天文学家观测到一次罕见的宇宙灾难事件，一个黑洞撕裂并吞噬了一颗超大质量恒星。这次事件被昵称为"Whippet"（正式编号AT2024wpp），于2024年被发现1。这场灾难释放的能量约为太阳输出的400亿倍，产生了已知最强大的宇宙爆炸之一1。
黑洞撕裂恒星产生的震波以五分之一光速向外传播1。更引人注目的是，数月后科学家发现了意外快速移动的氦气信号，移动速度超过每秒6000公里1，表明某些结构可能在这场毁灭中幸存了下来1。这一发现由英国利物浦约翰摩尔斯大学的丹尼尔·珀利及其团队记录，相关论文已发表于《皇家天文学会月刊》2026年第549卷第1期1。研究人员利用帕洛玛天文台的茨威基瞬变设施、利物浦望远镜和美国宇航局的斯威夫特卫星进行了观测1。
Astronomers have observed a black hole shredding and consuming a supermassive star in an event nicknamed "the Whippet," officially designated AT2024wpp and discovered in 2024 1. The catastrophic encounter released energy equivalent to approximately 400 billion times the Sun's output, producing one of the most powerful cosmic explosions ever recorded 1. The resulting shockwave propagated outward at one-fifth the speed of light, detected through observations conducted with the Zwicky Transient Facility at Palomar Observatory, the Liverpool Telescope, and NASA's Swift satellite 1.
In a striking discovery, researchers led by Daniel Perley of Liverpool John Moores University found unexpectedly rapid-moving helium gas months after the initial disruption, traveling at speeds exceeding 6,000 kilometers per second 1. This anomalous signal suggests that some structural component of the star may have survived the violent destruction within the black hole's tidal forces 1. The findings, published in Monthly Notices of the Royal Astronomical Society in 2026, volume 549, issue 1, offer new perspectives on tidal disruption events and raise questions about what material can endure when caught between a black hole's immense gravitational forces 1.
