No one really knows -- and no one really has a theory yet, as it was all just recently discovered. But it is an excellent excuse for some of my favorite graphics. See at right -- it will take a bit to load (at ~3 MB), so be patient.
Why isn't this small cluster of star masses completely. . . shredded, by the maw of this gargantuan black hole? Who knows? The only thing that seems certain here, is this confirms we still have a lot to learn about "the why's" of physics, on that scale. Here is the solid, but easily understandible Space.com, on it all:
. . .The Leo I dwarf galaxy, some 820,000 light-years from Earth, is only about 2,000 light-years across. Until now, astronomers thought the galaxy's mass was about 15 to 30 million times the mass of our sun. That's tiny compared to the Milky Way, which is estimated to weigh as much as 1.5 trillion suns and whose disk is over 100,000 light-years wide.
Unexpectedly, at the heart of the little Leo I sits a black hole that is nearly as large as the one at the heart of the entire Milky Way, a new study found. The discovery defies expectations as astronomers believed giant black holes grow from collisions between galaxies and should correspond with the galaxy's size. . . .
Onward. [I suppose there is the occasional shepherded moon, that isn't ultimately shredded, by his planetary neighbors -- by keeping the proper. . . distance. So too, with some entwined hearts -- and (now less-entwined) lives. . . . With a Zoom extended-family game night, via Jackbox up next, in about three hours.] Smiling. . . but faintly, so.
