印度天文学家发现阿拉克南达星系 是大爆炸15亿年后的螺旋星系 挑战早期星系形成的理论 Indian astronomers found Alaknanda, a spiral galaxy from 1.5 billion years after the Big Bang, challenging theories on early galaxy formation.

使用美国航天局詹姆斯·韦伯空间望远镜的印度天文学家已经发现了阿拉克南达,在大爆炸挑战这种复杂的螺旋结构不可能在宇宙如此早期存在的长期信念之后仅仅15亿年后,就形成了一个庞大、结构完善的螺旋星系。 Indian astronomers using NASA’s James Webb Space Telescope have discovered Alaknanda, a massive, well-structured spiral galaxy formed just 1.5 billion years after the Big Bang—challenging the long-held belief that such complex spiral structures couldn’t exist so early in the universe. 银河系与银河系相似,显示两种对称螺旋臂和快速的恒星形成,与当前的星系进化理论背道而驰。 The galaxy, resembling the Milky Way, shows two symmetric spiral arms and rapid star formation, defying current theories of galaxy evolution. 它的发现在引力透镜的帮助下 表明早期宇宙 可能比以前想象的更有组织 Its discovery, aided by gravitational lensing, suggests the early universe may have been more organized than previously thought.
