Stellar mass black holes form when massive stars die. If you have read How Stars Work, then you know that a star is a huge, amazing fusion reactor. Because stars are so massive and made out of gas clouds, their own intense gravity is always trying to collapse them. The fusion reac...
1. How do scientists know where black holes are located? By sending research equipment into them to get data They can see them through telescopes. By the way gases and stars move and act near black holes By the way that light reflects out of them 2. What is one way a stellar bla...
Stars are held in perfect balance by two opposing forces. There’s the inward pressure of gravity, attempting to collapse the star, counteracted by the outward pressure of the emitted radiation. This artist’s concept illustrates a supermassive black hole with millions to billions times the mass ...
Two massive black holes smashed together and completely changed what we know about the universe. This physics-altering collision simply doesn't make sense.
Even light waves are sucked in, which is why black holes are black. These bizarre objects arise like phoenixes springing from the ashes of dead stars. When massive stars reach the ends of their lives, the hydrogen that they've been fusing into helium is nearly depleted. So, these monster ...
“Intermediate-Mass Black Holes are difficult to observe,” explains the GSSI researcher, “the current observational limits do not allow us to say anything about the population of IMBHs with masses between 1,000 and 10,000 solar masses, and they also represent a headache for scientists in ter...
How does the number of these early-generation stellar-core black holes compare with the total number of currently luminious stars? Are there enough black holes to account for "dark matter"? I.e. what fraction of the matter that "condensed" from Big Bang energy is now in black holes?I ...
s still not clear whether they formed outside of the danger zone and then wandered in or whether they actually formed in the danger zone,” says Figer. While the colossal gravitational pull of the supermassive black hole makes it unlikely that the stars could have formed where ...

“All of the galaxies and black holes in our sample are very well characterized at multiple wavelengths, with superb measurements in the infrared, optical, ultraviolet, and X-ray bands,” Zou said. “This allows for robust conclusions, and the data show that, at all cosmic epochs, more mas...
