   Apr 6, 2023 · This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long "contrail" of newborn stars, twice the diameter of our Milky Way galaxy. It's likely the result of a rare, bizarre game of galactic billiards among three massive black holes.

   Could supermassive black holes ever form a star?

   • But a handful of observations of supermassive black holes in the very early universe have suggested that there’s more to the picture. In 2006 Natarajan and her colleagues proposed a radical new explanation for how disks of gas could collapse directly into abnormally massive baby black holes without ever forming a star.

   Can black holes form without stars?

   • Astrophysicist Priyamvada Natarajan predicted that black holes can form without the help of stars. New observations support her theory By Zack Savitsky This image contains the most distant black hole ever detected in x-rays, a result that may explain how some of the first supermassive black holes in the universe formed.

   How did black holes become supermassive after the Big Bang?

   • Primordial black holes (PBHs) could have been produced directly from external pressure in the first moments after the Big Bang. These black holes would then have more time than any of the above models to accrete, allowing them sufficient time to reach supermassive sizes.

   How big is a black hole compared to a star?

   • In nearby galaxies, the mass of all the stars is often 1,000 to 10,000 times the mass of the central black hole. But in these direct-collapse scenarios, for a brief period of time, the mass of the black hole could actually be comparable to the mass of the stars.
