NASA Finds Rare Black Hole Eating a Star Far From Galaxy Center
NASA's Swift Observatory saw a rare event where a black hole far outside a galaxy's core tore apart a star, helping scientists find more wandering black holes.
NASA has found a rare black hole. It is eating a star far from a galaxy center. Scientists used the Swift Observatory to see this event. The event is called a tidal disruption event. It happens when a black hole pulls a star apart. This black hole is very big. It has the mass of one million suns. The galaxy is about 750 million light-years away. The black hole is more than 30,000 light-years from the center. This is a very unusual place for such a black hole. Before 2024, scientists only saw these events in galaxy cores. The star became very bright and hot during the event. It shone with the light of ten billion suns. The temperature reached about 54,000 degrees Fahrenheit. The Zwicky Transient Facility first found this event in November 2025. It used an AI tool to spot the flare. The flare was very bright in ultraviolet light. Swift measured the heat and light of the event. This discovery is important for astronomy. It proves a new way to find wandering black holes. Scientists think this black hole came from another galaxy. That galaxy merged with the current host galaxy. Future telescopes will use this method to find more events. The Vera C. Rubin Observatory will help with this work. NASA's Nancy Grace Roman Space Telescope will also help. This helps us understand how common wandering black holes are. The Swift mission has worked for more than 20 years. It is now waiting for an orbit boost this summer. This news helps us learn more about the universe.

美国宇航局发现了一个罕见的黑洞。它正在吞噬一颗远离星系中心的恒星。科学家们使用斯威夫特天文台观察到了这一事件。这一事件被称为潮汐瓦解事件。当黑洞将一颗恒星撕碎时，就会发生这种情况。这个黑洞非常大。它的质量相当于100万个太阳。这个星系距离我们约7.5亿光年。黑洞距离星系中心超过3万光年。对于这样一个黑洞来说，这是一个非常不寻常的地方。在2024年之前，科学家们只在星系核心观察到过这类事件。恒星在事件过程中变得非常明亮和炽热。它发出了相当于100亿个太阳的光芒。温度达到了约54,000华氏度。兹威基瞬变设施在2025年11月首次发现了这一事件。它使用人工智能工具来发现耀斑。该耀斑在紫外光下非常明亮。斯威夫特测量了该事件的热量和光线。这一发现对天文学很重要。它证明了寻找流浪黑洞的新方法。科学家们认为这个黑洞来自另一个星系。那个星系与当前的宿主星系合并了。未来的望远镜将使用这种方法来发现更多事件。薇拉·鲁宾天文台将协助这项工作。美国宇航局的南希·格雷斯·罗曼太空望远镜也将提供帮助。这有助于我们了解流浪黑洞有多普遍。斯威夫特任务已经运行了20多年。它现在正在等待今年夏天的轨道提升。这条新闻有助于我们更多地了解宇宙。
