Astronomers have found a seemingly “impossible” black hole about 14,000 light-years away. Their observations, published in the November 28th Nature, suggest that the weird object weighs in at a staggering 68 times the mass of the Sun.
While much heftier black holes, dubbed supermassive, reside in the cores of most large galaxies, theories predict an upper limit of some 45 to 55 solar masses for a “stellar-mass” black hole that forms in the aftermath of a supernova explosion. According to Craig Wheeler (University of Texas, Austin), “This is clearly an interesting story, if verified.
