SINE

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.

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.

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.

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.
