一 | 北京时间1月16日消息，我们的太阳系有一颗恒星和八颗行星。但其他星系可能远不止这些，而且会有两三颗恒星围绕彼此运行。
二 | As the US government ponders on what to do exactly about so-called unidentified aerial phenomena (UAP), which is how UFOs are often referred to nowadays, yet another strange sight that may or may not be one such phenomenon got spotted in the sky above the United States.,A video of the sighting, which apparently occurred on 22 May in the vicinity of Waterloo, Iowa, has recently been uploaded by the Hidden Underbelly 2.0 YouTube channel and depicts a somewhat indistinct glowing shape in the sky.,“It could be behind the clouds and this obscuring the UFO or the (sic!) could be something that is plasma based or even biological. Two things are for sure with this footage, I'm at a loss for what this could be and my mind is blown by this sighting,” the uploader wrote in the video’s description.,Prolific blogger and UFO hunter Scott C. Waring also suggested that the shape seen in the video was a UFO, arguing that “the object is partly cloaked so only a few sections” of it are visible.,However, one social media user who commented on the video on YouTube offered a more mundane explanation, suggesting that it was merely “the sun behind the clouds."。一组天文学家发现了一个由四颗恒星组成的星系，它隐藏在146光年之外。这个星系被命名为HD98800。天文学家利用智利的阿塔卡马大毫米阵列射电望远镜发现了它。射电望远镜是发现这个星系的关键，因为这些恒星被原行星盘所包围。据报道，最初的行星盘是指在行星形成之前出现在早期星系中的尘埃和气体环。最终，尘埃和气体会坍缩成行星，但在此之前，圆盘将阻止大部分光从星系中逃逸。然而，无线电波可以穿透灰尘。基于这一原理，科学家们利用射电望远镜在尘埃中发现了四颗独立的恒星。这四颗恒星形成了两对双星，一对在银河系的中心，另一对在数十亿英里外的轨道上。根据天文学家的说法，外对命名为aa和ab，而中心对命名为ba和bb。由四颗恒星组成的星系本身很奇怪，但真正让这个星系奇怪的是原行星盘。在大多数系统中，原始的行星盘与主星对齐。例如，在我们自己的太阳系中，所有的行星和小行星都在与太阳大致相同的平面上运动。HD98800的情况并非如此，它是一个由尘埃和气体组成的原行星盘，与中央恒星平面成直角。恒星系是人类发现的第一个具有这种垂直圆盘的双星系统，这表明宇宙中有许多未知现象等待发现。此外，最初的行星盘通常最终形成行星，这意味着以各种奇怪的角度围绕二元系运行的行星可能会出现。我们通常不从这些奇怪的角度寻找行星，因此这表明人类可以在未来探索这些行星。
