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。 The Justice Department has announced the arrest of a North Carolina man charged with leveling threats against a Jewish house of worship last week in the wake of the Hamas attack on Israel."I am going to take every one of you out in a way," Jeffrey Scott Hobgood allegedly said in an email to the Jewish organization on Oct. 11, according to court documents. "You will beg for your life ... you semite pieces of **** - will be annihilated."Even after law enforcement contacted him following the first email, Hobgood proceeded to send a second threatening message to the same organization two days later, prosecutors say."Guess what happens to traitors? ... Public execution. ... We are at war. ... If you think you semite pieces of **** are going to win, then you are delusional," he allegedly wrote, court documents show.Hobgood has not entered a plea, and he has no attorney listed in court documents.Hobgood's family members had previously reported to law enforcements threats that they say he allegedly made against them in the past year as well, according to his arrest affidavit.The FBI released data on Monday showing that anti-Jewish hate crimes increased by more than 37% in 2022 -- the second-highest number on record and the highest number in almost three decades. There were a total of 11,634 criminal hate crime incidents motivated by bias toward race, ethnicity, ancestry, religion, sexual orientation, disability, gender, and gender identity in 2022, according to the data.At least 1,400 people have died and 3,400 others have been injured in Israel since Hamas launched an unprecedented incursion from air, land and sea on Oct. 7, Israeli authorities said.。
二 | 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。
三 | 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。
四 | 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。
五 | 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。
六 | 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。
七 | 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。
