西内SINE

你知道吗，在我离开中国之前，我就听说过亚利桑那大学，它位于我和奥拉去过的奥拉克还要靠南很多的地方。就在最近，比如2019年，他们通过让世界各地的射电望远镜都聚焦它，拍摄到了遥远星系中的黑洞。那张照片在网上有，但我把它分享在这里，方便您查看。
You know, even before I leave China I hear of University of Arizona farther south than Oracle where I went to with Aura. Very recently, like 2019, they got picture black hole in distant galaxy by getting radio telescopes all over world focus on it together. That picture on internet, and I put it in this note in case you not see it.

但在那之前，大约30年前左右，我们只能看到银河系中心的红外线，一个黑洞。1993年1月美国天文学会凤凰会议上的照片支持了他们在1990年6月新墨西哥州阿尔伯克基会议上从射电望远镜图像得到的结论。我很高兴能去这些地方，那里有好多人在研究这些东西。
But even before that, thirty years or so, could see at center of Milky Way is infrared light, a black hole. Pictures at January 1993 Phoenix meeting of American Astronomical Society support conclusions from radio telescope images at earlier American Astronomical Society meeting June 1990 Albuquerque, New Mexico. I so glad be where other people work on these things.

西北大学法尔哈德·优素福-扎德出席了这次会议，他和同事们用新墨西哥州索科鲁的巨型射电望远镜拍摄的图像表明，银河系中心的有某种东西每5到1万年就会消耗掉一颗恒星。使用超大阵列射电望远镜，优素福-扎德和同事发现这种东西吹走了银河系中心附近一颗恒星的大气层。它的大气层像彗星的尾巴一样拖着，指向他们认为是黑洞的地方，在其它星系中也可以看到类似的情况。
Images Northwestern University Farhad Yusef-Zadeh present at that meeting, images he and colleagues made with giant radio telescope by Socorro, N.M. indicate something at center of Milky Way consume a star each 5 to 10 thousand years. Using Very Large Array radio telescope, YusefZadeh and colleagues found something blowing away the atmosphere of a star near Milky Way center. Its atmosphere trailed out like the tail of a comet that pointed at what they think is black hole, because similar seen in other galaxies.

来自银河系中心的能量表明它在过去的50到100亿年间消耗了100万颗恒星。这个恒星漩涡中心的引力如此强烈，甚至连光都会偏离。因此，第一颗恒星分解了，然后开始吸引别的恒星，他们把它称之为“黑洞”。
Energy from center of Milky Way, suggest it has consumed a million stars over past 5 to 10 billion years. Gravity at center of this whirlpool of stars is so intense not even light leaves. Is why they say “black hole” for the first star that collapse and began pulling in other stars.
