在浩渺的宇宙深处，一场跨越时空的侦探剧正在上演，主角便是我们所在的银河系中心那个神秘莫测的超大质量黑洞——人马座A*（Sgr A*）。近日，天文学家利用尖端射电望远镜揭示了一幅前所未见的壮丽景象：数百条奇特的弦状结构犹如横亘在银河心脏区域的宇宙音符，它们或是古代黑洞爆发留下的震撼痕迹，诉说着那段遥远而又狂暴的历史。
Deep in the vastness of the universe, a time-transcending whodunit is unfolding, featuring Sagittarius A* (Sgr A*), the mysterious and unpredictable supermassive black hole at the center of our Milky Way galaxy. Recently, astronomers using cutting-edge radio telescopes have revealed a magnificent sight never seen before: hundreds of strange string-like structures like cosmic notes across the heart of the Milky Way, which are either shocking traces of an ancient black hole eruption, telling a distant and violent history.
