科学家用新的探测方法发现了一个隐藏的黑洞

Scientists find a hidden black hole using new detection method

Researchers have discovered a strange black hole-star pair, a finding that could open our eyes to millions of new black holes that, until now, have been hidden in the cosmos.

研究人员发现了一对奇怪的黑洞-恒星对,这一发现可以让我们看到迄今为止隐藏在宇宙中的数百万个新黑洞。

For years, scientists have assumed that there are millions of black holes in our galaxy. However, researchers can often only spot black holes that are in binary pairs with stars in which the black hole orbits and siphons matter from the star. This is because, when black holes accrete matter from their partner star, they emit bright, easy-to-spot X-rays.

多年来,科学家们一直认为我们银河系中有数百万个黑洞。然而,研究人员通常只能发现与恒星形成双星对的黑洞,黑洞围绕恒星运行并从恒星中吸出物质。这是因为,当黑洞从其伙伴恒星吸积物质时,它们会发出明亮的、容易被发现的X射线。

But many black holes in these pairings don’t orbit their star close enough to accrete mass and emit this bright signal, so they go undetected.

但是这些对中的许多黑洞并没有足够靠近恒星的轨道来吸积质量并发出这种明亮的信号,所以它们没有被发现。

However, in a new study, scientists demonstrated how dimmer black holes can be spotted in the night sky.

然而,在一项新的研究中,科学家们展示了如何在夜空中发现较暗的黑洞。
