“We are tremendously privileged to be able to study the center of the galaxy, and have this exquisite laboratory to play with, to get insight into the fundamental physics of black holes, and also their astrophysical role in the formation and evolution of galaxies. You can also ask what kind...

But mostly the middle of all those stars is the perfect place for black hole formation, with lots of dust and gas.阅读短文,回答问题。51. How many black holes may there be in the center of our galaxy?52. Have scientists already known about a supermassive black hole at the center of ...
A“regular” cluster is sphere-shaped, symmetrical, and most dense in the middle, uh,with the greatest number of galaxies concentrated in the middle of the cluster. An “irregular” cluster might appear to be lopsided, asymmetrical, with a low concentration of galaxies in the center. ...

NASA’s James Webb Space Telescope has captured a tightly bound pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. Look for them at the center of the red diffraction spikes, appearing as an orange-white splotch. (Image credit: NASA, ESA, ...
Is it Really Empty? In general, voids are not completely empty. Astronomers have discovered about 60 galaxies inside the Boötes Void, which, for a region of that size, are not many. As it turns out, space is not very neat and tidy, and there are clusters of universes like there are...
normal matter we could see. Decades later, Vera Rubin famously noted that stars in spiral galaxies rotate around the galactic center far faster than they ought to, leading to later studies showing that spiral galaxies must be made up of about six times as much dark mass as the regular kind...
That does not mean it is the most distant thing we can feel, however. According to astrophysicist Alexander Kashlinsky of NASA's Goddard Space Flight Center, something from way beyond the edge seems to be pul...
