詹姆斯-韦伯望远镜是历史上最强大的望远镜,于2021年12月25日发射,其任务是观察第一批星系和恒星的形成,研究星系的演变,并看到恒星、行星和宇宙本身的形成过程。 而就在刚才,美国宇航局披露了第一张詹姆斯-韦伯的图像,这是迄今最深、最清晰的早期宇宙的图像。

"美国宇航局的詹姆斯-韦伯太空望远镜产生了迄今为止最深、最清晰的遥远宇宙的红外图像。 被称为第一韦伯深场的这张图像显示了SMACS 0723星系团,并且充满了细节,"美国宇航局说。 这张令人难以置信和前所未有的图像,显示了130亿年前的宇宙,大爆炸后仅仅7亿年。请看下面这张由詹姆斯-韦伯拍摄的历史性的、前所未有的宇宙照片(如果你想看高分辨率和放大的照片,请点击这里):

这张史无前例的图片是由近红外相机(NIRCam)经过12.5小时的不间断曝光后拍摄的。"韦伯将这些遥远的星系带入了清晰的焦点--它们拥有以前从未见过的微弱的微小结构,包括星团和模糊的特征。 研究人员很快美国宇航局解释说:"随着韦伯搜索宇宙中的第一个星系,我们将开始更多地了解星系的质量、年龄、历史和组成。

如上图所示,数以千计的星系--包括有史以来在红外线中观察到的最微弱的天体--首次出现在韦伯的视野中。 这片浩瀚的宇宙覆盖了一片天空,对一个地面观察者来说,似乎与地球的大小差不多。一粒沙子在手臂长度上的距离。

这台耗资100亿美元的望远镜正在观测太空中最古老和最遥远的星系,并将带来对宇宙的新认识。 到目前为止,望远镜的距离记录由哈勃保持,它观测了距离地球约134亿光年的一个星系。

詹姆斯-韦伯被认为是历史上最大的空间科学望远镜。 仅仅是它的遮阳板,即保护它不受太阳光和热量影响的结构,就有一个网球场那么大,重量超过6吨。 我们可能很快就能通过它的图像发现宇宙的起源。

哈勃和詹姆斯-韦伯望远镜在清晰度上的巨大差异
