Last month, NASA released two arresting images of black holes. The first: a simulation of how light bends around a black hole surrounded by a glowing disk of infalling matter. The second: an image, gathered by optical, infrared, and X-ray telescopes on Earth and in space, of three supermassive black holes on a collision course.

These images follow a slew of findings that confirm Albert Einstein's model of gravity, from the celebrated Laser Interferometer Gravitational-Wave Observatory (LIGO) detection of gravitational waves to the image, published earlier this year, of a black hole's "shadow." Because they exert so much gravitational force that even nearby light falls into them, black holes are very black. Compared with a black hole, any black clothing you have is actually navy blue.

Yet black holes are also thought to produce some of the universe's brightest known lights. These include blazars, the extremely hot jets of matter produced by the gases orbiting supermassive black holes, and gamma-ray bursts, the explosions of high-frequency radiation thought to occur when a black hole swallows a binary neutron star.

上个月，美国国家航空航天局捕捉到了两张黑洞的图像。第一张图像：模拟光如何在黑洞周围弯曲，黑洞周围环绕着一个发光的碟状的不断下落的物质。第二张图像：通过在地球上和太空中的光学、红外和x射线望远镜收集到的三个超大质量黑洞碰撞轨迹的图像。

数学焦虑症是对数学的一种挥之不去的恐惧，它影响着大学生的选课和择业。它会阻止本有能力在科学、技术、工程和数学领域取得成功的学生的选课与择业。与男性相比，女性往往更容易对数学感到焦虑，对自己的数学能力缺乏信心，这可能有助于解释为什么她们在许多科学、技术、工程和数学领域的代表性仍然不足。

然而，黑洞也被认为产生了一些宇宙中已知的最亮的光。其中包括环绕超大质量黑洞的气体所产生的极热物质喷流，以及伽马射线暴，即黑洞吞噬双星时所发生的高频辐射爆炸。
