and gamma-ray energy.
类星体是“类似恒星射电源”的缩写。
