黑洞长啥样?美国宇航局公布最新黑洞模拟图(图)

科技世界 蓝色圈是小麦哲伦星云(SMC)的镜像,红色圈是阿法跟贝塔人马星座(Alpha and Beta Centauri)的镜像。 中新网12月11日电 据台湾“今日新闻网”11日报道,美国宇航局(NASA)近日利用计算机仿真绘图,画出一幅黑洞的正面观测图。结果发现,黑洞的引力不但会让周遭光线异常弯曲,且附近恒星就像“照镜子”一样,形成两两对称的镜像模式。 由于黑洞具有极强大的引力,会造成附近光线明显地朝着它弯曲,并在模拟画面上展现出独特的视觉扭曲。而这张由2MASS红外天空勘测所拍摄而成模拟图,就可看出每颗正常型态的恒星都会有两个明亮的图像,并平均对称于黑洞的两侧。 法国天体物理学家里亚佐罗(Alain Riazuelo)表示,在原始图像中,黑洞在大麦哲伦星云中心呈现阶层状的结构,但在这些仿真图像中,“我们将黑洞设定为图像中心,在光线被引力所吸引之下,黑洞附近能看见的恒星会比在宇宙其它地方多”。
