当局今年4月公布了人类有史以来拍到的第一张“黑洞照片”,立下天文学界的里程碑,惟该黑洞照却显得模糊,有鉴于此,美国太空总署(NASA)26日就释出一支模拟影片,让民众能以高解析度欣赏这个天文奇观。

影片中,环绕在黑洞外侧的橘红色碟状物称为“吸积盘”(Accretion Disk),由气体、星尘等物质组成,越靠近被吸入黑洞时,这些物质越以逼近光速的高速绕圈,粒子激烈撞击下,将X光及伽马射线以可见光的形态释放出来,让科学家得以接收、间接观测黑洞。

黑洞模拟高清照。

另外也可发现,吸积盘上下方皆隆起的部分,其实位置是在黑洞的“背后”。这是因为黑洞以强大重力扭曲光线,形成的重力透镜效应(Gravitational Lensing)。
