quasar 是什么意思

音标：[ 'kweisɑ: ]

中文翻译与英英解释

	n. 【天文学】类星体；类星射电源。

a starlike object that may send out radio waves and other forms of energy; many have large red shifts
同义词：quasi-stellar radio source,

A quasi-stellar radio source ("quasar") is a very energetic and distant active galactic nucleus. Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that were point-like, similar to stars, rather than extended sources similar to galaxies.
