   1 day ago · To make a black hole you need to start with a massive star. But at the ends of their lives, massive stars are incredibly unstable, ejecting fierce winds and expanding into red giants.

   And the most massive stars, over 30 solar masses, become stellar-mass black holes. Our understanding of this process, however, is largely based on observing the aftermath. For example, neutron stars in the Milky Way shining from within the remnants of the supernova explosion in which they were born, such as the famous Crab Pulsar (below), or Vela Pulsar (a pulsar is a type of neutron star).

   Nov 19, 2002 · The star's core collapses, igniting a shock wave that blasts the rest of the star into space. If the collapsing core is a few times the mass of our sun, gravity will crush it into an infinitely dense speck. However, models predict that rare stars at least 40 times heftier than our sun should plummet directly into black holes without exploding ...

   4 days ago · About 98% of the star's mass collapsed and created a black hole with about 6.5 solar masses. M31-2014-DS1 isn't the only failed supernova, or candidate failed supernova, that astronomers have found.

   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.

   Are Stars collapsing directly into black holes?

   Can stars produce black holes without a supernova explosion?

   • However, astronomers are now beginning to come around to the idea that some stars that produce black holes may do so without a supernova explosion. Researchers have occasionally noticed occurrences of failed supernovas — stars that begin to brighten as though they are about to explode, but which then falter and die away.

   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.

   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.

   When are black holes born?

   • Typically, black holes are born when stars die. When the most massive stars undergo gravitational collapse, the little nugget they leave behind is a black hole. That’s the pretty clearly established origin story.
