Stellar motions in the core of the giant galaxy do indeed suggest that it may have experienced a black hole merger in the not-too-distant past, says Gebhardt.
格布哈特说，在这个巨大星系的中心，恒星的运动的确说明，在不太遥远的过去该星系有可能经历过一次吞并黑洞的事件。
Our galaxy is so huge that dozens of lesser galaxies scamper about it, like moons orbiting a giant planet.
我们的银河系实在庞大，吸引着数十个较小的星系环绕着它奔跑，恰似环绕巨大行星旋转的卫星。
Its broad arms are distorted by gravitational interaction with a fellow Virgo cluster member, giant elliptical galaxy NGC 4697.
其宽广的旋臂被该星系团另一成员，巨型椭圆星系ngc 4697的引力作用所扭曲。
Thanks to German astronomers, we now have the most accurate measurements yet of the giant black hole that sits at the centre of our galaxy.
感谢德国天文学家，我们现在知道了躺在我们银河系中心的那个黑洞的精确尺寸。
Just below and to its right is fuzzy-looking Maffei 1, the closest giant elliptical galaxy to Earth.
它的下面偏右（在画面的左边中间）看起来毛绒绒一团的是马费伊1，离地球最近的巨型椭圆星系。
This is the first time a stellar black hole (as opposed those giant, galaxy-centered black holes) has been seen being born.
这是第一次发现正在出生的恒星黑洞(相对那些巨大的，位于星系中心的黑洞)。
One might say that the cluster has acted like a giant magnifying glass, or gravitational lens, in space - focusing, magnifying and distorting the images of the galaxy.
可以说，集群已采取行动，像一个巨大的放大镜，或重力透镜，在太空-聚焦，放大和歪曲的形象银河。
Thousands of sparkling young stars are nestled within the giant nebula NGC 3603, one of the most massive young star clusters in the Milky Way Galaxy.
