1、原文标题：NASA Launches Black Hole Hunter内容简介：概述：为了研究黑洞辐射的X射线，NASA发射了NuSTAR望远镜，此举将开启一扇感知宇宙的全新窗口。Hints:X-rayPaul HertzNASANuSTAREarthFiona HarrisonBlack Holes. Their gravitational pull is so intense that not even light can escape from them. As gas, dust and stars are sucked in, the material accelerates an
2、d heats up, generating powerful X-ray light emissions.And now NASA has launched a black hole hunter, a new telescope called NuSTAR.Paul Hertz is the director of NASAs astrophysics division.Stars, nebulae and black holes emit X-rays of the type that we use in medical X-rays, and these cannot be detec
3、ted from the surface of the Earth. But the NuSTAR telescope will focus these X-rays onto its digital camera and send the pictures back to Earth for scientific analysis.Scientists expect to start getting science data about a month after NuSTARs launch.It will be studied by people around the world, in
4、cluding NuSTARs principal investigator, Fiona Harrison.NuSTAR will open a whole new window on the universe, by being the very first telescope to focus high-energy X-rays. As such, itll make images that are ten times crisper and 100 times more sensitive than any telescope that is operated in this reg
5、ion of the spectrum.黑洞，其引力如此之强，以至于光都无法逃逸。当气体、尘埃和恒星被黑洞吸入时，这些物质运动加速并快速升温，散发出强大的X射线。日前，美国国家航空和宇宙航行局发射了一枚黑洞猎人被称为“核星”的新型望远镜。保罗?赫兹是NASA天体物理学部的主任。“恒星、星云和黑洞发出的X射线就是那种医用X射线，我们无法在地球表面探测到这些射线。但是核星望远镜会将这些X射线聚焦到其数码相机，然后将图片传回地球以便我们进行科学分析。”科学家们预期能在核星发射约一个月后开始取得科学数据。这些数据将被世界各地的人们研究，包括核星的首席科学家菲奥纳?哈里森。“作为首架聚焦高能X射线的望远镜，核星将为研究宇宙打开全新的窗口。相比于其他任何在这一光谱范围内作业的望远镜，核星能拍出清晰10倍，感光度高100倍的图像。”
