答疑：xyfxyfxyf123This image shows the glow of hundreds of massive black holes in the universe. NASA says it's the best that current telescopes can provide. But this simulation shows what NASA expects NuSTAR will see when it surveys the extragalactic sky.
About a week after NuSTAR launches, its ten-meter mast will deploy, separating the mirrors from the detectors. That provides the distance required to focus the X-ray light into sharp images.
The telescope will be able to find black holes hidden behind screens of dust and gas. It will also be able to tell how quickly a black hole is spinning, which will help scientists learn how black holes form.
Again, NASA's Paul Hertz.
"Like all of our NASA missions, we're going to find unexpected things out there that will lead us to questions and answers that we aren't even anticipating at this time."
NASA scientists say one of NuSTAR's goals is to take a census of collapsed stars and black holes in the universe.图像表明宇宙中有上百个大质量黑洞的光芒，美国航空航天局称这是现今望远镜能够呈现的最佳图像。但是这种模拟图像也表明了，美国航空航天局期望“核星”在探索外太空时能够发现的东西。
“核星”发射大约一周后，它的10米桅杆将展开，使得镜片和探测器分离，这就给两者间提供了足够距离，使得X光能够聚焦到清晰图像上。
望远镜将能发现隐藏在灰尘和气体后面的黑洞，并能得知黑洞旋转的速度，这将有助于科学家研究黑洞是如何形成的。
美国航空航天局的保罗·赫兹接着说道：
“就和我们局里其他的任务一样，我们将去发现地球之外的事物，这些发现会带给我们新的问题和答案，而那些甚至是我们现在根本没能想到的。”
美国航空航天局的科学家们称，“核星”的任务之一是对宇宙中的坍塌星球和黑洞做一个普查。
