韦布空间望远镜（JWST）发现的“小红点”可能是“黑洞恒星”

天文学家在韦布空间望远镜观测到的早期宇宙数据中发现了神秘的“小红点”。最新研究提出，这些天体可能是一种被称为“黑洞恒星”的特殊结构，有助于解释大爆炸后超大质量黑洞的快速形成机制。

Little red dots have puzzled astronomers since their discovery in JWST data from the Universe’s deep past. Their ‘powering engines’ might resemble a newly discovered phenomenon dubbed a “black hole star”—an early, rapidly growing black hole wrapped in dense gas. This object, described in a study published today in Nature by researchers at the Institute of Science and Technology Austria (ISTA) and international collaborators, may help explain how billion-solar-mass black holes formed so soon after the Big Bang.
