quasars

What are quasars and active galactic nuclei?

Since the light arriving from the quasars began its journey billions of years ago.

来自类星体的光从数十亿年前就开始了它们的旅程,所以在宇宙诞生初期.

For many years, Treister says, astronomers doubted that obscured quasars were very common.

特雷斯特表示, 多年来天文学家们一直不相信被遮挡的类星体是很普遍的.

Quasars are the signatures of distant galaxies housing multi-spectral emanations outside our sphere of consciousness.

类星体是远端银河系的封印,蕴藏我们意识球体之外多重频谱的能量射线.

Quasars are optical and sources of enormous intensity, apparently at great distances from the earth.

类星体是极强的光源和射电源, 看上去距地球极其遥远.

The quasars cannot shine for longer than a few million years with their present luminosity.

在几百万年以后,类星体将不可能具有他们今天那样的发光度.

This paper presents a novel method for redshift determination of quasars.

The discovery of quasars refuted the Steady State theory.

类星体的发现否定了稳恒态理论.

They have discovered now, previously unimagined objects-pulsars, quasars, and black holes.

Among 518 bright sources ( S 5 Ghz ≥1 . OJy ) at 5 GHz, at least 291 ( ≥56 % ) of them are known as being quasars.

更有趣的是,518个5GHz亮 射电源中 ( S5GHz≥1.0Jy ), 至少有291个 ( ≥56% ) 是类星体.

They have discovered now , previou sly unimagined objects-pulsars, quasars, and black holes.
