are moving at 99.99 percent of the speed of light. and are pointed directly at the Earth.
[AI] 它们以99.99%的光速运动。并直接指向地球。
These jetted. Earth-pointed. hyperactive and supermassive black holes
[AI] 这些是喷气式飞机。土尖的。超活跃和超大质量黑洞
are called blazars. or blazing quasars.
[AI] 它们被称为blazars。或者燃烧的类星体。
What makes blazars so special is that they're some of the universe's
[AI] blazars之所以如此特别，是因为它们是宇宙的一部分
most efficient particle accelerators.
[AI] 最有效的粒子加速器。
transporting incredible amounts of energy throughout a galaxy.
[AI] 在整个星系中输送难以置信的能量。
Here. I'm showing an artist's conception of a blazar.
[AI] 在这里我正在展示一位艺术家对布拉查的构思。
The dinner plate by which material falls onto the black hole
[AI] 物质落入黑洞的餐盘
is called the accretion disc.
[AI] 被称为吸积盘。
shown here in blue.
[AI] 这里以蓝色显示。
Some of that material is slingshotted around the black hole
[AI] 其中一些物质被弹射在黑洞周围
and accelerated to insanely high speeds
[AI] 加速到了疯狂的高速
in the jet. shown here in white.
[AI] 在飞机上。此处显示为白色。
Although the blazar system is rare.
[AI] 虽然blazar系统很少见。
the process by which nature pulls in material via a disk.
[AI] 自然界通过圆盘吸入物质的过程。
and then flings some of it out via a jet. is more common.

We'll eventually zoom out of the blazar system
[AI] 我们最终将缩小blazar系统
to show its approximate relationship to the larger galactic context.
[AI] 显示它与更大的银河系背景的近似关系。
Beyond the cosmic accounting of what goes in to what goes out.
[AI] 超越宇宙对什么进入什么输出的解释。
one of the hot topics in blazar astrophysics right now

is where the highest-energy jet emission comes from.
[AI] 是能量最高的喷射源。
In this image. I'm interested in where this white blob forms
[AI] 在这幅图中。我感兴趣的是这个白色斑点在哪里形成
and if. as a result. there's any relationship between the jet
[AI] 如果。因此这架喷气式飞机之间有什么关系吗
and the accretion disc material.
[AI] 吸积盘材料。
Clear answers to this question
[AI] 这个问题的明确答案
were almost completely inaccessible until 2008.
[AI] 在2008年之前几乎完全无法进入。
when NASA launched a new telescope that better detects gamma ray light --
