Explanation: What did the first quasars look like? The nearest quasars are now known to be
supermassive black holes in the centers of galaxies. Gas and dust that falls toward a quasar
glows brightly, sometimes outglowing the entire home galaxy. The quasars that formed in the
first billion years of the universe are more mysterious, though, with even the nature of the
surrounding gas still unknown. Above, a |

Seattle (January 8th, 2007) Astronomers using the W. M. Keck Observatory
have discovered a triple quasar.
Quasars are powerful sources of electromagnetic energy, which includes radio
waves and light. They are believed to be powered by supermassive black
holes in the centers of galaxies.
While roughly 100,000 quasars and dozens of double quasars have been
observed in recent years, the discovery by scientists at the California

JB: Astronomer Xinyu Dai at Ohio State University and his colleagues have
managed a first glimpse inside a quasar.
Xinyu Dai: Quasars are objects that are very far away. Because they are so
far away, when we look at them far away, directly, by imaging, they all look
like little dots.

发帖数: 103 | 19 相机那个是衍射，因为光圈是个小孔
quasar 不是喷出光，而是喷出物质。黑洞附近形成吸积盘，但是黑洞不能消耗掉吸积
盘上所有的角动量，于是就以喷流的形式喷出，形成jet。jet是垂直于吸积盘的。
天体里面有吸积盘的大多都有jet。quasar是星系尺度的黑洞，恒星级尺度的黑洞也有
，早期恒星也有，甚至中子星也有
jet是广泛存在的，具体形成机制还有一定争议，但是确实有这么回事 |

我用AcneFree, 雙管齊下效果不錯
