Webb 望远镜在早期宇宙中发现神秘的"小红点" 可能是新的黑洞恒星 Webb Telescope finds mysterious "Little Red Dots" in early universe, possibly new black hole stars.

使用James Webb空间望远镜的天文学家 已经发现了几百个神秘的紧凑物体 叫做小红点 Astronomers using the James Webb Space Telescope have discovered hundreds of mysterious, compact objects called "Little Red Dots" from just a few hundred million years after the Big Bang. 这些极其明亮的红源释放出强烈的红外线和紫外线光,但缺乏典型的黑洞X射线暴,有快速移动的气体和不寻常的能量特征。 These extremely bright, red sources emit intense infrared and ultraviolet light but lack X-ray bursts typical of black holes, with fast-moving gases and an unusual energy signature. 与已知的星系或黑洞活动不同,它们的特性表明一种新的现象:可能是“黑洞恒星”——中央黑洞环绕着一个稳定而发光的气体云环绕的假设物体,与恒星表面相类似。 Unlike known galaxies or black hole activity, their properties suggest a new phenomenon: possibly "black hole stars"—hypothetical objects with a central black hole surrounded by a stable, glowing gas cloud resembling a star’s surface. 这种模型是对长期理论化的"准恒星"的现代化版本,可以解释X射线的缺乏和极端亮度,尽管形成和稳定性仍然未知. This model, a modern take on the long-theorized "quasi-star," could explain the lack of X-rays and extreme brightness, though formation and stability remain unknown. 研究结果表明,在早期宇宙中,黑洞日益扩大比想象的更为普遍,这凸显了在理解宇宙起源方面存在的重大差距。 The findings imply growing black holes were more common in the early universe than thought, highlighting major gaps in understanding cosmic origins.
