研究人员分析了NASA詹姆斯·韦伯太空望远镜的图像，发现早期宇宙中的星系通常是扁平细长的，就像冲浪板和泳池浮条一样，很少是圆形的，比如排球或飞盘。“我们研究的星系中，大约有50%到80%在二维空间中看起来是扁平的。”该研究的第一作者维拉杰·潘迪亚解释说，他是纽约哥伦比亚大学的NASA哈勃研究员。“看起来像泳池浮条或冲浪板的星系在早期宇宙中似乎很常见，这令人惊讶，因为它们在我们附近并不常见。” 该团队专注于韦伯提供的大量近红外图像，即宇宙演化早期发布科学（CEERS）调查，从中挑选出估计在宇宙6亿至60亿岁时存在的星系。 图片: 遥远星系的形状样本 研究人员分析了来自NASA詹姆斯·韦伯太空望远镜的宇宙演化早期发布科学（CEERS）调查中出现的遥远星系，发现当宇宙只有6亿到60亿年的时候，出现了一系列奇怪的形状。...
