发现"大轮"银河系 挑战早期宇宙中银河形成理论 Discovery of "Big Wheel" galaxy challenges theories on galaxy formation in early universe.

“大轮”的发现 利用詹姆斯·韦伯太空望远镜 在早期宇宙发现的庞大星系 挑战了银河系形成方面的现有理论 The discovery of the "Big Wheel," a massive galaxy found in the early universe using the James Webb Space Telescope, challenges existing theories on galaxy formation. 大爆炸刚刚过去20亿年, 这个星系异常大, 类似于现代螺旋星系。 Existing just 2 billion years after the Big Bang, this galaxy is unusually large and similar to modern spiral galaxies. " 大轮 " 位于密密密的空间区域,发展迅速,表明目前的银河系演变模式需要加以完善。 Located in a densely packed region of space, the Big Wheel grew rapidly, suggesting that current models of galaxy evolution need refinement.
